This watch features three of the most difficult complications to produce on a watch. The perpetual calendar displays the day, date and month. This difficult to produce mechanism will account for leap years and both shorter and longer months. Once properly set the perpetual calendar will not need adjusting for many years. The perpetual calendar on this watch is also combined with a moonphase. As the name suggests this displays the current phase of the moon in the sky. Where this may be considered one of the least useful functions of a watch, it allows the manufacture to show their artistry and skill in producing fine and complicated watches.The final complication on this watch can be viewed in the form of a tourbillon through the back of the watch. The tourbillon was first invented in 1795 by Abraham-Louis Breguet. The tourbillon was designed to counter the effects of gravity on pocket watches by placing the escapement and balance wheel within a rotating cage. This mechanism is found in watches by only the highest of skilled watchmaker's due to the difficulty to produce. All these complications come together in this fine watch.
