Speedmaster Reduced Stainless Steel / Black / Strap / AC Milan

In Context

At 39 mm it sits just under the modern norm — the band that suits the widest spread of wrists. The case back is closed, so the movement stays out of sight, and the plexiglass crystal scratches easily but polishes back out at home, which sapphire does not. 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. 42 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

3810.51.41 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case. It was a limited edition. Beyond the time it carries a chronograph.

The Omega 1143 is an automatic chronograph movement based on the ETA 2892. It features a chronograph module by Dubois-Depraz.

9 other watches in the library run the Omega 1143.
