A replica De Ville 424.10.37 copies an Omega De Ville Prestige. 424.10.37 is a reference stem, not a full reference number. Omega adds three more groups, for example 424.10.37.20.02.001, and each group sets a part: dial color, hands, bracelet or strap. Listings that use the short form mix several watches under one label.
Factory specs behind the number
Omega lists the 424.10.37 variants in the De Ville Prestige line. The common case is steel, 39.5 mm across, with a fixed bezel and a sapphire crystal. Water resistance is 30 m. Movement in the period covered by these references is the Co-Axial calibre 2500, an automatic with a 48 hour power reserve. Caseback type and dial finish change with the suffix, so the full number comes first in any comparison.
How replicas of this reference are sold
Most copies come from Chinese factories and ship with labels such as 1:1 or Swiss made. The labels describe marketing tiers, not a standard. A copy at $150 to $300 carries an Asian automatic or a quartz. Copies above $400 often claim a Swiss or cloned Co-Axial movement. Ask for photos of the actual watch, not catalog renders.
Checks before you buy
- Full reference number on the listing and on the caseback photo.
- Case diameter measured with calipers: 39.5 mm, not 40 mm or 41 mm.
- Dial print: De Ville and Co-Axial spacing, font weight, and alignment at 6 o'clock.
- Caseback engraving depth and the seam between the caseback and the case.
- Seconds hand sweep: 8 beats per second at 28,800 vph, fewer on a cheap quartz.
What the numbers do not tell you
Weight, lug width, and caseback style differ by suffix and by factory batch. Omega publishes no single spec sheet for the short form 424.10.37. Compare against photos of the exact full reference, and treat any claim of same factory, same specs as unverified.
