Diver 300M Omega Co‑Axial Master Chronometer 42 mm
Titanium ‑ Tantalum ‑ Sedna™ Gold on Titanium ‑ Tantalum ‑ Sedna™ Gold
Since 1993, the Seamaster Diver 300M has enjoyed a legendary following.
This 42 mm model is a Limited Edition of 2,500 pieces and features a brushed case made from grade 2 titanium, with a crown, bezel ring and helium escape valve in 18K Sedna™ gold. In contrast, OMEGA has used tantalum to create the base of the bezel for a distinctive blue-grey tone.
The titanium dial features positive sun-brushed waves. The skeleton hands and raised indexes are 18K Sedna™ gold and are filled with white Super-LumiNova.
The watch is presented on a grade 2 titanium bracelet with tantalum and 18K Sedna™ gold links. An image of the OMEGA Seahorse can be found on the transparent caseback, through which you can see the OMEGA Master Chronometer Calibre 8806 inside.
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).
