Seamaster Diver 300M Automatic 41 Yellow Gold / Skeleton / Bracelet / 50th Anniversary

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. 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. 300 m is a professional diving rating, far past any demand a wrist is likely to make of it.

The movement winds itself from the motion of your wrist. 44 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.

2931.80.00 stands on its own in this catalogue — no other reference here shares its base number. It pairs a skeleton dial with a yellow gold case. It was a limited edition. Introduced in 1998.

Skeletonized version of caliber 1120; no date window. Yellow gold version.

1 other watch in the library runs the Omega 2401.
