SIHH 2009: Vacheron Constantin Patrimony Traditionnelle Perpetual Calendar Chronograph

PRESS RELEASE: The Patrimony Traditionnelle Perpetual Calendar Chronograph Watch

The exterior of the Vacheron Constantin Patrimony Traditionnelle Perpetual Calendar Chronograph timepiece is as exceptional as the movement it houses. In keeping with the Patrimony Traditionnelle line, the 18K pink gold case is elegant, simple and classic. The generously-sized 43 mm case guarantees excellent legibility of all the indications on the dial.

As well as snailed counters and a painted black minute-track, the silvered opaline dial presents a multi-toned finish in the spirit of Vacheron Constantin’s historic chronographs. The watch enthusiast will immediately pick out affiliations with the chronographs of the 1940’s.

The mechanical manual-winding 1141 QP movement makes 18,000 vibrations per hour and has a 48-hour power reserve. Besides the hours, minutes and small seconds at 9 o’clock, it features chronograph functions with a centre direct-drive seconds hand and a 30-minute counter at 3 o’clock. The perpetual calendar indicates the days of the week, months and leap years in windows, as well as the astronomical phases of the moon and a date hand at 6 o’clock.

The moon, sometimes happy, sometimes melancholy, is hand-engraved from a gold plate. Like all Vacheron Constantin movements, the 1141 QP calibre is distinguished by the meticulous chamfering work of the C?tes de Genève bridges and the circular-graining of the plate, both done by hand.

Water-resistant to a pressure of 3 Bar, the equivalent of 30 metres, the 18K pink gold case features a sapphire crystal back through which one can admire the remarkable complexity and exceptional architecture of the 1141 QP movement.
