Master Ultra Thin Réserve de Marche Pink Gold / Eggshell / Alligator

In Context

At 39 mm it sits just under the modern norm — the band that suits the widest spread of wrists. At 9.9 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. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

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.

Q1372510 stands on its own in this catalogue — no other reference here shares its base number. It pairs a ivory matte dial with a pink gold case.

Self-winding movement with small seconds, date, and power reserve display. We will update with the difference between this and the 938 as soon as more info presents itself.
