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.

The case of this 43.5 mm model is crafted from black ceramic and grade 5 titanium and includes a black ceramic bezel with a white enamel diving scale. The dial is also brushed black ceramic [ZrO2] and features laser-engraving to create raised waves.

The skeleton hands and raised indexes in PVD titanium are filled with white Super-LumiNova, while the helium escape valve has been given a conical design.

The watch is presented on an integrated black rubber strap with a polished-brushed black ceramic [ZrO2] buckle, and is driven by the OMEGA Master Chronometer Calibre 8806, which can be seen through the sapphire-crystal on the wave-edged caseback.

Calibre Omega 8806: Self-winding movement with a 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. Special luxury finish with rhodium-plated rotor and bridges with Geneva waves in arabesque.

FEATURES

Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).

Automatic watch: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).

Ceramic watch: A casebody created from a single block of pressed ceramic, which is first heated in an oven and then three-dimensionally machined. OMEGA’s ceramic watch cases are extremely scratch-resistant and shock-resistant.

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.

Titanium: A highly stable, lighweight and hard metal used for cases and bracelets. OMEGA titanium watches are made of grade 2 and grade 5 titanium. Grade 5 offers a brighter grey color than grade 2 and can be polished more easily.

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.
