Case and Dial Design

The watch case is constructed in three parts and fashioned from 18K yellow gold. It features a polished finish, with specific decorative elements including a serrated edge on the fixed bezel and a rounded case band. The lugs are described as curved and sloped with a '250 ans' commemorative design. The case back is transparent, allowing for visibility of the movement, and is secured by six screws, also featuring a serrated edge similar to the bezel. The light silvered dial is finished with an engine-turned guilloché pattern consistent with the '250 ans' commemorative theme. It is fitted with applied yellow gold baton markers, with yellow gold numerals at the 6 and 12 positions. The time is displayed via 'éventail' hands. The dial includes subsidiary displays for the day and date, as well as a sector for the power reserve indicator. An applied Seal of Geneva quality mark is present on the dial surface.

Movement and Mechanics

The watch is powered by the Vacheron Constantin Caliber 2475, a self-winding movement. The caliber is rhodium-plated and decorated with 'fausses côtes' patterns. It features 27 jewels and a straight-line lever escapement. The balance system is free-sprung and monometallic, oscillating at a frequency of 4 Hz, or 28,800 vibrations per hour. The movement is equipped with a shock absorber and a self-compensating flat balance spring. The movement includes a guilloché gold rotor. It is stamped with the Seal of Geneva Quality Mark, indicating compliance with specified production standards. The caliber provides indications for the day, date, and a 44-hour power reserve. External correctors are positioned to allow for the adjustment of the day and date displays.

Commemorative Context and Documentation

This timepiece was produced as part of a limited edition to celebrate the 250th anniversary of Vacheron Constantin in 2005. The edition comprised a total of 1755 watches distributed across different precious metal variants. There were 250 examples in platinum, 500 in 18K white gold, 500 in 18K pink gold, and 500 in 18K yellow gold, with five additional examples reserved by the company. The specific watch catalogued is marked as number 136 of the yellow gold series. The auction description reports that the object comes with its original fitted box and an accompanying certificate. All three main components—the dial, the case, and the movement—are signed by the manufacturer.
