Patrimony Perpetual Calendar Pink Gold / Anthracite

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 8.96 mm thick it is about average for a modern wristwatch. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

The movement winds itself from the motion of your wrist. 40 hours of reserve carries it overnight, but not through a weekend in a drawer.

43175/000R-B343 is one of 3 executions of the 43175/000R base reference. Underneath they are the same watch; what separates this one is a grey dial and a pink gold case. Introduced in 2017. Beyond the time it carries a perpetual calendar.

This hand-wound movement bearing the Hallmark of Geneva is equipped with an oscillating weight featuring the particularly meticulous finishing that is the signature of fine watchmaking. Beating at a frequency of 2.75 Hz (19,800 vibrations per hour), it has an approximately 40-hour power reserve. Calibre 1120 QP drives indications of the hours, minutes and perpetual calendar featuring the day of the week in a subdial at 9 o’clock, the date in a subdial at 3 o’clock, the month and leap year on a 48-month subdial at 12 o’clock, and the moon phase at 6 o’clock.

3 other watches in the library run the Vacheron Constantin 1120 QP.
