[product_description]OMEGA first introduced the Seamaster 300 in 1957 - designed especially for divers and professionals who worked underwater. More than 60 years later, the collection has been completely upgraded, and includes this special model created in OMEGA’s own bronze alloy.
The 41 mm case and bezel are crafted from 9K Bronze Gold, while the brown ceramic bezel ring includes a diving scale in vintage Super-LumiNova. On the bronze dial, you’ll find recessed hour markers and open numerals with Super-LumiNova, as well as PVD Bronze Gold coloured hands.
Presented on a brown leather strap with a 9K Bronze Gold buckle, this timepiece includes a transparent sapphire crystal caseback, enabling a clear view of the OMEGA Co-Axial Master Chronometer Calibre 8912.

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).

Master Chronometer: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).

Time zone function: Allows the hour hand to be easily adjusted to different time zones without stopping the watch.

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.

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