POCKET WATCH Abraham Yver Angolesme Ca. 1675 France
Signed: Abraham Yver Angolesme
The spring-driven, 24-hour going movement is constructed between two gilt brass plates, connected by shaped pillars and consists of going and alarm trains. The going train has a spring barrel, chain fusee and verge escapement with a brass hairspring balance under a pierced and engraved cock. The alarm barrel is finely pierced and engraved. It is regulated with a blued-steel pointer on a graduated scale. Near the balance is a blued-steel worm-wheel arbor with a brass wheel to set up the main spring of the going train. The alarm hammer is positioned between the plates. The maker has signed the watch on the outer rim of the backplate Abraham Yver Angolesme.
The engraved silver dial has a Roman chapter with half hour markers. In the middle is a large Arabic alarm disc with a sculpted blued-steel pointer on the rim indicating the time. In addition there is a large blued-steel hand which can be turned to set the alarm time. When the alarm is not used, it can be lined up with the hour pointer giving the illusion of a large hour hand.
The elaborately pierced and engraved silver case has a back cover containing a bell for the alarm and a hinged lid with a convex glass set in an engraved bezel. The engraving on the back depicts various flowers with a rose in the middle. Opening the glazed lid and pressing a catch allows the movement to be turned outwards. The watch can be wound through two winding holes in the back cover.
