Vacheron & Constantin 18ct Gold Triple Date Wristwatch

Partially verified

This Vacheron & Constantin wristwatch, dating to approximately 1952, features an 18ct gold case and an astronomic function. The watch includes triple date indications and moon phases. The case is described as massive and polished, incorporating teardrop-style lugs and measuring 36 mm in diameter. The dial, finished in a pink tone, is equipped with applied gold indexes and Arabic numerals. It includes an auxiliary seconds dial, an outer graduation for the days of the month, and apertures for the days of the week, months, and lunations. The timepiece is powered by a 12 1/2''' movement finished with rhodium plating and "fausses côtes" decoration. The mechanism comprises 17 jewels, a lever escapement, and a monometallic balance adjusted for temperatures, supported by an antishock system and a self-compensating flat balance-spring. All three main components—the dial, case, and movement—are signed by Vacheron & Constantin.
