De Ville Trésor Master Chronometer Yellow Gold / White 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 10.82 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight, 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. 72 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 25,200 vph the seconds hand advances 7 times a second.

435.53.40.21.09.001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a white dial with a yellow gold case.

Handwound version of Omega's in-house 'Master Chronometer' movement. Manual-winding movement with Co-Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. Free-sprung balance with silicon balance spring, two barrels mounted in series. Time zone function. Special luxury finish with 18K Sedna™ gold balance bridge with Geneva waves in arabesque.
