History: According to the repair books this watch was returned for overhaul on 22 June 1830 and 20 October 1835 at the request of a Général Sebastiani of 55, Rue Faubourg St. Honoré, Paris. Note: This watch is certainly one of the earliest known by Breguet with a jump hour hand; furthermore it would appear to be one of the first to strike on gongs. Breguet is reputed to have been the inventor of the spring gong, although he never claimed it himself but certainly used them. The gong represented a considerable advance over a bell housed in the back of the case, as it took up much less space, could be made in different shapes and therefore fitted into far thinner watches. Different lengths giving a different tone also allowed for a clear distinction to be drawn between the striking of the hours and the quarters. The first watches of this type had the gongs fitted on the inside of the case; fitted to the back plate they allowed the movement to have a smaller overall diameter. In fact this watch appears to be one of only two examples with the gongs mounted on the back plate.
