Master Chronograph Stainless Steel / Sector Dial

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 12.1 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, 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.

1538530 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 2017. Beyond the time it carries a chronograph.

Mechanical automatic winding movement, 277 parts, 28,800 vibrations per hour, 65-hour power-reserve. Functions: hour, minutes. Chronograph:, minute and seconds counters.
