Breitling Colt Oceane Chronometer Ladies Wristwatch

WWI era John Bruce sterling silver chronometer deck watch, nr 39252. The silver case stamped with a London hallmark, dated 1915, mm William Thomas Bullock. The National Maritime Museum ledger records (pg 7376) show that the watch was acquired by the Admiralty in 1915 (WWI era) 'with SS Orcoma' [1]. The ship was requisitioned for conversion to an Armed Merchant Cruiser in March 1915 and commission for service in the April [2]. It is thought the watch was part of the ships existing equipment in 1915. John Bruce and Sons, Liverpool was founded in the 1860's, starting as an optician and chronometer maker of Wapping, Liverpool and later 60 South Castle Street. [3]. The company was recorded as makers of fine marine chronometers to the Queen of Spain and winners of the Liverpool Gold Medal in 1886 [4]. This watch carries a signature plate inside that corresponds with the typescript used by the company in the late 19th and early 20th century. SS Orcoma carried out operations as part of the Grand Fleet in the Scapa Flow and on escort duty around the African coast. In 1918 Orcoma's log details show voyages between Halifax, Nova Scotia, New York, Glasgow and Liverpool. The ship's captains were Charles W. Bruton (1915-1916) and Robert H. Coppinger (196-1919) [7]. The Orcoma was returned in October 1919 and broken up in June 1933 by Hughes Bolckow Co. Ltd.,Blyth. [1] https://www.rmg.co.uk//collections/archive/rmgc-object-274122 [2] Screw Steamer Orcoma built by Wm.

A fine and rare second quarter 20th Century Swiss centre-seconds two-day marine chronometer with detent escapement by Paul Ditisheim, la Chaux-de-Fonds, number 130, the three tier box with brass corners and recessed handles opening to reveal the 10cms silvered dial with up and down subsidiary wind marker over the bold signature 'PAUL DITISHEIM, LA CHAUX-DE-FONDS' and further marked 'Grand Prix Paris 1900; Grand Prix Berne 1914, 'Maker TO THE BRITISH GOVERNMENT, HOLDER OF THE KEW AND TEDDINGTON RECORDS' and 'Maker TO THE UNITED STATES NAVY RECORD HOLDER NEUCHATEL OBSERVATORY 305 STATE PRIZES', the centre seconds hand reading against an outer Arabic scale marked in half-second increments, and enclosing the Roman and Arabic subsidiary time dial marked for hours and minutes, all framed by an angled sight ring, in a chromed bowl with integral winding key set to the underside, in chrome gimbals, the latter with a large hand-setting knob below the VI position, the lacquered movement signed in a rectangular reserve above 'CENTRAL SECOND MARINE CHRONOMETER seven swiss patents', on a cross-hatched background, the movement with a pair of circular plates mounted on the dialplate, united by turned pillars and with high beating balance wheel and detent escapement with blued steel spring and gold 'scape wheel in jewelled settings mounted on the backplate within a protective glazed cap, the three-arm balance bridge futher signed 'Guillaume Compensating Balance' and numbered 130, the outer box case with ivory plaque inscribed with maker's name, town and timepiece number, 18.5 x 18.5 x 20cms.Comparable literature:von Osterhausen: Paul Ditisheim Chronometrier, Antoine Simonin, 2003.Tony Mercer, Chronometer Makers of the World, NAG Press 1991Whitney, The Ship's Chronometer, AWI Press, 1985,von Bertele, Marine and Pocket Chronometers, Schiffer, 1991Gould, The Marine Chronometer, Its History and Development, ACC 1989.Notes: Ditisheim was a great pioneer in precision timekeeping in the early part of the last century. Mercer gives an excellent overview of the numerous prizes that were awarded to him. As well as making the smallest watch in the world for the Sultan of Oman, Ditisheim made huge improvements in the analysis and production of watch oils, investigated barometric compensation and wrote widely on other horological subjects and past makers. He was held in high esteem by his peers. Indeed, when Gould first published the standard work on chronometers in 1922, he included a picture of a very similar centre seconds chronometer in plate XXXVII as an example of modern chronometry with the following comments:"In closing this chapter, it may be of interest to give a short description of the new type of chronometer recently introduced by the firm of Paul Ditisheim, which contains a number of the devices just described.The machine, which is shown in Plate XXXVII, has, as will be noticed, a centre-seconds hand, the hours and minutes being shown on a subsidiary dial. The winding is affected by a permanently attached button at the bottom of the case, and mechanism is provided for setting the hour and minute hands in the same manner as those of a keyless watch. In addition, the balance and escapement are mounted so as to form a complete unit, and can at any time be detached (and if necessary, replaced by duplicates) without disturbing the remainder of the mechanism. The balance is of the "integral" type, with which M.Ditisheim's name has long been associated, and the escapement of the spring detent pattern, beating half seconds (although a lever escapement, beating fifths of a second, can be substituted). The machine has a gong-barrel and runs for 54 hours. experiments are, I understand, being directed towards providing later models with a barometric compensation, consisting of a moveable cap fitting over the balance.While, of course, extremely up-to-date and a very fine example of modern horological development, this design is, in a way, a complete compendium of the chronometer's history. It brings together Harrison's centre seconds hand and his provision for setting the hands, Kendall's and Cole's dials, Le Roy's going barrel, Barraud's attached key, Breguet's method of using interchangeable parts, Ulrich's plan of detachable escapement and balance, the escapements of Earnshaw and Mudge and Hutton's auxiliary. It supplies a convincing proof, if any were needed, that the development of the chronometer is by no means finished, and that while utilising to the full the knowledge of the present-day, much may also be gained from a study of the past."It is not known how many examples of these detent escapement chronometers were made by Ditisheim, but it would appear to be very few indeed. Number 230 is illustrated in Osterhausen p51, number 101 in Gould and number 112 in von Bertele.Self-declaration ivory reference NDRKD2P9

Exhibit P59.Based on the number, it is thought that this chronometer was made around 1882.The micrometric balance, or as it was marketed, the 'Double Compound Micrometric Equation balance', uses cone shaped weights and three central strips of metal to account for temperature error, including middle temperature error. There is also a collar of brass that partially surrounds the balance, the idea being that, should the fusee chain break, the escapement would still be protected. The escapement was commended when it was introduced around 1862, as allowing the owner to adjust the chronometer's rate without needing to remove the balance.Blake, W.

Ticking and striking. 15.5cms (6ins) highFootnotes:Provenance: Purchased from Tony Woodburn. James Grohé was born in 1803 in Baden, Germany. It is unclear where he served his apprenticeship, but around 1829 he came to the UK and established himself as a watch and clock maker in London. Interestingly, an entry in the 1831 London Morning Post makes brief reference to a James Grohe, who is described as a French and Genevan watchmaker. Baden is an area of Germany, situated between the French and Swiss borders. It is not known exactly where in Baden Grohé originally lived and it is possible he was educated, horologically or otherwise, in France and/or Switzerland.He is recorded as having taken over a watch and clock shop on Wigmore Street in 1834. The shop was originally the premises of the celebrated Charles Haley, who patented a chronometer remontoire escapement in 1796. It appears that Grohé purchased the shop from Haley's son, the previous business being 'Haley & Son.'An 1838 insurance certificate shows him working at 7 Wigmore Street next to Cavendish Square, as a clockmaker. A few months later, he is also recorded as occupying 3 Wimpole St. Cavendish Square and practicing as a watchmaker, possibly indicating separate premises for each trade. By 1843, he is advertising as a clock and watchmaker from the Wigmore address. At some point he married Harriet, a native of Marylebone and a year his junior. By 1845, the couple had two children, Catherine Elizabeth, and Mary Theresa. That same year, Grohé applied for, and was granted, British naturalisation. In 1852, Grohé was still working out of the Wigmore Street premises and advertising as a watch and clock maker. Possibly around this time, Grohé began to be supplied with carriage clock movements by Holingue Frères, Raingo Frères, and later Drocourt, these last movements being supplied in the 1870's. Some carriage clocks are known with the dial signed 'Grohé a Paris', though whether he had an actual shop in Paris remains unknown, no reference having been found of one. One of the carriage clocks, a repeater, was purchased by Queen Victoria in 1855 and is inscribed 'To Princess Helen Victoria by Queen Victoria in 1855', indicating that Grohé's business must have been thriving. The 1861 census records his full name as John James Grohé and describes him as a watch and clock maker, with his residence listed as 7 Wigmore Street. Harriet is also mentioned living at this address, as are three servants; a cook, a porter and a housemaid. By 1864, the 7 Wigmore Street shop had become 'Grohe Pennington & Typke'. It appears that Grohé had sold his business to John Pennington and Herrmann Wilhelm Typke between 1862-1864, possibly moving to 47 Princes Square, Bayswater, immediately after the sale.John Pennington was part of a dynasty of celebrated chronometer makers; presumably he was apprenticed to his father Robert Pennington Jr. though no record of this is known. After his marriage, he self-described as a 'gentleman' rather than a 'chronometer maker' on official documents. In 1846, however, he entered into partnership with his father, exhibiting a novel chronometer balance designed to control middle temperature error, at the Great Exhibition of 1851. His father died in 1854, and John continued the shop for another two years, before moving to various central London locations, eventually settling at 7 Wigmore Street.Herrmann Wilhelm Typke was born around 1821 in Prussia, and moved to the UK around 1849, setting himself up as a watchmaker. It is unknown where he served his apprenticeship, though it seems likely, considering his age when he moved, that it was served in Prussia. By 1859, he had married and was working out of 26 Devonshire Street, Portland Place in Middlesex. This same year he met John Pennington and the two became friends. Two years later, Pennington supported Typke's successful petition for naturalisation, along with several of Typke's neighbours. His petition also reveals that in 1861, he had five children, though their identities remain unknown. Grohé died in 1872, at 47 Princes Square, Bayswater in Middlesex, leaving around £25,000. It might be that Harriet predeceased him, though this is not definite. His will was proved by his two children, Catherine Elizabeth who had married a German merchant, and Mary Theresa, who had also married a German merchant; whether the couples were living in the UK or Germany is not indicated. William Wier Marshall and Frederick Gould, both listed as Esquires, also served as executors, but their relation to Grohé is unclear. Despite his death, entries continued to appear in trade directories under his name. In 1882 he is listed as working out of 24 Wigmore Street. By 1895, his address is listed as 3A Wimpole Street, Cavendish Square, an address he apparently vacated before his death. Around 1910, his entry has changed in trade directories to 'James Grohé, watchmaker, late 3A Wimpole St. & 24 Wigmore St. removed to Smith (Bolton), 26 Duke St. Manchester Sq. TN755 Paddington.' This entry continues to be recorded through 1920. It is known that Pennington and Typke would advertise their business as 'Pennington and Typke, successors to Grohe' until at least 1870, sometimes even signing new pieces simple as Grohé, until the early 1880's. John Pennington died in 1882, and it appears that Typke changed the signature of the business to 'Herman William Typke, Watchmaker, and James Grohe, Watch and Clock Maker.' Oddly though, in the same trade directories that list Grohé, there is a separate entry for Typke which reads 'Typke, Herman William (successor to Grohé)', though both addresses match. A very enthusiastic article did appear in 1893, in which Typke's shop at 24 Wigmore Street is lavishly described, and it is noted that he is a maker to the Queen and Royal Family. This may have been from Queen Victoria's purchase, in 1855, of a carriage clock from Grohé. The article also states that Typke took over Grohé's shop in 1849 (the year Typke moved to the UK), with no mention of the partnership between himself and Pennington. Whether this was a mistake on the writer's part or intentional misdirection from Typke remains unknown. Typke died in 1909, so it is unclear who continued to list James Grohé's details in the trade directories for the next 11 years, or why.

A very rare and historically interesting late 19th century two-day marine chronometer movement that took part in Ernest Shackleton's Nimrod expedition from July 1907 to September 1909.

Now set into a 20th century mahogany mantel piece case. 16cms (6ins) highFootnotes:Robert Gardner was born 1851 in Glasgow, to Robert Gardner, a horological supplies wholesaler. He was apprenticed to a clockmaker in Glasgow, and later, in 1871, to a London watchmaker, Troy Thomas. In 1875, his father died, and the business passed to Robert and his brother John. Robert returned from London to run the family business with John. Their partnership was short lived, however, and by 1878 Robert had established his own watchmaker's shop in Glasgow. Apparently, he was travelling extensively at this time, to both the Continent and the United States, all in the pursuit of discovering improved horological techniques. In 1880, some ship owner friends in Glasgow commissioned him to go to London and buy them some chronometers for their ships. After his return, it seems he became fixated with chronometers and by 1885, he was again living in London; he was married that same year, to A--, who was 11 years his junior. In 1886 he had established his workshop in his home at 20 Lloyd Square, Clerkenwell Road; he gradually moved into marine chronometers, originally purchasing finished Kullberg chronometers, and then using the bought stock from James Nelson, who had since retired and moved to New Zealand. Eventually, Gardner began making his own chronometers, with one of his chronometers taking first place in the 1897/98 Greenwich Trials. His son, Malcolm, had been born the year before, in 1896. Once he began making his own chronometers, he became increasingly engrossed in making the best chronometer balance with the optimum spring combination to ensure isochronism. This included fitting two and three in one balance springs, and also mercury compensated balances to attempt to overcome middle-temperature error. These balances built on the work of Le Roy and E. T. Loseby; in essence, a custom-made mercury filled bulb and stem were formed into a hook shape and attached to a partial metal rimmed balance. According to Loseby, this eliminated middle temperature error, and chronometers fitted with such mercury balances won Loseby first in the Greenwich trials for five consecutive years. Interestingly, Gardner finished several of Loseby's chronometers on the latter's death, including two which were given to Loseby's executors. Purportedly, Gardner had contracts to supply chronometers to the Italian, Dutch and Thai governments, and he continued to submit chronometers to Greenwich up until WWI. He also frequently contributed technical articles to the Horological Journal, on various aspects of chronometer function and manufacture.Around 1901, Gardner travelled to Fleurier, Switzerland to meet with Charles Edouard Guillaume, of 'Invar' and 'Elinvar' fame. Gardner successfully negotiated a contract with Guillaume, stating that he, Gardner, would become the only supplier of 'Guillaume balances' in the U.K. and Ireland. The contract specifies that the balances were to be sold for no less than £2 and were to be used in chronometers sold for no less than £25. Unfortunately, the contract was later cancelled through mutual agreement, as Gardner's frequent trips abroad and extensive work at home culminated in a nervous breakdown. Gardner continued to work on his chronometers and the pursuit of 'middle temperature error' elimination, his workshop being moved to the third floor of the house as his eyesight deteriorated. He worked on improving chronometers, particularly investigating palladium springs and five bar cut balance wheels, right up until his death in 1931. A contributor to his obituary noted that 'what he did not know about chronometers was not worth knowing, but at the same time he always had his eyes and ears open for new ideas'. His wife died in 1943.After his father's death, Malcolm Gardner, under the auspices of Courtenay Ilbert, established a horological bookselling business to clear out his father's extensive book collection. Malcolm rapidly became very well-known in the horological world, later dying in 1960. The majority of the books he sold eventually ended up in the British Horological Institute's Library. The current chronometer, No. 5/4186, had a varied service life. It was purchased by the Admiralty in March 1899 for £44. Less then a year later it was used on board a ship bound for Sydney, and it spent more then a year on board. On its return, it was serviced by Usher & Cole; why Gardner did not service it is unknown, possibly he was too busy with manufacture and travel to worry much about servicing. In 1903, the chronometer was used by HMS Merlin, on the ship's maiden voyage to Australia, as part of the Royal Navy Survey Service. The chronometer was collected a year later from Bombay. After another Usher & Cole service, the chronometer was next used in 1907 on the Nimrod as part of Ernest Shackleton's 1907 Antarctic expedition to reach the South Pole. The team, lead by Shackleton, came to within 97 miles of the magnetic pole, before being forced to turn back due to bad weather. The expedition was the first to climb the southernmost volcano, Mt Erebus. A description of the expedition, written by Shackleton, notes that Jameson Boyd Adams, the Royal Navy Reserve Commander and the first to volunteer for the expedition, 'every morning, directly after breakfast, wound up the chronometers and chronometer watches, and rated the instruments'. Which chronometers these were, is unknown.In 1909, the chronometer was returned to the admiralty and again serviced by Usher & Cole. In 1915, the chronometer was installed on HMS M19 a monitor ship seemingly stationed near Turkey during WWI. Shortly after the chronometer was installed, a 9.2' gun on board the ship exploded, causing a fatality and several injuries. The ship was then transformed to a crude oil carrier. The chronometer was returned to the admiralty in 1917. The chronometer was next transferred to the India office in 1920, being sold to said office the following year. The chronometer's movements after this date are unknown.For further information on this lot please visit Bonhams.com

Berner, Mercer Chronometers: History, Maintenance & Repair by Tony Mercer, and Mercer Chronometers by Tony Mercer. 21cms (8ins) wideFootnotes:The paperwork associated with this lot comprises of an extensive, handwritten description of care of the chronometer, as well as an Admiralty service record from Greenwich Observatory. The record states that the chronometer was initially used in Kilindiri (likely an Admiralty base in Sri Lanka) from 1943-1945, before being returned to T. Mercer, presumably for cleaning and any repairs, at a cost of £1 15s. In 1947 the chronometer was installed on the RFA 'Black Ranger' which largely stayed around Devon and Cornwall during this time, with a voyage to Trinidad noted. The ship also managed to rescue a Greek steamer which was cast adrift due to technical issues. The incident made the headlines, but it was shortly after this, in 1951, that the chronometer was returned to Mercer for servicing (at a cost this time of £4 14s) before being installed on the newly built 'RFA Eddyrock'. This ship, and the chronometer with it, spent most of its career around Singapore. Interestingly, the record states that the chronometer was in Singapore in 1957, before being serviced by Graves Antiques, at a service cost of £95. The 'RFA Eddyrock' was bought by a Singaporean company in 1967, so it is reasonable to suggest that the chronometer remained on board the ship through the entirety of 'RFA Eddyrock's' British career. The record states that the chronometer was 'Taken Off Charge' in 1970, though it is not specified what happened to it when it was taken off charge.https://www.historicalrfa.org/rfa-black-rangerhttps://www.historicalrfa.org/rfa-eddyrock-ship-informationhttps://ww2db.com/country/ceylonhttps://discovery.nationalarchives.gov.uk/details/r/C527723This lot is subject to the following lot symbols: Y ФY Subject to CITES regulations when exporting items outside of the UK, see clause 13.Ф This lot contains or is made of ivory and cannot be imported into the USA or any country within the EU.For further information on this lot please visit Bonhams.com

A Fascinating and Unique 19th Century Mahogany Floor Standing Eight-Day RegulatorRecorded by Dr Vaudrey Mercer to be the Arnold Workshop RegulatorThe hood with flat top and ogee moulded cornice over plain sides and square glazed front door lined in a quarter-moulding, the throat with narrow moulding over two trunk doors: the upper being 29.5 inches long with central lock and moulded edge, the lower 16.5inches long with a lock, to a plain apron at the base. The sides of the case plain except for a pair of 5 inch panels let into the sides set at 37.5inches from the pendulum suspension point (presumably evidence of an alternative pendulum being in use at some stage). A small handwritten paper label bearing a fractional number (365/189?) is applied to the interior left-hand side. The 22cms (8.75inch) square silvered brass dial with twin subsidiaries set one above the other; the upper marked in Arabic five-second intervals with inner Observatory marks at the fives, with single blued steel counter-balanced hand. The lower dial with identical markings and now set with a pair of blued steel hands to give hours and minutes. Signed across the centre of the dial Arnold, 84 Strand, LONDON. The weight driven movement with arched plates measuring 22cms x 13cms (8.75ins x 5.25ins) united by five knopped pillars pinned through the backplate (the movement originally had six pillars, although this last was removed in order to make way for a new great wheel), the lower two pillars threaded to accept securing bolts from the underside. Now winding through the front on to a barrel, with Harrison's maintaining power. The great-, centre- and third-wheels all of six crossings, the deadbeat 'scape wheel of four crossings, to a pair of jewelled pallets spanning eleven teeth, the high count pinions unusually made of brass. The long steel crutch with brass fork to an invar pendulum rod terminating in a pair of steel cylinders joined top and bottom and held by a long threaded screw to allow for fine adjustment. The pendulum is suspended from a substantial right angled brass frame secured to a solid mahogany block mounted on the backboard via seven screws, its lower right-angled arms drilled to accept the securing bolts which locate into the two lower movement pillars. With pendulum and small brass weight.Footnotes:Provenance: The private collection of Dr Vaudrey Mercer, and thence by descent. Dr Mercer was confident enough to record this in his exhaustive work, John Arnold & Son, Chronometer Makers 1762-1843 (published in 1972, and updated with a supplement in 1975) as 'The Workshop Regulator'. Five pages and four plates are dedicated to it in Chapter XI, which also includes the seven other known Arnold regulators at that time: John Arnold No.1; Arnold No.2; the Manheim regulator; Arnold No.101; two at Dunskirk Observatory (only one of which is complete); and the Shuckburgh regulator. He suggests that the current pendulum may have been added by Dent, or 'more likely by Frodsham when the business was taken over by them.' Having discussed different aspects of the clock, Mercer delivers the following verdict: '..I think this clock started life as a thirty hour clock with only minutes and seconds hands, and that it was used purely and simply as a regulator in the true sense of the word and almost certainly by John Arnold himself. The dial and eight day mechanism being an improvement on John Roger's part, to save the bother of daily winding, and then perhaps later still the hour hand was added, but still retaining the old dial without any hour numerals.' It is very interesting to note that while the use of two doors on the case trunk is very rare, it is not unheard of – a similar example exists in the collection of the Royal Museums Greenwich, reference number ZAA0534.

Footnotes:Provenance:This clock was the property of William Eve, mayor of Stoke Newington 1902-1903, and could well have been in his family ownership since new. The Holingue family, also sometimes spelt Hollingue, were generational clock manufacturers, whose workshop was thought to have been established by Jean-Baptiste Holingue in Saint-Nicolas-d'Aliermont, possibly in the early 19th century. It was taken over by his two sons, Jean-Francois and Louis, around 1845, or possibly a bit earlier. It appears there was a period when Jean-Francois, presumably the elder of the two brothers, was running the workshop on his own and trading under the name of Holingue fils. This period seems to have begun around 1845, when Holingue fils is mentioned in a civil service journal, and continued at least until 1849, when Holingue fils were awarded a Bronze Medal at the Universal Exposition of that year. The workshop was only mentioned as manufacturing clock movements. It is known that Louis and his partner had a son, Louis Albert, around 1848, which may explain his initial absence from the workshop. It has been suggested that Holingue fils briefly partnered with Emile Martin to form Holingue et Martin, possibly just to exhibit together in the 1851 Exposition. Both workshops were based in Saint-Nicolas-d'Aliermont, but this potential partnership couldn't be verified. By 1855, however, Louis seems to have joined his brother, as the workshop had been renamed to Holingue frères. They were advertising as 'makers of rough movements, carriage clocks, 8-day clocks, alarm clocks, etc.' and reference was also made to the bronze medal won in 1849.A year later, at the 1856 Universal Exposition, they received an honourable mention and seemingly had expanded their offerings to include regulators, chronometer blanks, calendar complications, and telegraph movements. In 1857, they listed their business simply as makers of movements, and this description continued until at least 1864. Whether they had stopped producing chronometer blanks, telegraph movements, etc. or they felt it unnecessary to advertise the breadth of their output is unknown. The workshop did exhibit in the Rouen Exposition of 1857, and their entry was described as a 'perfected movement' which struck the quarters and alarm on a carillon. In 1875/76 Louis Albert, Louis' son, appears to have sold the workshop to Drocourt, which was one of the main firms they supplied movements to. It is likely that this sale was due to Louise Albert not wanting to take up the family workshop; he had married in Paris, in 1870, to Victor Reclus' daughter, Henriette Clarisse Amélie Reclus. As the Reclus family had a workshop in Paris and a home in the Parisian suburbs, it is understandable that Louis Albert would not relish the prospect of taking on a workshop in Saint-Nicolas-d'Aliermont. It remains unknown if either his father or uncle were alive when the workshop was sold. Drocourt continued to supply rough movements to the Holingue frères former customers, in addition to using the old stock in his own clocks.The following firms and workshops are all known to have used movements by Holingue frères: Moser, Paul Garnier, Moise Bollviller, Drocourt, Leroy et Fils, Athanase Bourdin, Dent, and Victor ReclusNormandy Association (1856) Annuaire des Cinq Départements de la Normandie.

A good and rare late 18th century mahogany drop dial timepieceMatthew and Thomas Dutton, LondonThe 13.5 inch signed Roman and Arabic dial with minute track and original heart shaped hands framed by a cast concave brass bezel within a convex moulded surround over shaped side pieces to the drop trunk terminating in a moulded chisel foot with locking door (key present). The substantial single gut (now wire) fusee movement with large plates united by four tapering pillars, the anchor escapement with heavy steel-rod pendulum on a T-bar suspension 66.5cms (26ins) high. Footnotes:A similar wall clock by Thomas Mudge and William Dutton is illustrated in Birch Thomas Mudge and William Dutton, a perfect partnership 2019, page 44.William Dutton was apprenticed to George Graham in 1738, suggesting 1724 as a likely birth year. His father is listed as Matthew Dutton, a gentleman from Marton, Buckinghamshire. William gained his freedom in 1746, possibly marrying Ann Millward a year later, though this is not confirmed. Around 1760, a William Dutton is recorded living in Bolt Court, which was quite near to Fleet Street. Another former Graham apprentice, Thomas Mudge, was living very close to William Dutton. The two eventually entered into partnership, though exactly when is unsure. It seems that for most of their partnership, Mudge was solely responsible for paying the Land Tax, meaning Dutton's name doesn't appear in the Tax books until the 1770's. The earliest proposed date for the start of the partnership is 1750/51, with most sources agreeing that the two were certainly in partnership by 1765, operating out of 151 Fleet Street. Around the time that the partnership was forming, William and Ann had two children; Matthew, likely born around 1757, and Thomas, likely born around 1762, who would both become horologists. The couple would have at least four other children; Sarah, Hephzibah, Nancy, and Dorothea. In April 1771, Matthew Dutton was apprenticed to Thomas Mudge. However, this same year Mudge departed London for Plymouth, to concentrate on his chronometer construction. It appears that Matthew's apprenticeship was turned over to his father at this point, and he gained his freedom in 1779. His younger sibling, Thomas, was apprenticed to their father in 1776, and gained his freedom in 1791. William Dutton managed the business for Mudge and is recorded as being the rate holder for 151 Fleet Street, beginning in 1772. By 1774, Dutton had moved the premises to 148 Fleet Street, though the shop continued to be called Mudge & Dutton. Around this same time, Mudge began submitting chronometer's to the Board of Longitude, and Matthew Dutton appears to have acted as a go between. He would deliver the chronometer to be tested to the Observatory, taking it apart to demonstrate Mudge's modifications, monitor it when it was on test, and then communicate to Mudge any questions or rulings from the Board. Interestingly, Mudge Jr. noted that the 'Green' and 'Blue' chronometers were delivered to 'Mr. Dutton' in 1790 and had since remained with the Duttons. When, and under what circumstances, the chronometers left 148 Fleet Street, remains unknown.William Dutton died in 1794, having left all the tools, engines, and utensils of his trade to Matthew and Thomas. He also left the shop and, presumably upstairs, apartment to Matthew, and the adjoining apartment to Thomas. Thomas Mudge also features heavily in William's will, being left one-third of all William's estate, land, and tenants in Bedford, the other two-thirds to be shared by Matthew and Thomas. The three horologists were also appointed his executors, as well as the appraisers of all the stock in his shop, with the option of appointing additional appraisers, should they see the need. Money was also left to the other four children, as well as a small annual pension to be paid to Elizabeth Dutton, and her daughter Caroline. It seems quite likely that Elizabeth and Caroline Dutton where the wife and daughter, respectively, of Benjamin Dutton, William's nephew and a horologist. He was apprenticed to John Holmes in 1755, though it is unclear when he gained his freedom. Interestingly, it has been suggested that John Holmes was one of the first manufacturers to supply 'Mudge & Dutton' with movements, before Holmes moved out of the area around 1760. Benjamin died in 1786, leaving everything to his wife Elizabeth.William Dutton also left some money to Thomas Mudge and John Priest, another of Graham's former apprentices, to thank them both for their firm friendship throughout the years. It appears that William's wife, Ann, died in 1787, the same year that the majority of William's will was written. It was updated in 1792, to include leaving some money to his daughter in law Katherine, who appears to have been Matthew's partner (possibly Catharine Dunant), and his future grandchildren. As there was some confusion regarding the validity of this amendment, Thomas Mudge and James Bullock, a Holborn clockmaker and long-time friend, both appeared in person to swear to the amendment's validity. Matthew and Thomas entered into partnership together, operating out of the 148 Fleet Street premises. Oddly, the 1794 entry lists 'M. & J. Dutton, watchmakers' working out of this address. It is possible this was a misprint for 'T'. Matthew and Katherine would have at least four children; Louisa, Catherine, Matthew, and Jane. Of these, only one would go on to be a horologist; Matthew, who was apprenticed to his father in 1799.In 1802, two years after Matthew (Sr.) had been made Master of the Clockmaker's Company, the partnership between Matthew and Thomas was mutually dissolved, with notice given that Matthew Dutton would be continuing the 148 Fleet Street business alone. It is not known what happened to Thomas; he isn't listed as a horologist in any trade directory for London, Plymouth, or Buckinghamshire after the dissolution. It has been suggested that he married Sarah Kingdom in 1794, and that one of their children, Thomas (Jr.), became a Captain with the Royal Navy and eventually emigrated to Tasmania. However, this has not been independently confirmed, and still doesn't clarify what Thomas (Sr.) was doing after 1802..For further information on this lot please visit Bonhams.com
