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, with its scratch-resistant sapphire crystal, features a blue, wave-patterned dial with a date window at the 3 o’clock position. In addition to its central hour, minute and seconds hands, there is a GMT hand that completes one rotation around the dial every 24 hours. 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 2628.
24 hours GMT 24 hours GMTA GMT function means that the watch has a second hour hand which completes one full rotation in 24 hours and a 24-hour index on the dial. Particularly useful for wearers who wish to track two time zones.

Screw-in crown Screw-in crown
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
