Short answer
Reference 6654-3642-55B is a Blancpain Villeret Quantième Complet in stainless steel. A copy is a watch built to look like it. Copies of this reference come from Chinese workshops. They copy the dial, the case shape, and the calendar layout. None of them use the Blancpain caliber 6654. In the US, selling or buying one is a trademark violation, and Customs can seize the package.

Calendar correctors sit under the lugs. US retail is in the low five figures. Blancpain updates prices, so check the maker's current listing.

What the copy market sells
Copies split into price tiers. Low tier runs about 70 to 150 US dollars. Mid tier runs about 200 to 400. The top tier, sold as "super clone" or "1:1," runs about 500 to 800. Those numbers come from seller listings. Prices move.
Movement is the main gap. Most copies use a generic Chinese automatic. Some add a calendar module. Owner reports note that the moon phase on cheaper copies is a 24-hour disc, not a 29.5-day cycle. Day and month windows often ignore month length, so the owner resets them by hand. Movement finish does not match the caliber 6654.
Checks that separate a copy from the real watch
- Correctors. The genuine watch has recessed correctors under the lugs. Many copies put pushers on the case side.
- Movement. Look through the sapphire back. Blancpain finishes the bridges and engraves the rotor. Copies show plain decoration and wrong text.
- Moon phase. The genuine disc advances one step per day on a 29.5-day cycle. Copies often run a 24-hour disc.
- Case shape. Lug profile, bezel step, and crown shape differ by fractions of a millimeter.
- Engravings. Reference number, serial, font, and depth.
Legal position in the US
Counterfeit watches are illegal goods. Title 18, Section 2320 of the US Code covers trafficking in counterfeit goods and carries prison time. The Lanham Act gives trademark owners a civil claim. Customs and Border Protection seizes counterfeit watches. Watches and jewelry rank near the top of seized categories by manufacturer's suggested retail price. A seized package is destroyed. The buyer gets nothing and has no refund route.
What buyers cannot get
No warranty. No parts catalog. No service from Blancpain. No resale value that holds. Sellers change domains and handles, so a second order from the same source is not assured. Order counts, factory names, and production totals for copies are not published, so any figure you see is a seller claim.
If the goal is a complete calendar
Other makers sell complete calendars in steel. Pre-owned prices sit well under the Blancpain number. No legitimate new watch with a true complete calendar and moon phase sells at copy prices.
