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.
All OMEGA watches are delivered with a 5-year warranty that covers the repair of any material or manufacturing defects. Please refer to the operating instructions for specific information about the warranty conditions and restrictions.
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.

1 / 4
Grade 2 Titanium
Titanium alloys are light, corrosion-resistant, biochemically inert and able to withstand extreme temperatures. These properties make them particularly appropriate for products in the aircraft, spacecraft and medical sectors. They achieve the perfect balance between solidity, corrosion-resistance and workability. Grade 2 titanium offers a dim grey colour and suits mostly "brushed" finished pieces. It has featured in a number of OMEGA timepieces used for sport and space exploration, where light reflections should be avoided.

SednaTM Gold
OMEGA has been using the exclusive 18K SednaTM Gold, its own fiery rose gold alloy, since 2012. Named after Sedna, an orbiting planetoid that has been described as one of the reddest in the solar system, SednaTM Gold not only bears all the standard characteristics of other 18K golds, but it also offers high resistance to the fading of colour and lustre over time. Its unique composition includes copper and palladium for colour and stability.

Ceramic
OMEGA has unrivalled expertise in the use of ceramics, dating back more than 10 years. Taking its origin from the Greek word "keramos", ceramic is an inorganic, non-metallic substance obtained by firing at high temperatures. It allows the creation of completely dense watch parts with exceptional mechanical properties. Ceramic is one of the most popular choices for customers when selecting their timepiece, thanks to its appealing colour range and specific properties, such as it being two times lighter than stainless steel, hardwearing, highly scratch-resistant, chemically inert, hypoallergenic, environmentally friendly and non-magnetic.

Sapphire Crystal
To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.
