Short answer
A fake Villeret Eight Days copy stands or falls on four points: the case profile, a hand-wound movement with a true long reserve, the dial printing around the power reserve scale, and the finish of the caseback. If any one of those four fails a physical check, the watch is a low-tier build no matter how clean the listing photos look.
What you are comparing against
The Villeret Eight Days is a hand-wound dress watch built around a long power reserve and a matching indicator on the dial. Case sizes across the references sit in the 40 to 42 mm band, and the case stays thin relative to its diameter. That simple layout is what makes copies easy to grade: small errors in thickness, dial spacing, or crown action show up right away. Before you compare anything, pull the factory spec sheet for the exact reference and keep it open next to the seller photos.
Checks before you buy
- Write down the reference number the seller claims and match it against the catalog photos for that version.
- Request caliper photos of case diameter, thickness, and lug width, not a tape measure held against a wrist.
- Confirm the movement is hand-wound. A rotor visible through the caseback on an Eight Days model is an instant fail.
- Study the power reserve scale. Markers should sit at even spacing and line up with the hand at both ends of the arc.
- View the dial text at 10x magnification. Copy printing frays at the serifs, while a good dial holds a hard edge.
- Inspect the caseback engraving. Etched text looks grey and shallow, stamped text shows a defined shoulder and depth.
- Check the crown grip and stem length, since a short stem makes winding feel loose through the first few turns.
Testing the eight-day reserve
- Wind the watch until the crown stops and count the turns it takes.
- Set the time against a reference clock and rest the watch crown-up on a desk.
- Record the rate at the 24, 96, and 192 hour marks with a timing app or a timegrapher.
- Compare the drift you measure with the tolerance the seller quoted before purchase.
A copy that keeps time for three days and dies on day four is not an eight-day watch. That test costs you a week, which is cheaper than a return argument.

Red flags
- No caliper photo and no caseback photo in the listing.
- The same stock render used across every listing the seller posts.
- Thickness quoted as a single number with no tolerance range.
- Refusal to share a power reserve test result from a batch they already sold.
Questions worth asking
- Which batch is this, and when was it assembled?
- Does the crown wind smooth through the full reserve or grind near the stop?
- What rate deviation did the last unit of this batch show over a week?
Bottom line
Measure the case, confirm the movement winds by hand, read the dial under magnification, and run the reserve test yourself. Those four checks separate a serious Villeret Eight Days copy from a display piece that only looks right in photos.
