Vacheron Constantin - Patrimony Perpetual Calendar Ultra-Thin Blue Dial

Vacheron Constantin – Patrimony Perpetual Calendar Ultra-Thin Blue Dial

Vacheron Constantin launched another adaptation of one of its most symbolic models, the Patrimony Perpetual Calendar Ultra-Thin, portrayed by a sunburst silk completed blue dial outlined by a 41 mm pink gold case. 

Oneself winding manufacture 1120 QP type drives the signs of the hours, minutes, moon stage at 6 o’clock and perpetual calendar with day of the week in a counter at 9 o’clock, date in a counter at 3 o’clock, just as month and jump year on four year counters at 12 o’clock.

Unlike basic calendars that require manual adjustment after every period of under 31 days, the perpetual calendar assesses the jump year cycle, with its 31, 30 or 28-day months and the quadrennial return of February 29th. This implies that once effectively set, and assuming that the watch runs continuously, the calendar signs will require no further manual adjustment until the year 2100.

The moon stage show is embellished in champlevé lacquer whose tone is just uncovered after ultra-exact terminating at exceptionally high temperature (approx. 1000°C).

Beating at a pace of 2.75 Hz (19,800 vibrations each hour) and guaranteeing an autonomy of 40 hours, the Caliber 1120 QP measures a simple 4.05 mm thick, a genuine accomplishment of designing for a self-winding perpetual calendar development. Obvious through the straightforward sapphire gem caseback, the openwork Maltese cross-molded swaying weight comprises no under 276 components and is outstandingly wrapped up.

Coordinated to a dull blue of the crocodile calfskin lash equipped with a collapsing catch, the Vacheron Constantin Patrimony Perpetual Calendar Ultra-Thin Blue Dial (ref. 43175/000R-B519) has a cost of Euro 79,000 (Tax Included)/US$ 78,000 (Tax Excluded).

This new perpetual calendar watch is the fourth of another Patrimony arrangement with blue dials which includes hand-wound, self-winding and retrograde day-date models with costs beginning from Euro 18,800 (Tax Included)/US$ 18,600 (Tax Excluded). vacheron-constantin.com
