Master Control Chronograph Calendar Stainless Steel / Silver / Novonappa

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 12.05 mm it is a tall case, and it will catch on a cuff. 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. 65 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

4138420 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver sunburst dial with a stainless steel case. Introduced in 2020. Beyond the time it carries a chronograph.

Self-winding movement combining a chronograph with a complete calendar and moon phase.
