OMEGA first introduced the Seamaster 300 in 1957 – it was a watch designed especially for divers and professionals who worked underwater. More than half a century later, the timepiece makes a comeback in a completely upgraded and enhanced form, ready for a new generation of adventurers. This Seamaster 300 has a sand-blasted blue dial with 18K Sedna™ gold hands coated with “vintage” Super-LumiNova. The 18K Sedna™ gold bezel has a Ceragold™ ring and diving scale. The 41 mm grade 5 titanium case is presented on a grade 5 titanium and 18K Sedna™ gold bracelet. A transparent caseback makes it possible to see the anti-magnetic OMEGA Master Co-Axial calibre 8400 within.
