Sorry, but this watch is no longer available.
Find another watchCharacterised by its thin and classic gold case, the Trésor line was first launched by OMEGA in 1949 and housed the legendary 30mm calibre. More than half a century later, the De Ville Trésor has been reintroduced, equipped with one of the most advanced mechanical movements the brand has ever unveiled.
This model has a silvery opaline dial with a domed vintage "clous de Paris" structure and a date window at 6 o'clock. The 40 mm 18K Sedna™ gold case is presented on a brown leather strap with an 18K Sedna™ gold buckle. This De Ville Trésor is powered by the anti-magnetic OMEGA Master Co-Axial calibre 8511 - a unique manual winding movement.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
This measures the space where a strap or bracelet would be placed.
This is the full length of the case, from the top lugs to the bottom lugs.
This is the full width of the watch’s case, excluding the crown and pushers.
When viewed from the side, this measures from the base of the watch to the surface of the glass.

OMEGA has been using the exclusive 18K SednaTM 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, SednaTM 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.

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.

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.

A key component of this timepiece is the Co-Axial escapement, which is able to maintain accuracy over a longer period of time. What’s more, all parts affecting accuracy are produced with non-ferromagnetic materials, ensuring the watch is protected from the strong magnetic fields produced by everyday items.
Our Master Co-Axial Chronometer movements benefit from the Co-Axial escapement, which is able to maintain accuracy over a longer period of time. All parts affecting accuracy are also produced with non-ferromagnetic materials, ensuring that that precision will not be affected by magnetism (up to 15'000 gauss). 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).
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.
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.
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.
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.
