Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s best innovation and design.
This 42 mm model is crafted from stainless steel and includes a blue ceramic bezel with a white enamel diving scale. The dial is sun-brushed PVD chrome colour ceramic and features laser-engraved waves and a date window at 6 o’clock.
The skeleton hands and raised indexes are blued and are filled with white Super-LumiNova, while the helium escape valve has been given a conical design.
The watch is presented on a blue rubber strap and is driven by the OMEGA Master Chronometer Calibre 8800, which can be seen through the sapphire-crystal on the wave-edged caseback.
Calibre Omega 8800: Self-winding movement with Co-Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. Free sprung-balance with silicon balance spring, automatic winding in both directions. Rhodium plated finish with Geneva waves in arabesque.
Anti-Magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Automatic Watch: A self-winding watch or automatic watch uses a mechanical movement whose main spring is wound automatically by the natural motion of the wearer's arm.
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 Case Back: A transparent case back - 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.
Domed scratch-resistant sapphire crystal with anti-reflective treatment on both sides
