COACH WATCH Jull.n Le Roy AParis Ca. 1750



Signed: Jull.n Le Roy AParis
Circa 1750

The spring-driven, 25-hour going movement of this coach watch is constructed between two gilt brass plates. The going train has a spring barrel, chain fusee and anchor escapement with balance and balance spring, whilst the hour striking train indicates the hours on a bell and the separate quarter striking indicates the quarters with a double stroke on the same bell. On the hour first the quarters are struck, followed by the hours. Going, striking and quarter-striking trains are driven by springs in spring barrels. The striking train barrels are beautifully engraved. The watch has trip repeat, which is activated by a button near the VIII (grande sonnerie). The finely pierced balance cock covers the balance entirely. Around the edge of the backplate is the regulation disc, the winding arbors and the signature: Jull.n Le Roy AParis.

The white enamel dial has a Roman chapter ring with Arabic five-minute and minute divisions. The time is indicated a fine pair of pierced gilt brass hands. The rear side of the dial is marked with the initials D et D, probably of the enameller.

The partly pierced silver case is embellished with engravings, in which flower and leaf motifs can be recognised, surrounded by swags. The dial is protected by a convex glass in a silver bezel. The rear side shows three winding holes. The movement hinges at the top of the case and is secured with a catch near the VI and after unlocking can be turned outwards. The case has a gimballed pendant. The watch case fits into shagreen covered silver outer case with sound holes, which can be opened by pressing a button in the rear half.

The maker
Julien Le Roy (1686-1759) was born in Tours where he made his first clock at the age of 13. In 1699 he moved to Paris, where he honed his skills as a clock and watchmaker. In 1713 he became master clockmaker and shortly after he was sworn in a member of the guild. He was an excellent watch and clockmaker, who managed to become Horloger Ordinaire du Roi of Louis XV. He was the father of Pierre, who later carried out important work in the field of chronometers.
