French brass early small coach clock with alarm Circa 1760

Early small coach clock with cylinder escapement
–
An interesting, early small coach clock with alarm, made by Joseph Silvestre in Paris, France, circa 1760. The case of this watch was crafted from brass and features a back covered with ray skin, a bell and a rim with sound openings. The white very well preserved Louis XV enamel dial features an outer track with Arabic 5 minute numerals, Roman hour numerals, the probably original hands and an iron hand for the alarm. The numbered, excellent quality and very fine movement is fitted with a cylinder escapement, two barrels for movement and alarm, one barrel wonderfully engraved and a fire gilt plate.
The dial and movement are signed.

The item presented here is an interesting restoration object as the movement is intact, but needs cleaning. Additionally the alarm needs to be overhauled and the glass is missing and the ray skin is incomplete. The movement is of exceptionally fine quality for a coach clock of this period.

Silvestre
This is probably a watch made by Joseph Silvestre.
He was an employee of Julien Le Roy before establishing his own independent workshop as a Master in Paris in 1755.

Silvestre remained active in Paris until at least the late 1780’s, contributing to the “Golden Age” of French horology before the industry was transformed by the French Revolution. Following his demise (likely around the time of the French Revolution or shortly after), there is no historical record of a large scale commercial “brand” continuing under the Silvestre name after his death, which was typical for independent 18^th century master watchmakers.
