Note: Certainly produced between 1785 and 1787 and made at the same period as the very first series of large palpetuelles, this watch is characteristic of the finest early work by Breguet. The case, by Mermillod, who also made the cases of the early perpetuelles, is very si milar as well, and the white enamel dial is typical of the early examples made with Breguct numerals, with "star" minute divisions, and the five minutes marked by a stylised flour de lys. The movement carries on the dial plate the signature: Breguet a Paris, never used by Breguet after 1793. Of full plate calibre with cylindrical pillars, and going barrel it is one of the earliest lever escapements ever made by Breguet, having no pallet jewels, but slotted scape wheel teeth for oil retention. The caliber is also inverted, having the balance on the front plate beneath the dial, and the back plate is relieved for the escapement. Although it is only fitted with a single barrel instead of two and without the winding weight, it is a very similar caliber to that used for the perpetual. IL is also one of the first ever made with jumping hour hand. The ten minute repeating work, although preferred by Breguet to the half quarter, very few watches only were made with it, in particular with the possibility of adjusting the striking speed by means of a small lever in the dial plate.
