Speedmaster 57 Master Chronometer 40.5 Stainless Steel / Blue / Bracelet

In Context

At 40.5 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 12.99 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 is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 60 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.

332.10.41.51.03.001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue sunburst dial with a stainless steel case. Introduced in 2022. Beyond the time it carries a chronograph.

Manual-winding chronograph with column wheel and Co-Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. Silicon balance-spring, 2 barrels mounted in series, time zone function. Central hour, minute and chronograph seconds hands, date function, small seconds counter, 12-hour and 60-minute counter. Rhodium plated finish with Geneva waves in arabesque.
