Quick answer
If you are looking at a "Villeret 5220" with a four figure asking price and a seller who will not open the caseback, treat it as a fake until proven otherwise. Blancpain's Villeret line is a low volume dress watch family, and the 5220 reference was never a mass market piece, so the number of genuine examples floating around is small. Most watches sold under that reference are generic slim dress cases with a printed dial, a stock Japanese or Chinese automatic inside, and caseback engraving that does not match Blancpain's own wording. Real ones come with papers, a serial that matches between case and movement, and a service history you can check.
Why 5220 fakes exist at all
The counterfeit trade follows attention, and Blancpain gets a fraction of the attention Rolex and Patek get. That cuts both ways. Copies of this reference are less common than Submariner copies, but the ones that exist tend to be sloppy, because there is little money in getting a low demand dress watch exactly right. Sellers also lean on the fact that most buyers have never handled a real Villeret, so they cannot judge the case profile from photos alone.
Case and crystal checks
- Thickness: the real piece is a slim dress watch. Fakes sit thicker because the movement inside is a stock automatic that needs more room.
- Lugs: watch how the lugs flow into the case band. Copies have a flat, stamped look and sharp edges at the lug tips.
- Crystal: sapphire on the real watch has a slight dome and no distortion ring at the edge. Cheap copies use flat mineral glass or thin sapphire that reflects differently under light.
- Crown: signed, and sitting flush with the case band rather than proud or oversized.
Dial and printing
Blancpain prints and applies markers with tight tolerance. On a real Villeret dial the script is thin and even, the minute track is crisp, and the markers sit level. Copies show thick script, fuzzy edges under a loupe, and markers that are off center. Check the signature and the "Villeret" line for weight and spacing. If the variant has a small seconds or date, look at placement: fake subdials are often a fraction off center, and the sweep on a fake small seconds hand can stutter when you watch it up close.
The movement and caseback
Ask for a photo of the movement through the display back. Blancpain's in-house calibers show Geneva stripes, polished bevels, and a signed rotor or bridge engraving. Copy movements show a plain rotor with a sticker or a light laser etch. Serial numbers should match between the caseback and the movement, and the reference number should be stamped in a clean font. A seller who refuses a movement photo is telling you everything you need to know.
Papers, boxes and price
Full set fakes are common. The box is easy to print. The warranty card is harder, but even that gets cloned. Price is the loudest tell: an authentic 5220 in steel or gold does not sell for a few hundred dollars. If the number sits far below the gray market range for that reference, you are not getting a bargain.
If you already bought one
Get it opened by a watchmaker who knows the brand. A movement photo and a caliper reading on case thickness will settle it. Then decide whether to chase a chargeback or a return. Do not send it to a service center expecting work, because they will not touch it.
