Object description

Case and Ornamentation

The pendant watch is integrated into a larger ornamental piece, specifically a finely carved and pierced green jade panel. The overall aesthetic incorporates a two-body, solid, and polished construction that serves as the foundation for the watch assembly. A defining feature is the diamond-set ornamentation, which includes 27 round diamonds arranged to represent serpents on the bezel and the bow.

Functionally, the watch is a back-winder, with the case back secured by two screws. The entire unit is complemented by a matching 41 cm chain, which is also embellished with jade and diamonds to match the pendant's theme. The dimensions of the unit are 35 mm by 52 mm, fitting within the carved contours of the jade panel.
