OMEGA is proud to include the Swiss Made mark on all of its watches. This simple wording guarantees a standard of quality established over many centuries and is a world-renowned symbol of excellence.
Celebrating OMEGA’s role as Official Timekeeper of the Olympic Winter Games, this exclusive Seamaster Diver 300M combines a sporty design with unique details in tribute to Milano Cortina 2026.
Delivered inside a special presentation box, the 43.5 mm watch is crafted in white ceramic and grade 5 titanium. This includes the white ceramic bezel ring, which reveals a laser-ablated diving scale in positive relief. To create a wintry look, the white ceramic dial includes laser-engraved frosting, with a finger trace pattern inspired by the “26” of the Milano Cortina 2026 emblem. Completing the dial design, the rhodium-plated hands and indexes have been filled with white Super-LumiNova, while the varnished central seconds hand has been given a subtle blue gradient.
The grade 5 titanium caseback features a stamped Milano Cortina 2026 emblem, forever associating this watch with the XXV Olympic Winter Games. Powered by the Co-Axial Master Chronometer Calibre 8806, the timepiece is worn on a white rubber strap, with its buckle in grade 5 titanium.
Anti-magnetic
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer
Label given to a watch which has been successfully tested by an accredited and independent laboratory in order to receive a certificate compliant with the chronometer ISO 3159 standard.
Helium escape valve
Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
Master Chronometer Certified
Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Unidirectional rotating bezel
A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.

Key materials
Grade 5 Titanium
Ceramic
Sapphire Crystal
1 / 3
Grade 5 Titanium
Titanium alloys are light, corrosion-resistant, biochemically inert and able to withstand extreme temperatures. These properties make them particularly appropriate for products in the aircraft, spacecraft and medical sectors. They achieve the perfect balance between solidity, corrosion-resistance and workability. Grade 5 titanium offers a bright grey colour that is close to that of stainless steel, and suits both "brushed" and "polished" finishing.
2 / 3
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, and non-magnetic.
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
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.
Master Chronometer Certified
Superior Precision
Twice as precise as any officially certified chronometer
Our Master Chronometer watches are tested twice. First, the movement is tested as a chronometer by an accredited and independent laboratory, in accordance with ISO 3159, requiring a precision of -4/+6 seconds per day to achieve chronometer certification. Then, the watch head and its movement undergo eight tests set by the Swiss Federal Institute of Metrology (METAS) with criteria of 0/+6 seconds per day to earn Master Chronometer certification.
Everyday items such as mobile phones, metal clasps on handbags, laptops, MRI, induction hobs or automatic doors; subject a watch to magnetic fields and can affect its performance. To prevent the risk of permanent deviations of up to several minutes a day we've conceived movements with antimagnetic materials, such as the silicon balance spring, capable of withstanding the highest fields.
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.
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.
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.
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.
