Description

Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. OMEGA’s 21st century models stay true to the original’s dive watch design, while introducing exciting new materials and movements.

This 43.50 mm model, cased in black ceramic [ZrO2] and Sedna™ gold, has a black ceramic dial with laser-ablated waves in positive relief. The polished Sedna™ gold indexes and facetted hands, filled with white Super-LumiNova, contrast beautifully with the black dial. Completing the look is an integrated black rubber strap with black ceramic buckle.

The polished-brushed oriented caseback with wave-edged design features OMEGA’s patented NAIAD LOCK. Powering the watch is OMEGA’s Co-Axial Master Chronometer Calibre 8806.

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.
