Master Ultra Thin Moon White Gold / Grey / 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. 45 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.

1363540 stands on its own in this catalogue — no other reference here shares its base number. It pairs a grey sunburst dial with a white gold case. Introduced in 2017.

Mechanical automatic winding movement, 246 parts, 28,800 vibrations per hour, 38-hour power-reserve. Indications for hour, minute, central seconds, date, moon phases.
