The watches in the De Ville Trésor collection are especially thin and made of high-quality materials. The 40-mm edition has a 10.6 mm thick case made of 18-karat yellow, white, or Sedna gold. Sedna gold is Omega's in-house red gold alloy composed of gold, copper, and palladium. Classic black or brown leather straps with polished gold clasps keep these timepieces on your wrist. Along with most of the cases, the indices and hands are made of gold. The domed, silver dials feature a date display at 6 o'clock.

There are also limited editions featuring glossy, enamel dials in white, blue, or ivory, as well as exclusive models with diamond-set indices and bezels and mother-of-pearl dials.

If you're looking for a simple version of the De Ville Trésor, you should take a closer look at the three-hand gold models with a date display at 6 o'clock. The white gold variant with a blue dial is listed at 19,100 USD and limited to a run of 88 pieces. Finding a watch with a silver-colored dial is much easier. This model demands around 10,300 USD in mint condition and 8,800 USD pre-owned. Editions in yellow or Sedna gold cost a few thousand more.

The collection also includes 36-mm quartz watches in stainless steel with diamonds on the case. Thanks to their modest size, these models are an option for both men and women. That being said, their shiny and curvy looks are rather feminine, making them better suited for women. A mint-condition timepiece with a blue leather strap and dial costs almost 3,500 USD.

The modern Trésor models pay homage to Omega watches from the late 1940s, which were powered by the legendary 30-mm caliber. This large manual movement, which has been powering watches since 1939, masterfully fulfilled all requirements set forth in the Swiss observatory tests and ran incredibly precisely. Omega is one of the few manufacturers who has always participated in these tests.

The manual caliber 8511 also runs as precisely as a chronometer and powers current Trésor models. The Swiss manufacturer uses their in-house Co-Axial escapement in this movement, an alternative to the commonly used Swiss anchor escapement. The Co-Axial escapement is known for its high level of precision due to its improved energy efficiency and reduced friction. This results in a double barrel movement with a 60-hour power reserve.

It also has a freely oscillating silicon balance spring, which makes it resistant to magnetic fields up to 15,000 Gauss. Thanks to the sapphire glass case back, you can watch these manual movements in motion and admire the red gold balance bridge with Geneva stripes. Omega engraves the words "Anti-magnetic" and "> 15'000 Gauss" on the case back as well.
