VACHERON CONSTANTIN. AN ATTRACTIVE PLATINUM AUTOMATIC PERPETUAL CALENDAR CHRONOGRAPH WRISTWATCH WITH MOON PHASES AND LEAP YEAR INDICATION

In 1992, Vacheron Constantin introduced 'Les Complications' collection, a line dedicated to the showcase of its horological expertise beyond time-only watches. This exclusive series featured technical masterpieces such as tourbillons, minute repeaters, and perpetual calendars with chronograph functions. According to the Maison's archives, fewer than 300 examples were created over a ten-year span until the series concluded in 2002.

The present timepiece stands out for its rare platinum case and refined proportions, boasting a symmetrical dial layout that offers four registers arranged in a cross: day and 12-hour counter, date and 30-minute register, month with leap year indicator and a moon phase indicator with running seconds. The white dial marked with 'sigma' signs at 6 o'clock indicates the use of white gold hour markers.
