Description

It was with OMEGA’s maritime legacy in mind that the brand launched its Planet Ocean line in 2005. The stylish OMEGA Seamaster Planet Ocean 600M Master Chronometer GMT pays homage to OMEGA’s dive watch heritage.

This model, with its scratch-resistant sapphire crystal, features a black ceramic dial with Arabic numerals, a date window at the 3 o’clock position and a central GMT hand. Mounted on the 43.5 mm stainless steel case is the world's first polished bi-ceramic black and white bezel. Here, the numerals and scaling are delivered in contrasting colours to separate night from day.

Other features include an alveol screw-in caseback and a stainless steel bracelet with patented extendable foldover clasp.

The OMEGA Seamaster Planet Ocean 600M Master Chronometer GMT is water resistant to 60 bar (600 metres / 2000 feet), and has a helium-escape valve. The OMEGA Master Chronometer calibre 8906 at the heart of this timepiece can be seen through the transparent caseback. To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology).

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.

The advantages
of this watch

Inside this timepiece are the revolutionary components that guarantee the highest standards of performance. From the Co-Axial escapement for long-lasting precision, to the silicon balance spring for superior anti-magnetism, OMEGA has conquered every challenge that matters.
