Short answer: the replica De Ville 424.10.40 longtail is a counterfeit of the Omega De Ville Prestige in stainless steel, and "longtail" is not an Omega word. It is marketplace shorthand for a reference almost nobody clones in volume. That single fact changes how you should read a listing. With a mass-produced Submariner copy you can find a hundred threads comparing batches. With a low-demand dress reference you get a handful of makers, thin documentation, and a lot of guesswork dressed up as precision.

What the 424.10.40 reference actually is

The 424 prefix belongs to the De Ville Prestige line: a thin steel dress watch, roughly 39.5 mm across, with slim lugs, applied baton markers, a date at three, and a co-axial movement under a solid or display back depending on the exact suffix. It is a quiet watch. It sits under a cuff. There is no bezel drama to distract the eye, which is exactly why a bad copy of it fails so fast.

Treat every spec sheet in a listing as unverified. Omega publishes case dimensions, movement, and reference data on its own site, and that is the only version worth comparing against. Sellers routinely copy the genuine numbers into their descriptions and then ship something that matches none of them.

"Longtail" is jargon, not a model name

You will see the term bolted onto titles on marketplace and forum listings. It comes from the long tail of catalog references: the hundreds of genuine models that sell in small numbers. A longtail replica is one built for that thin end of the market. Expect fewer factories, fewer revisions, and less shared knowledge about which batch is good.

The practical result is uneven quality. Two sellers can both say "longtail De Ville" and mean completely different watches, one with a properly finished caseback and one with a laser-etched sketch of a hippocampus.

Where the money actually shows

  • Case profile. The Prestige is thin and the lugs curve. A copy that sits tall on the wrist or has flat, slabby lugs is the first giveaway at arm's length.
  • Dial printing. Fine print under the 12 is where cheap dials smear. Look for crisp, evenly weighted text, not gray mush.
  • Applied markers. They should sit level and catch light the same way across the dial. Crooked markers are common on low-volume builds.
  • Hands. Dauphine hands need a clean center crease. Polished blades that look painted are a bad sign.
  • Date window. Framing should be sharp, and the disc should sit flush. A sunken or uneven window reads instantly.
  • Caseback engraving. Depth and consistency matter more than the logo itself. Shallow, dotty engraving means the tooling was cheap.

Movement and the numbers to check

Most copies in this family run a Miyota or Seagull automatic, and a few claim a cloned co-axial. Claims are cheap. Ask for a movement photo with the caseback off, a timegrapher reading, and the measured case diameter with calipers. Real sellers have those. A seller who only sends stock images does not.

Also ask about water resistance honestly. A dress watch copy is not a diver, and gasket quality on niche builds is a coin flip. I would not trust one near a sink regardless of what the listing says.

Price bands and what they buy

Below about $150 you are buying a fashion watch with a logo. The case finish will be soft, the bracelet or strap will be an afterthought, and the movement will be unregulated. Around $250 to $450 you reach the range where a maker has actually spent time on the dial and case profile. Above that, you are paying for a name and a story, not a better watch, unless the seller can document the build.

The parts nobody mentions

There is no warranty and no service network. When an automatic movement in a counterfeit dies, you find an independent watchmaker willing to touch it, or you throw it away. Resale is close to zero. In the US, importing counterfeit goods is prohibited and Customs can seize and destroy a shipment, so the money is gone with nothing to show. That risk sits with the buyer, not the seller.

A checklist before you commit

  1. Confirm the reference in the listing matches the watch in the photos, not a stock image.
  2. Ask for caliper measurements of the case diameter and thickness.
  3. Request a timegrapher photo showing rate and amplitude.
  4. Look at a close crop of the dial printing and the date window.
  5. Ask which movement is inside, by name and version.
  6. Check whether the seller has any history of shipping to your country.

The De Ville is a hard watch to fake well because there is nothing to hide behind. If a seller cannot answer basic questions about a thin steel dress watch, the watch is not the problem. The listing is.
