Speedmaster Date 39 Stainless Steel / Black

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 sapphire crystal will resist everything short of deliberate abuse. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

The movement winds itself from the motion of your wrist. 46 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.

3813.50.01 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. Beyond the time it carries a chronograph.

Omega's execution of the ETA/Valjoux 7750, fitted to the Speedmaster Date through the 1990s and 2000s. It differs from the Speedmaster Reduced's calibre 1140 in construction rather than specification: the 1140 stacks a Dubois-Dépraz chronograph module onto a time-only base, while the 1152 is an integrated chronograph whose timing works belong to the movement's own architecture. That is what gives it a twelve-hour counter.

16 other watches in the library run the Omega 1152.
