This watch was clearly completed, cased and fitted with a dial circa 1810. The movement of much smaller diameter is to be compared to those produced in the 1780s by Jaquet Droz in Switzerland for the Chinese market. In order to meet the fashion for much larger watches, it has been fitted in a large gilt metal ring onto which the repeating gongs are screwed. The straight line lever escapement is of the type used by Breguet on his watches circa 1810. According to the monogram engraved on the winding weight and the back of the case, and the signature on the movement and dial, this watch could have been completed in Breguet’s workshop to meet a special request. The case was made by Guillaume Mermillod, who was working for Breguet at the time and the movement could have been found unfinished after the French Revolution.
