Speedmaster Super Racing Master Co-Axial Stainless Steel / Black / Bracelet

In Context

At 44.25 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 14.92 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. 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.

329.30.44.51.01.003 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black matte dial with a ceramic, stainless steel case. Introduced in 2023. Beyond the time it carries a chronograph.

Spirate™ System for fine rate adjustment, 2 barrels mounted in series, time zone function. Central hour, minute and chronograph seconds hands, small seconds hand, 12-hour and 60-minute recorders.
