Master Ultra Thin Tourbillon White Gold / Blue Enamel

In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11.3 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.

13234E1 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue guilloche dial with a white gold case. Introduced in 2019. Beyond the time it carries a tourbillon.

Automatic movement with tourbillon escapement; 302 parts, height 7.1mm.
