Object description

Case and Dial

The watch is housed in a 14K pink gold case measuring 59 mm in diameter. The exterior of the cover features a taille-douce engraving of the cypher "F G", while the caseback is polished. The watch is a hunter-style pocket watch with the crown and bow positioned at the 3 o'clock mark relative to the dial layout.

The dial is constructed of enamel and incorporates various decorative elements. It provides a digital calendar display (à guichets) showing the day, month, and date through apertures. A moon phase indicator is integrated into the subsidiary seconds register at the bottom of the dial. The auction description reports a hairline crack present on the dial surface.

Movement and Complications

The watch is powered by a 20''' gilded brass movement. It features a going barrel and a straight-line lever escapement. The balance assembly consists of a cut bimetallic compensated balance with gold poising screws and a blued steel hairspring with a terminal curve. Regulation is managed via a polished steel index-regulator.

The watch functions as both a minute-repeater and a chronograph. The repeating mechanism incorporates a silent centrifugal governor for regulation, while the chronograph mechanism is situated on the top plate. This combination of complications is managed within a substantial 20-ligne format.
