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 pays homage to OMEGA’s dive watch heritage.

This model, with its scratch-resistant sapphire crystal, features a black dial with a date window at the 3 o’clock position. The orange unidirectional rotating divers’ bezel is mounted on a 42 mm stainless steel case on a stainless steel bracelet.

The OMEGA Seamaster Planet Ocean 600M is water resistant to 600 metres / 2000 feet / 60 bar, and has a helium-escape valve. The OMEGA Co-Axial calibre 8500 at the heart of this certified chronometer timepiece can be seen through the transparent caseback.

Key materials

Stainless Steel
Aluminium
Sapphire Crystal

1 / 3

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.
2 / 3

Aluminium

Aluminium has the advantage of being a truly lightweight material used for decorative components. Through anodisation, it offers an extensive range of colours for the creation of eye-catching watch parts such as bezel rings, applied elements on the dial, and hands. In particular, OMEGA’s special anodisation process has achieved aluminium bezel rings that are nearly double as hard as regular versions, therefore making them more resistant to outer damage.
3 / 3

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

At the heart of this timepiece is the Co-Axial escapement, a revolution in watchmaking when first introduced. The reduced stress on the moving parts means less need for lubrication, longer-lasting accuracy and a more stable power reserve rate. In short, this timepiece performs better for longer.

1 / 5

Superior Precision

Our Co-Axial movements benefit from the revolutionary Co-Axial escapement within their design. With less friction created, they are able to maintain accuracy over a longer period of time, as well as a more stable power reserve rate. Each movement is Chronometer-certified according to international standard ISO3159, requiring a precision of -4/+6 second per day, following the tests at the Official Swiss Chronometer Control (COSC).
2 / 5

Water-Resistance

To ensure the integrity of our timepieces at depth, not just some but all watches are fully immersed in water and pressure is applied up to the point of the guaranteed water resistance. By submerging each watch in water we have chosen – yet again - to exceed normal testing standards.
3 / 5

5-Year Warranty

In our quest to raise industry standards and push the boundaries of quality, all OMEGA watches are offered with a full 5-year warranty. This customer promise shows the confidence we have in the excellence of our timepieces, and provides extra trust and assurance when choosing your watch.
4 / 5

Less servicing

Expect fewer visits to the service centre. The Co-Axial escapement is designed to reduce friction inside the movement. As a result, less lubrication is needed and hence less servicing. Compared to non-Co-Axial watches, the intervals between getting your watch serviced will be much longer.
5 / 5

Shock-resistance

During the homologation process, OMEGA watches are tested to the extreme. This phase includes shock examinations, to confirm reliability and to check that its precision is maintained after a severe impact. All OMEGA timepieces are designed to withstand shocks corresponding to a 1-metre drop on a hard wooden floor. For a standard 150g timepiece, this sudden and rapid acceleration is an equivalent force of up to 5,000 G on the watch head.

Movement Calibre OMEGA 8500
