Traditionnelle Moon Phase and Power Reserve Pink Gold / 270th Anniversary

In Context

At 36 mm it is classically proportioned: the size a dress watch was understood to be for most of the twentieth century, and small enough to sit under a cuff. At 8.9 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 is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 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.

83570/000R-H060 is one of 2 executions of the 83570/000R base reference. Underneath they are the same watch; what separates this one is a white guilloche dial and a pink gold case. It was a limited edition. Beyond the time it carries a moon phase.
