OMEGA’s sporty Seamaster collection is a tribute to the brand’s maritime legacy. This exquisite example of our renowned watchmaking pays homage to OMEGA’s dive watch heritage and our adventurous pioneering spirit.
This model features a blue dial decorated with a wave pattern and a date window at the 3 o’clock position. The distinctive dial is visible through a scratch-resistant sapphire crystal. The blue unidirectional rotating bezel is mounted on a 41 mm stainless steel case with a helium-escape valve at 10 o'clock.
The watch is presented on a stainless steel bracelet. This OMEGA Seamaster Diver 300M is powered by the Co-Axial calibre 2500.
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
The day of the month, displayed in a window on a watch dial typically at the 3 o'clock or 6 o'clock position.
Helium escape valve
Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Unidirectional rotating bezel
A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.
