The real Omega De Ville Trésor is defined by a short list of numbers you should memorize before you look at any watch: a 40 mm case, roughly 10.5 mm of thickness, 20 mm between the lugs, 30 m of water resistance, and an automatic co-axial calibre with 60 to 72 hours of power reserve. Those figures are the baseline. The Trésor is a slim dress watch, so a case that reads thick in profile, a lug gap that measures wide, or dial text placed in the wrong order will stand out once you know the genuine proportions.

What to look for on a genuine Trésor
Case and crystal
The Trésor keeps a narrow, polished bezel and thin, gently curved lugs. The domed sapphire crystal rises past the bezel line and sits almost flush with the case edge. Check the side profile first, since that is where a mismatch in thickness shows. Most references carry a sapphire display back, so the movement is meant to be visible.
Dial and hands
Expect applied indices, thin faceted hands, and a clean hierarchy of print: the Omega symbol and name under 12, the De Ville line below it, and the certification wording on Master Chronometer examples. Finish varies by reference, including opaline silver, sun brushed surfaces, and enamel style lacquer. There is no luminous paint on the dress references, so glow plots on the dial are a mismatch.
Movement and caseback
The Trésor runs a co-axial automatic with twin barrels in series, a silicon balance spring, and a 3.5 Hz rate. Master Chronometer versions are METAS certified and rated to 15,000 gauss. On the back you should see the exhibition crystal, the certification engraving, and a rotor finish that matches the reference material.

Parameter bands to compare
- Case diameter: 36 mm to 40 mm, with most current references at 40 mm
- Case thickness: 10.0 mm to 11.0 mm, and anything well above 11 mm is off profile
- Lug width: 19 mm to 20 mm, most at 20 mm
- Water resistance: 30 m or 3 bar, a dress watch rating
- Case materials: steel, Sedna gold, yellow gold, Canopus gold, titanium
- Movement: automatic co-axial, 25,200 vph, 60 to 72 hours of reserve
- Accuracy: 0 to +5 seconds per day for Master Chronometer, -4 to +6 for COSC certified movements
Common pitfalls
- Judging from front photos only. Thickness, lug curve, and crystal dome only show in a side shot.
- Assuming every Trésor shares one dial layout. Date at 3, small seconds at 6, and no date all exist.
- Mixing up the De Ville Trésor with the De Ville Prestige, which has different proportions and dial furniture.
- Ignoring the strap taper and the signed buckle, which are part of the reference identity.
- Accepting a spec sheet that contradicts the caseback engraving or the certification text on the dial.
FAQ
Is the Trésor a quartz watch?
No. The line is mechanical and automatic, with a co-axial escapement.
Does every Trésor have a date window?
No. Some references place a date at 3 o'clock, some use a small seconds sub dial at 6, and some carry no date at all.
What does Trésor mean?
Trésor is French for treasure, and Omega uses the name for its thinnest De Ville dress models.
How thin should the case be?
Around 10.5 mm is the working figure. Measure at the crown and at the case middle, since both should agree.
