Description

OMEGA first introduced the Seamaster 300 in 1957 as a watch especially for divers. On this contemporary model, the legendary design has been transformed for luxury style.

The 41 mm case has been made from platinum-gold and features a green ceramic bezel with a platinum Liquidmetal™ diving scale. Most captivating of all is the watch’s deep green dial, which is made from the precious stone malachite. It includes 18K white gold hands that are filled with “vintage” Super-LumiNova.

Presented on a green leather strap, the watch is driven by the OMEGA Master Chronometer Calibre 8913, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).

Platinum

Platinum stands out in the luxury world for its rarity, enduring silvery whiteness and brilliant shine. It is also highly unreactive and has a remarkable resistance to corrosion. The rarity of the material is often associated with exclusivity and wealth, which is why OMEGA uses 950 platinum for exceptional models of prestige. These watches offer wearers a distinctive look and a unique feel unlike any other metal.

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.

LiquidmetalTM

Since 2010, OMEGA has bonded its ceramics with an alloy called LiquidmetalTM, which offers new decoration possibilities in a metal grey colour with superior scratch-resistance and enduring stability. Composed of titanium, zirconium and copper, this amorphous alloy is three times as hard as stainless steel. When bonded with ceramic parts, LiquidmetalTM can be offered in contrasting finishes (brushed or polished), thanks to the difference in hardness between the two materials.

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.
