What the replica De Ville 424.13.40 represents
The reference 424.13.40 points to an Omega De Ville Prestige with a 39.5 mm case. A replica version copies that shape, dial layout, and strap style while using a different movement. You will not get Omega's co-axial escapement or its warranty. The goal of this guide is to help you compare a replica against the real reference so you know what you are looking at.
Key specs to compare
- Case diameter: 39.5 mm
- Case material: stainless steel
- Movement: Omega Co-Axial Calibre 2500 (real), often a generic automatic or quartz in replicas
- Dial: domed, with Roman numerals or stick markers depending on the exact variant
- Date window: at 3 o'clock
- Crystal: domed sapphire with anti-reflective coating on the real watch
How to check a replica listing step by step
- Ask the seller for the exact reference number and compare it to Omega's official catalog.
- Request close-up photos of the dial, caseback, and clasp.
- Measure the case diameter with calipers if you have the watch in hand. Anything far from 39.5 mm is a sign of a lower-tier copy.
- Check the date window position and font. On the real 424.13.40 the date sits at 3 o'clock and uses a clean sans-serif numeral.
- Look at the crown. It should sit flush against the case and carry the Omega symbol.
- Inspect the caseback engraving. The real watch has deep, crisp text; replicas often have shallow or blurry marks.
- Listen to the movement. A smooth sweep with 25,200 vibrations per hour (7 beats per second) is typical for the Calibre 2500. A ticking quartz or a jerky 6 bps sweep suggests a cheaper replica.
Movement and case details
The genuine De Ville 424.13.40 runs on the Omega Co-Axial Calibre 2500, an automatic movement with a free-sprung balance and a power reserve around 48 hours. Replicas usually use a generic Chinese automatic, a Miyota, or a quartz module. The case on the real watch is 39.5 mm wide and about 10 mm thick, with lugs that curve down for a close fit. A replica often gets the thickness wrong, making the watch sit taller on the wrist.
Dial and hands
Dial variants for the 424.13.40 include silver, blue, and mother-of-pearl. Hands are leaf-shaped or dauphine depending on the version. On a replica, the printing on the dial can look fuzzy under a loupe, and the hands may be too thick or too thin. The applied Omega logo should be polished and raised. A flat printed logo is a common tell.
Strap and bracelet
Most 424.13.40 references come on a leather strap with a pin buckle or a deployant clasp. Replica straps often use bonded leather or synthetic material that cracks within weeks. Check the stitching density and the buckle engraving. The real buckle has crisp, even lettering.
Legal and practical notes
Buying or selling a replica watch can violate trademark laws in the United States and many other countries. Customs officers may seize counterfeit goods. If you want the look of the De Ville 424.13.40 without legal risk, consider a licensed homage brand or a pre-owned genuine Omega from a reputable dealer.
