Patrimony Moon Phase and Retrograde Date White 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/000G-H070 is one of 3 executions of the 4010U/000G base reference. Underneath they are the same watch; what separates this one is a silver dial and a white gold case. Introduced in 2016. Beyond the time it carries a moon phase.

Self-winding movement with Minutes, Hours, Retrograde hand-type date, Precision moon phase, Stop seconds device. Hallmark of Geneva certified.
