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.

Characterised by its thin and elegant case, the Trésor line was first launched by OMEGA in 1949 and housed the legendary 30mm calibre. More than half a century later, it continues to impress with one of today’s most advanced mechanical movements.

This model has a polished 40 mm 18K Sedna™ gold case, which is presented on a blue leather strap. The domed blue dial includes a Power Reserve display at 12H, a Small Seconds display at 6H, along with hands and domed indexes in 18K Sedna™ gold.

Inside, this De Ville Trésor is powered by the OMEGA Co-Axial Master Chronometer Calibre 8935 and is certified at the industry’s highest standard of precision, chronometric performance and magnetic resistance.

Key materials

Sedna^TM Gold
Sapphire Crystal

1 / 2

Sedna^TM Gold

OMEGA has been using the exclusive 18K Sedna^TM Gold, its own fiery rose gold alloy, since 2012. Named after Sedna, an orbiting planetoid that has been described as one of the reddest in the solar system, Sedna^TM Gold not only bears all the standard characteristics of other 18K golds, but it also offers high resistance to the fading of colour and lustre over time. Its unique composition includes copper and palladium for colour and stability.
2 / 2

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.

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 and certified twice. First, the 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). Then, the watch head and its movement undergo eight Master Chronometer tests set by the Swiss Federal Institute of Metrology (METAS) with criteria of 0/+5 seconds per day.

Anti-Magnetic

Proprietary anti-magnetic materials

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.

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.

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.
5 / 6

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.
6 / 6

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 8935

Manual-winding movement with Co-Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. Power Reserve display at 12H and Small Seconds display at 6H. Free-sprung balance with silicon balance spring, two barrels mounted in series. Special luxury finish with 18K Sedna™ gold balance bridge with Geneva waves in arabesque.
