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 rhodium-plated hands coated with "vintage" Super-LumiNova. The polished ceramic bezel ring has a Liquidmetal™ diving scale.The 41 mm brushed and polished grade 5 titanium case is presented on a matching bracelet. A transparent caseback makes it possible to see the anti-magnetic OMEGA Master Co-Axial calibre 8400 within.
