Short answer
"Replica de Ville 424.13.40" is search shorthand for a copy of the Omega De Ville Prestige Co-Axial, reference 424.13.40.20.02.001. The real watch is a 39.5 mm stainless steel dress watch with a silver dial, a leather strap, and the Omega calibre 2500. Replica versions sell for $60 to $450. They run quartz or third-party automatic movements. None carry the calibre 2500. Most come from factories in Guangzhou, China.
What the reference number means
Omega builds references from blocks. The first block, 424, is the De Ville Prestige line. The second block, 13, is the case metal, stainless steel. The rest of the blocks cover case size, movement, dial color, and strap. Omega does not publish a full decoding key. Confirm the last five digits against a dealer listing before you treat them as fixed.

What the copies are
Movement
Copies in the $60 to $150 band use quartz. The seconds hand ticks once per second. Automatic copies in the $200 to $450 band use a Chinese copy of the ETA 2824 or a Miyota 8215. No copy has a co-axial escapement. Some carry a decorative plate stamped "2500" and "Co-Axial." That plate is a print job, not a mechanism.
Case and finish
Steel cases run 39 to 40 mm. Thickness runs 1 to 2 mm over the original in most samples because the third-party movement sits taller. Better grades brush the case sides and polish the bezel. Gold-tone versions use plating a few microns thick. That plating wears through at the crown and lugs.
Dial and hands
Dial printing is the first tell. Look at the wordmark and the "SWISS MADE" line at 6 o'clock. Copies show thick strokes and uneven spacing. Hands run thick, and the seconds hand length is off.
Price bands
- $60 to $120: quartz, mineral glass, plated case, printed caseback
- $150 to $250: automatic, sapphire front crystal, 316L steel case
- $300 to $450: automatic, sapphire front and back, cleaner dial print, leather strap
These are listing prices. Quality varies inside each band.
Checks before you buy
- Ask for the base movement. "Co-Axial" is not an answer.
- Ask for a photo of the caseback.
- Ask for a 10x macro of the dial text.
- Check the crown. Genuine crowns are signed. Copies show no logo or a misaligned one.
- Weigh the watch. A steel 39.5 mm De Ville on leather runs near 60 g. Many copies sit under 50 g.
Legal note
A watch carrying the Omega name or logo without authorization is a trademark counterfeit. U.S. Customs and Border Protection can seize shipments at the border. Personal-use purchases carry lower risk than bulk import, but the item is still subject to seizure. Omega is a brand of the Swatch Group.
Bottom line
The 424.13.40 copy reproduces a dress watch shape. Nothing inside it matches the calibre 2500, the co-axial escapement, or the original finishing. Buyers who want the movement should shop the used market instead.
