Description

Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. This 44 mm chronograph is a Numbered Edition model and is built from grade 2 titanium, 18K Sedna™ gold and tantalum, which can be found on the base of the bezel and the middle links of the bracelet.

The 18K Sedna™ gold bezel ring features a laser-ablated diving scale, while the polished blue ceramic [ZrO2] dial is distinguished by laser-ablated waves, a date window at 6 o’clock, and subdial rings with touches of 18K Sedna™ gold.

The side of each case includes an 18K Sedna™ gold plate engraved with each unique Numbered Edition number. Turning the watch over reveals an OMEGA Seahorse, which has been laser-engraved and lacquered white on the sapphire crystal. Through the glass, you can see the OMEGA Co-Axial Master Chronometer Calibre 9900, certified by the Swiss Federal Institute of Metrology (METAS).

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.

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.

A new look for your watch

Your watch and strap should go together perfectly, but that doesn't mean you can't experiment with different combinations. Why not mix things up and see what happens? You may discover a look that's as individual as you are.

The advantages
of this watch

Behind the elegance of every Master Chronometer timepiece is the highest level of testing: 8 tests over 10 days, to ensure superior precision and anti‑magnetic resistance. We’ve raised our standards. You can too.
