Diver 300M Omega Co‑Axial Master Chronometer 43.5 mm
Black ceramic on NATO strap
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 a 5-stripe black and grey NATO strap with a brushed buckle and titanium loop, and is driven by the OMEGA Master Chronometer Calibre 8806, which can be seen through the sapphire-crystal on the wave-edged caseback.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Helium escape valve Helium escape valve

Screw-in crown Screw-in crown
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent case back Transparent case backA transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
