Seamaster Diver 300M Co-Axial 41 GMT Stainless Steel / Blue / Bracelet / SBS

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. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 25,200 vph the seconds hand advances 7 times a second.

2539.80.00 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue dial with a stainless steel case. It was a limited edition. Beyond the time it carries a gmt.

Self-winding chronometer, Co-Axial Escapement movement with rhodium-plated finish.
