Object description

Case and Dial Design

The wristwatch features a solid 18K pink gold case designed with a two-body construction and polished finish. A notable aesthetic element is the presence of teardrop-shaped lugs that attach the strap to the circular case body.

The two-tone silver dial is configured with a satiné silver outer ring, which displays the days of the month using red-painted Arabic numerals. Faceted triangular indexes, also in pink gold, provide the hour markers, complemented by Arabic numerals at the quarters. The dial integrates multiple indications, including apertures for the day, month, and moon phases, as well as a subsidiary seconds register. Pink gold dauphine hands are used for the time, while a central red arrow hand tracks the date.

Movement and Mechanics

Powering the piece is the Jaeger-LeCoultre Calibre 494/A, a gilt brass movement featuring 18 jewels. The mechanical architecture incorporates a straight-line lever escapement and a cut bimetallic compensation balance designed to maintain timing precision.

The movement decoration includes fausses côtes, a traditional decorative motif applied to the plates and bridges. Technical features intended to support consistent operation include a shock absorber system and a self-compensating Breguet balance spring. Both the dial and movement are signed by the manufacturer.
