Description

Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s best innovation and design.

This 44 mm chronograph model is crafted from stainless steel and 18K Sedna™ gold, and includes a polished black ceramic bezel with a Ceragold™ diving scale. The pushers are also polished black ceramic, as well as the dial which features laser-engraved waves and a date window at 6 o’clock.

The subdial hands are 18K Sedna™ gold, along with all other hands and indexes which are filled with white Super-LumiNova.

The watch is presented on a stainless steel and 18K Sedna™ gold bracelet and is driven by the OMEGA Master Chronometer Calibre 9900, which can be seen through the sapphire-crystal on the wave-edged caseback.

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.

Stainless Steel

Stainless steel is certainly the most conventional of watchmaking materials for outer craftsmanship, and offers beauty, strength and affordability. OMEGA uses 316L stainless steel. Known for its corrosion-resistance and high lustre after polishing, this material is often the ideal choice for watches in both daily-use and high-stress situations such as diving and adventure.

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.

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.
