De Ville Trésor Master Chronometer Small Second Stainless Steel / Blue

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 10.05 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. 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.

435.13.40.21.03.002 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue dial with a stainless steel case. Introduced in 2021.

Hand-wound movement with small seconds at 6:00. Finished for use in stainless steel watches.
