Exhibit P18.According to the exhibition, the movement came from Joseph Preston, who was working out of Prescot. Joseph Preston were well-known watch and chronometer movement manufacturers and their mark 'J.P.' was considered a hallmark of quality. Although based in Prescot, they formed a key link in the national supply chain that saw parts made largely in the North of England, and the West Midlands and assembled into a rough movement, before being sent to London for finishing and sale. A sizeable part of Preston's client base was in London, and to a lesser extent, Coventry.The firm was founded by Joseph Preston in 1829 at 19 Eccleston Street Prescot, and renamed 'Joseph Preston and Sons' in 1840, when his sons Thomas and Joseph began working there full time. In 1891, at the age of 16, the Prestons' nephew, Harry Pybus, began working in the shop. He worked at, and learnt, the twenty separate trades employed in the shop, that resulted in a complete, unfinished watch or chronometer movement. Pybus took over the shop on his uncles' death, though he kept the name 'Joseph Preston and Sons'. During the second world war, it was noted that, having no other employees, Pybus managed to make several two-day chronometer movements entirely on his own, in a shop which lacked electricity. He would run the shop for nearly sixty years, until his death in 1952; anecdotally he was said to be in the middle of cutting watch escape pinions when he died. In his obituary, he was hailed as 'the last of the old Prescot watchmakers'. The shop was demolished shortly after, making Joseph Preston one of the last independent horological manufacturers to shut in Prescot, and area long famed for supplying high-quality movements.The firm supplied a large range of movements to a varied customer base, which included Mercer, Kullberg, and even Patek Phillipe. William crisp was another regular customer. The Hartnup balance was developed by John Hartnup, the first director and founder of the Siderial Liverpool Observatory, established in 1843. The Hartnup balance corrects for middle-temperature error in chronometers. The middle temperature error refers to the error produced in standard compensation balances: The balance is designed to account for an extreme high temperature error and an extreme low temperature error, however, between this range the chronometer gains a bit, and loses a bit when exposed to temperatures outside this range. This means that when a chronometer is exposed to a wide range of temperatures the rate will change much more then when the temperature exposure range is small.Hartnup's solution, likely created around 1847 and actually made by William Shepherd of 13 Bath Street Liverpool, involved laminated cross-bars connecting a fairly standard compensation rim; the outer rim would compensate for extremes and the inner cross-bars would moderate the middle temperature. Hartnup did not patent this balance, partially as he was eager to see it taken up by many makers as an improvement in timekeeping generally, but also because he didn't think that, as a Director of the Observatory, he could profit from work done during his tenure. The balance was never widely adopted, not least because it took twice as long to manufacture as a standard compensation balance did, meaning that chronometers with a Hartnup balance are quite uncommon.

A fine and rare second quarter of the 19th century gilt brass carriage timepieceJames F. Cole, No. 1 Maddox St., Regent Street, LondonThe case surmounted by a stylised facetted Greek key handle with four ribbed mushroom finials above slender Doric columns to octagonal feet, the sides, top and front panels all engine turned, the rear panel patinated and with rotating winding shutter. The 1.75-inch engine-turned silvered Roman dial with subsidiary seconds and slender blued steel moon hands reading against the finely textured centre. The going barrel movement with underslung English lever platform escapement, cut and compensated bimetallic balance, the backplate signed James F. Cole No 1 Maddox Stt Regent Street. 13cms (5ins) highFootnotes:Based on the address on the backplate, this clock was likely made between about 1829-1835. James Ferguson Cole was born around 1798 in Nether Stowey, Somerset to Catherine and James Cole, the latter of whom was a clockmaker, and known throughout the village as 'Conjuror Cole'. It also seems that the family were personally acquainted with both William Wordsworth and Samuel Taylor Coleridge. The Coles had two more children after James, Thomas (born around 1800) and Elizabeth (born around 1808). Both James Ferguson and Thomas became clockmakers, presumably being apprenticed to their father, with evidence that at least James Ferguson began his apprenticeship at 11 years old. According to some sources, James Ferguson was named after the self-taught Scottish astronomer of the same name, who published books and travelled Britain explaining the concepts of Astronomy to lay people. He also made orreries and clocks, eventually becoming a Fellow of the Royal Society. James Ferguson Cole certainly lived up to his namesake and became renowned for his mechanical skill and dexterity; he took out his first patent, for a form of pivoted detent escapement, at the age of 23. Thomas Cole would be lauded for his fine cases and dials, though does not seem to have achieved the same mechanical superiority as his brother.The Cole family moved out of Nether Stowey in 1811, eventually settling in London by 1818. Clocks are known from James Ferguson beginning around 1821, when he seems to have established his own premises, seemingly working out of Hans Place, Chelsea. There is some confusion around this address, it is possible this was the family home. Later in 1821, though, Cole moved to 10 Park Lane, Piccadilly. It does also seem that both brothers were making clocks beginning in their mid-teens, though this was likely done as part of their apprenticeship.Beginning in 1823 the brothers formed a partnership at 3 New Bond Street and began making clocks together. They were responsible for producing some of the most complicated carriage clocks available, which included standard complications such as moon phase and days of the week, and more advanced complications such as perpetual calendar and daily times for sunrise and sunset. They also made watches and chronometers at this time. It is unclear when the partnership dissolved, or why, with the date of dissolution being variously given as 1829, up to 1832. James Ferguson's first shop, after Thomas Cole's departure, was located at 1 Maddox Street, Regent Street, where he stayed until about 1835, then moving to 9 Motcomb Street, Belgrave Sq. Throughout this period he advertised as a chronometer and clock maker. Around 1846, he moved again, this time to 30 Granville Square. At some point, possibly around the time of his move to Belgrave Sq. or a bit after, he married Charlotte Wyatt. The couple would have four children together: James Ferguson Cole Junior, Mortimer George Cole, Ada Martha Cole, and Jessie Cole. Both James Ferguson Junior and Mortimer would become horologists. Ada was a painter, miniaturist, and lithographer who exhibited her work at the Royal Academy. She also printed lithograph portraits, most well-known being of the chronometer maker William James Frodsham. It is unclear if she was or was related to the photographer Ada Cole, who was an early campaigner for animal rights. Cole continued to make high-quality, complicated pieces, relocating first to 20 Devonshire Street and then 11 Great James Street during the 1850's, while his place of residence remained 5 Queen Square Bloomsbury.James Ferguson became quite involved with the British Horological Institute from the beginning, becoming Vice President in 1859. Through his involvement, professional watchmakers began to share information with each other, when previously they had kept the most inconsequential of workshop procedure to themselves, fearing competition from others. For decades afterwards it would be said that 'he broke the ' Conspiracy ' of secrecy' amongst watchmakers. Despite this he relinquished the post in 1862, having become sick of the continual bickering and politicking at council meetings. Another BHI member, however, suggested that it was Cole's 'peculiarity of temperament' which caused the unrest during the meetings. Regardless, in 1875, Cole was commissioned by the BHI, for the sum of £100, to write a series of articles which, taken together, would form a Treatise on Isochronism. It was said that this was partially done to prevent the still new British Horological Institute from appearing antagonistic towards Cole; his possibly forced resignation was warned as being 'no compliment to such an eminent man and also bad taste'. The reviews of the Treatise, after it was published in 1877 were mixed with some members commenting it 'was difficult to criticise [the Treatise] because it contained more language than fact' and others protesting Cole's assertion that flat watchsprings demanded on overcoil if they were to keep accurate time. Some defended the Treatise, including a watchmaker named Joyce Murray, who had been practicing for over three decades. Murray claimed that Cole's Treatise was 'the most valuable work on the subject extant'. Murray further stated that 'Had it been published 30 or 40 years ago, when we began to adjust lever watches, the saving of time and mental labour would have been enormous.' This might suggest that politics and personality clashes biased some reviewers.Cole refused to debate the merits of his Treatise with the various BHI members. He died shortly after, in January 1880, though he continued to practice his horological skills until a few years before his death. James Ferguson Jr. moved into his house, Belvedere (later Tower) House, Bexley Heath, and lived there until 1935. In his obituary, James Ferguson Cole Snr.'s, it was noted that he was one of the foremost practical horologists of his time, and in his particular field of study (springing and timing) he was without equal. Paul M. Chamberlain was well-acquainted with James Ferguson Cole Junior, and his summary of James Ferguson Cole Snr. is probably the most apt: 'Exemplary in his private life, a devoted husband and father, brilliant as artist and scientist, he was in every way fitted to rank with the illustrious men of his time.'Good, R.

A rare mid-19th century French carriage clock with chaff cutter escapementPaul Garnier, Paris number 2976The early multi-piece case with facetted handle over a bevelled glazed inspection panel (the repeat button passing through the glass), moulded uprights and a plinth base, the solid rear door with hinged shutter opening to reveal the winding and setting squares. The Roman white enamel dial with minute track and numerals picked out in light and dark blue, the centre signed Paul Garnier Hger de la Marine Paris, above blued steel trefoil hands and a subsidiary Arabic alarm dial with blued steel setting hand. The three-spring barrel movement with Garnier's own chaff-cutter escapement with three-arm monometallic balance, and extremely delicate arbors throughout, rack striking the hours and half-hours on a bell. The back plate signed Paul Garnier Paris, and numbered on the backplate under the bell, the rear door, shutter and base also repeat numbered. Ticking, striking, sounding the alarm and repeating. Together with a double-ended winding key. 18cms (7ins) highFootnotes:Paul Garnier (né Jean-Paul) was born in 1801 in Épinal, France, moving first to Luxeuil to carry out a watchmaking apprenticeship, and then to Paris in 1820 to join Lépine's workshops, before finally establishing his own business in 1825. In the 1827 Exhibition he exhibited an astronomical clock and some mantel regulators, which won him a silver medal. He would win silver medals again at both the 1834 and 1839 Exhibitions, before winning a gold medal in 1844. Around this time, he seems to have written to the formidable Antide Janvier, asking for permission to use the title 'Elève de Janvier', as Garnier, at some point, attended the free Horological school Janvier established in 1802. Janvier readily assents to this request, and Garnier used the title on his carriage clocks until about 1835, and in his written correspondences until at least 1844. Around 1835, Garnier makes use of the title 'Horloger (or Her) du Roi', which in turn is supplanted by 'Her De La Marine' after the 1848 revolution and the deposition of the monarchy.From 1830 Garnier began to make affordable, semi-massed produced carriage clocks (pendules de voyage) and could be said to have established the Parisian carriage clock industry. He was able to do this by combining a basic, easily made design with his patented 1830 escapement. This escapement, alternatively called the 'chaff-cutter', 'Gautier', or 'chopper', could be machine made, drastically reducing the time and cost of making. It is a type of frictional rest escapement, comprising of pallets in the form of a single roller (a circle with about 4/9ths of its circumference cut off at an angle and the sides ground) made of either jewel or hardened steel, the latter being more common with repaired rollers. The escape wheel is in fact two separate wheels mounted on the same arbor a specific distance apart. The wheel teeth are bevelled along the edge that interacts with the roller.The combination of basic shape and cost saving escapement meant that pendules de voyage, having previously been economically unattainable to the vast majority of people, were reduced in cost to the price of a standard mantle clock.Despite being affordable, these clocks were not poorly made, exhibiting very fine diameter pivots (even by French clock standards) and usually having rack striking, which was a desirable feature, being much easier to set than count wheel striking. The clocks would also only strike the half hour and the hour, which saved on cost compared with the more common repeaters. In the early clocks, engine turned dials, one-piece cases, and barrel stopwork were all very common. With clocks made between 1830-1840, it was common to fit a coloured-paper covered block of wood into the base of the hollow casting.In addition to carriage clocks, in 1847 Garnier presented a novel master clock and slave clock system, and at least one chronometer has been assigned to him. He also pursed scientific instrument making, his obituary eventually being published in the Society for Civil Engineers bulletin in 1869.His son, also Paul Garnier, was born in 1834 and continued the business after his father's death. Additionally, he submitted drawings and models of his father's design for a free-sprung chronometer escapement to the Conservatoire National des Arts et Métiers and the Revue Chronométrique. Before his death in 1916, he donated his family's collection of watches and clocks (the former including examples from the 16th century) to the Musée des Arts et Métiers.R. A. E.

A unique and extremely interesting late 18th century ebonised longcase timepiece with additional counting featureWright, PoultryThe hood with serpentine arched cresting supported on freestanding brass-mounted Doric columns, with gilt-heightened gothic-arched glazed side doors over an elaborately stepped and moulded throat section, the long arched door with gilt-heightened raised moulding over a conforming stepped moulded section to the plain base on shaped apron. The 12-inch one-piece silvered arched dial centred by a Roman chapter ring with matching pierced blued steel hands, wound at VI, surmounted by a series of four subsidiary dials - the furthest to the right-hand side set with two hands simply giving running seconds and the hour in a 24-hour day. The remaining three are directly geared and mark the passing of each individual hour, their dials marked as 100; 1000 and 20,000.The large weight driven movement with plates measuring 21.5cms x 18cms (8.25ins x 7ins) united by four substantial knopped pillars, the large diameter barrel driving a four wheel train terminating in an anchor escapement set to the top right hand side of the plates, directly behind the subsidiary seconds dial, the plain pendulum suspended from a centrally-mounted cock, thereby necessitating a pivotted right-angled linkage to the crutch. Together with the pendulum with steel rectangular-section rod terminating in a brass bob, later crank winder, case key and brass-clad weight. 2.07m (6ft 10ins) highFootnotes:Thomas Wright was born around 1744 and was made Free of the Clockmakers Company in 1770, establishing himself in the Poultry likely at number 13, and moving later to number 6. At some point between 1770 and 1781, he was appointed watch and clockmaker to the King, though how he obtained this distinction is unknown. Around 1781, Thomas Earnshaw approached Wright to finance his patent for a detached spring chronometer escapement, the former having previously had a falling out with his previous financer. After much discussion, it was decided that Wright would file the patent on Earnshaw's behalf, and Earnshaw would recompensate Wright the 100-guinea patent fee, by charging an additional guinea for each of the first 100 chronometers sold. The patent, 1354, was filed by Wright in 1783. It has been claimed, by Earnshaw, that Wright insisted these first 100 chronometers bear the stamp Wright's Patent on the movement. One such chronometer is known which carries this stamp, though the others seem to use T. W. Pt. 34, with the T.W. presumably standing for Thomas Wright. In 1784, Earnshaw developed a bimetallic compensation balance, and the first watch this was used on was signed Thomas Wright in the Poultry, London, No. 2228. Thomas Earnshaw was not the only famous colleague Wright had, as he also worked with Matthew Boulton, of Lunar Society fame, beginning around 1770. Boulton and Wright produced a clock for King George III in 1771; Boulton supplied the gilt bronze and Blue John case, while Wright supplied the movement. It is possible that this is how Wright received his Royal warrant, though why Boulton contacted Wright in the first place is not clear. Although the clock was made for the King, the design was used by Bolton to manufacture at least six other 'King's clocks'. The escapement was originally verge but was replaced with a pin wheel in the 1820's by Benjamin Vulliamy. Wright is known to have had at least one child, George William, who was apprenticed to his father in 1785. Unfortunately, Wright died in 1792 on a visit to Birmingham, possibly to meet with Boulton, and his son does not appear to have been made free. There also does not seem to be a record of a 'George William Wright clockmaker' and it is possible he pursued a different career after his father's death. There is some indication that Wright's shop was taken over by a horologist named Thorp and the shop name became 'Wright & Thorp', though this hasn't been confirmed. Watches from Wright seem to be more prolific than his clocks, though some of Wright's work can be found at the Palace Museum in Peking.There was also a Thomas Wright of Fleet Street working between 1718-1748 as a scientific instrument maker. This Thomas Wright was also Mathematical Instrument Maker to His Royal Highness, George, Prince of Wales and famed as one of the best instrument makers of the day. Whether this was a relation of Thomas', possibly his father, remains unknown.Weaving, A. H. (1991) 'Clocks for the Emperor', Antiquarian Horolgy, Vol. 19 (4), pg. 389.Randall, A. G.

A very rare second quarter of the 19th century boxwood-strung ebonised travel timepiece with alarm and quarter repeatWestwood, Princes Street, Leicester Square, LondonThe arched case surmounted by a recessed folding campaign-style brass handle over a ripple moulding to the top and bottom, with geometric boxwood line inlay, supported by four brass ball feet (the two rearmost spheres with flattened backs). The 4inch signed white enamel Roman and Arabic dial with Breguet style hands and tapering alarm-setting hand, within a cast concave bezel and with three blued steel hands. The movement consisting of three brass plates united by plain turned pillars, the front pair housing the going train with maintaining power to a chain fusee terminating in an English underslung lever escapement set below a heavy plain brass balance with three timing screws; the alarm and repeat trains both set within the rear pair of plates, the former with brass double-headed hammer acting on a large bell above, the hours and quarters repeated via one large and one small brass hammer sounding on a single bell set on the top plate. All the wheelwork protected by pinned side doors and a screw-on rear plate signed Westwood, Princes Street, Leicester Square, LONDON with silvered regulation dial above. Ticking, repeating and alarm operational. With handle recessed 23.5cms (9.25ins) high; 28cms (11 ins) high with handle raised. Footnotes:Robert Westwood was born in 1784. Although there is no record of his apprenticeship, there is a James Westwood who was apprenticed to William Rose in 1771. James was from Westminster, and his late father, John, had been a solicitor. Given the dates, it has been suggested that this James Westwood was Robert's father, the latter taking his son as an apprentice when he was old enough. In 1818, Robert married Mary Priestman, who was about 22 years his senior, and promptly moved in to 23 Prince's Street, a leasehold property she owned. They went into business together; Westwood was responsible for the watches and clocks, and Priestman managed the jewellery side of the business. It is unknown if she had served an apprenticeship as a jeweller, or possibly was taught by a relative. In July 1822, the property was burgled by William Reading who stole 200 watches, with a combined value of £600, 10 watch chains, with a value of £20, and a number of miscellaneous items and some money. The total value stolen, including the watches and chains, was £652, which suggests that the couple had quite a prosperous business. The burglar apparently had a history of petty theft, though this was the first time he had been caught and prosecuted for it. He was eventually found guilty and executed. In 1824, a trade card was produced for Westwood, which showed he was still trading from 23 Prince's Street and also described him as a 'chronometer, watch and clock maker'. The card also referred to the recent, 1821-1823, Polar Expedition of William Parry, stating that the only two chronometers on the expedition which ran without fail were owned by the voyage's two surgeons, and were manufactured by Westwood. The card also claimed that several officers for the current 1824-1825 expedition had requested Westwood chronometers.Five years after the trade card was published, Westwood took out a patent for an eight-day pocket watch. The larger barrel was accommodated by splitting the train over two planes, which meant that the watch would be no larger than a standard pocket watch. This idea was used throughout the 20th century to make increasingly smaller and more delicate wristwatches, which would still run for the standard 30 hours. The Duke of Sussex, Augustus Frederick, was so taken with Westwood's eight-day watch that he had one commissioned. It was sold at auction, after his death in 1843, and was described in the catalogue as being in a gold, engine-turned case, and numbered 50. It was bought for £38 10s. This was the only device of Westwood's in the Duke possession, suggesting it was a one-off commission, however, Westwood would style himself as 'Watchmaker to His Royal Highness the Duke of Sussex' throughout his career.Around 1829, Westwood had relocated the business to 35 Prince's Street, which was larger, and located opposite St. Anne's church. In 1833, another trade card was printed, with one side describing the use of Westwood's chronometer on the Polar expedition, and the other side announcing him as watchmaker to the Duke of Sussex. A watch paper from around this time also announces his Royal appointment, while still describing him as a chronometer, watch, and clockmaker. The bottom edge of the paper reads 'Watches & Clocks of Every Description Cleaned & Repaired.' In September 1836, despite the change of premises, the shop was again robbed. The burglar, Sarah Moore, was charged with breaking and entering and stealing a watch worth £30. She pled guilty and was transported to New South Wales in December.Westwood was reported in the newspapers to have quite a temper, particularly when it came to clients. One merchant ship captain came into Westwood's shop to complain about the timekeeping of his watch (possibly a chronometer). The argument grew quite heated, and Westwood eventually reached over, grabbed the timepiece from the captain's hand, smashed it to the ground, and 'stamped on it with great violence'. Westwood was taken to Marlborough Street Magistrates Court and forced to pay the captain the full sum of the timepiece. A different client once returned a watch which wasn't running properly. He requested either a monetary refund or a replacement watch. Westwood responded by taking out a pistol from under the counter and threating to 'blow out the young man's brains' if he didn't leave immediately. Again, he was summoned before the Magistrates, this time being fined for the threat of violence.After the second break-in, Westwood took to sleeping in a back room of the shop, in order to prevent another robbery. His wife, whose health was beginning to deteriorate, slept on the first floor. In the early morning of Monday 3 June 1839, Westwood was brutally murdered during another robbery. In total, around 91 watches were stolen, as well as some money from the shop; all the goods and currency were estimated to be worth about £2,000. It seemed that the thief was knowledgeable about watches, as only the very best were stolen, the cheaper watches being left where they were. It was also suggested that the person would have to be familiar with the shop, as some of the watches and money were removed from special hidden drawers in a desk, which a stranger was unlikely to know about. The residents at the time were Mary Westwood, their servant, Maria Pretty, and a lodger of about 10 years, M. Gerard who was estimated to be in his mid-70's. Two lodgers, the Stephensons, had left about a week before, with reasons for departure variously cited as marital breakup or the Westwoods taking exception to their loud and frequent rows. Westwood also employed a journeyman, James Bannister, who lodged elsewhere. In December of the same year, Mary Westwood died of heart complications. At her inquest, the coroner commented that he was surprised that her husband's killer(s) had not yet been caught. As far as can be determined, no formal arrests were ever made. One witness suggested that the robber(s) must have known about watches and would therefore have tried to sell the stolen goods in Holland. Another suggested that friends/associates of William Reading, the first burglar, killed Westwood out of a sense of revenge for their executed confederate. Yet another suggested that the culprit(s) may have been sailors; they would be familiar with Westwood through the chronometers on board and would have a ready-made getaway if they were shipping out directly after the murder.

Surmounted by a low shaped handle over a bevelled glass inspection panel and brass-mounted cornice over bevelled glass side panels and a rear door with pierced brass sound fret backed in green silk, the four corners of the moulded base inset with substantial brass infills. The 4.5-inch square signed silvered Roman and Arabic dial with fancy blued steel hands and subsidiary alarm-setting dial at VI. The triple chain fusee movement filling the case, all wheels of five crossings and wound from the rear, chiming the quarters and striking the hours on three blued steel coiled gongs, each mounted on its own block, the going train terminating in a gilt platform with foliate-scroll engraved cock, the cut and compensated bimetallic balance with 16 gold timing screws set on an overcoiled hairspring.

Together with the original velvet-lined travel case, the silk lid stamped in a gilt strapwork cartouche Barraud & Lunds, 14 Bishopsgate St, Cornhill, with the original winding key set in a recess to the base. Ticking, striking, chiming and repeating. 25cms (10ins) high.Footnotes:Francis-Gabriel Barraud was born in 1727 and was a watchmaker by trade. With his elder son Paul Philip, born in 1752, and younger son John, he would establish the Barraud horology firm. By 1782 they were established in Fleet Street and were listed in trade directories simply as 'Barrauds'. Paul Philip seems to have focused on clocks, as several orders for movements by Thwaites are found in his name only. Shortly after this point, in 1795, Francis-Gabriel died, and Paul Philip took control of the firm. By the end of that same year, Paul Philip had entered into partnership with another horologist, George Jamison, and they began to manufacture chronometers. Initially Mudge-type chronometers were attempted, but by 1797, they began making Arnold-style chronometers, along with a very few being made with an Earnshaw escapement. Around this time, possibly a bit later in 1798, the business relocated to Cornhill, and by 1800 the partnership between Barraud and Jamison was officially moribund, as Jamison has set up his own premises. Three of Paul Philips children, Frederick Joseph, born 1785, John, born 1790, and James, born 1793, were apprenticed to their father and all gained their Freedom of the Clockmakers' Company, as their father had in 1796. In 1809, the oldest child, Frederick Joseph, joined his father in partnership of the firm, followed by John in 1814, at which point the name of the firm is changed from 'Barrauds' to 'Barraud & Son'. When Paul Philip died in 1820, the firm was jointly taken over by Frederick Joseph and John, until 1838, when John Richard Lund, born 1805, joined the firm as a partner. The name of the firm was changed that year to 'Barraud & Lund'. James Barraud did not pursue a horological career after gaining his freedom, instead buying a partnership with a coal merchant in Whitefriars, later also pursuing gentleman farming in Hertfordshire beginning in 1854 until his death in 1876. In 1840, John Barraud died, followed by Frederick Joseph in 1859. The firm continued as 'Barraud & Lund'; Lund partnered with Hilton Paul Barraud, John Barraud's son, born in 1819 and apprenticed to John who eventually gained his freedom in 1846. John Richard Lund died in 1868, and by 1869 his son, John Alexander Lund, born in 1836, was made a partner with Hilton Paul Barraud. After Hilton Paul's death in 1880, John Alexander's brother joined him in the firm. John Alexander died in 1902 but the firm would continue under the control of various members of the Lund family, until it was officially dissolved in 1929.It is interesting to note that John Richard Lund was apprenticed to one of the Pennington horologists. Robert Pennington worked with Thomas Mudge Jr. trying to mass produce Mudge Sr. chronometers.

Breitling - A gold plated on steel 'Navitimer' wristwatch, circa 1964, model number 806, serial number 978312, the signed circular 'reverse panda' dial, 38mm diameter, with twin jet logo, gold coloured batons and hands and gold coloured chronograph sweep, three 'small size' subsidiary dials recording running seconds and chronograph minutes and hours, outer tachymeter scale and bi-directional slide rule with milled edged bezel, signed mechanical crown wind chronometer rated 17 jewel Venus 178 movement, import code 'WOG', (for Wakmann), case, 40mm diameter, gold-plated with start/stop and reset pushers above and below the liveried crown, verso steel, snap on, signed and numbered 806, interior numbered 978312, to a signed black leather padded strap with white stitching and liveried steel pin buckle One of watch-making's most important historic chronograph models, the original 806 Navitimer set the template for modern technical pilot’s watches. Billed as a wrist-sized computer when it was first developed in 1952, the rotating bezel had the ability to compute distance travelled, flight time, airspeed and remaining fuel consumption, due to the integration of a slide rule.In 1956, Breitling introduced the Venus 178 manually-wound chronograph movement which would continue to be used until the early 1970s. Eight years later, Breitling changed the dial layout of the Navitimer, most likely adapting to changing tastes and increasing legibility in low-light conditions. The now-iconic “reverse panda” configuration with black dial and white subdials was introduced in 1963 and in 1964 - the bezel edge changed from a bead edge to a milled edge. Another stylistic change was the introduction of the “twin jet” logo, with ‘Breitling Genève’ below.With the majority of cases produced in stainless steel, a small number were produced with gold-plated cases, and an even smaller number in 18ct gold.The iconic Breitling Genève Navitimer 806 still remains today near the top of virtually every vintage watch collector's wish list.
