Description

To celebrate its role as the Official Timekeeper of the Olympic Games Tokyo 2020, OMEGA has produced this special commemorative timepiece.

The 42.00 mm case is in stainless steel and is mounted with a blue ceramic bezel ring filled with a white enamel diving scale. There is also a polished white ceramic dial with laser-engraved waves, along with blued indexes and hands, and the famous Seamaster name highlighted in red.

The NAIAD Lock caseback reveals a Tokyo 2020 Olympic Games emblem decorated on the sapphire crystal caseback. Behind the glass, you’ll find the OMEGA Co-Axial Master Chronometer Calibre 8800.

Each model in the collection is presented on a stainless steel bracelet and delivered inside its own Olympic Games presentation box, as an additional tribute to the event it so elegantly celebrates.

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

Behind the elegance of every Master Chronometer timepiece is the highest level of testing: 8 tests over 10 days, to ensure superior precision and anti‑magnetic resistance. We’ve raised our standards. You can too.
