Patrimony Moon Phase and Retrograde Date Pink Gold / Silver

In Context

At 42.5 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 9.7 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. At 28,800 vph the seconds hand advances 8 times a second.

4010U/000R-B329 is one of 2 executions of the 4010U/000R base reference. Underneath they are the same watch; what separates this one is a silver dial and a pink gold case. Introduced in 2016. Beyond the time it carries a moon phase.

The 275-part Manufacture Vacheron Constantin Caliber 2460 R31L with its 40-hour power reserve drives the hours and minutes hands, the precision moon-phase display as well as the retrograde date. With this unprecedented movement, the Maison has succeeded in offering an easily adjustable mechanism. Its crown offers simple and smooth access to all three functions of the timepiece. In its first position, it serves to wind the watch. Once pulled out to the second notch, it can be turned clockwise to set the date or counter-clockwise to adjust the moon phase, while the third and last position controls time-setting. A transparent sapphire crystal reveals the 2460 R31L movement and its 22K gold oscillating weight, adorned with Vacheron Constantin’s signature Maltese cross motif. The hand-crafted finishing of the caliber reflects absolute mastery of the watchmaking art and traditional skills.
