Moonphase 7121 White Gold - Diamond / Blue

In Context

At 33 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. At 8.35 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. 44 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.

7121/200G-001 is one of 2 executions of the 7121/200G base reference. Underneath they are the same watch; what separates this one is a blue sunburst dial and a white gold, diamond case. Beyond the time it carries a moon phase.

Classic Patek Philippe hand-wound movement with small seconds. Gyromax balance. Hallmarked with the Patek Philippe seal.
