Seamaster Diver 300M 42 mm

Since 1993, the Seamaster Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s most advanced innovation and design.

This 42 mm model is crafted in grade 2 titanium and OMEGA’s exclusive 9K Bronze Gold. It includes a green oxalic anodized aluminium bezel ring with a diving scale in vintage Super-LumiNova.

Sandblasted green aluminium is used to create the dial, which features PVD 18K Bronze Gold hands and blackened indexes, all filled with vintage Super-LumiNova. The other markings, including the OMEGA logo, are transferred in light brown and red.

The watch is presented on a brushed mesh bracelet with clasp, and is driven by the OMEGA Co-Axial Master Chronometer Calibre 8806, which can be seen through the sapphire-crystal and wave-edged caseback.

Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
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.)
Master Chronometer Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent caseback: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
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.
