[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 timepiece has been completely upgraded with an enhanced form that is ready for a new generation of adventurers.
This 41 mm stainless steel model includes a blue dial and a blue oxalic anodized aluminium bezel with its diving scale filled with vintage Super-LumiNova. The recessed hour markers and open numerals feature Super-LumiNova, which is also present on the rhodium-plated hands.
Presented on an ergonomic stainless steel bracelet, this timepiece includes a transparent sapphire crystal caseback, enabling a clear view of the OMEGA Co-Axial Master Chronometer Calibre 8912.

• Power reserve: 60 hours
• 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.
