Quick answer
Reference 6654-1127-55B is a Blancpain Villeret Quantième Complet in stainless steel with a white dial and a black alligator strap. Copies of it exist in large numbers. Most fail on three things: the dial layout, the case-side correctors, and the movement. A counterfeit also carries legal risk in the United States. Selling one is trafficking in counterfeit goods under 18 U.S.C. 2320.

Where fakes break down
Dial
On the real dial the day and month apertures are cut into the dial plate, not printed. The serpentine date hand is heat-blued steel with a red tip. Copies use a stamped hand with a painted tip, and the date track sits at the wrong radius. Moon phase discs on fakes are printed decals. The genuine disc has a gold moon on a dark blue ground.
Case and correctors
The 6654 has recessed correctors for day, month, and moon phase. Date is set through the crown. Fakes often fit a single pusher, or fake the corrector holes with no mechanism behind them. Lug shape, bezel step, and caseback engraving differ on close inspection. The caseback carries the reference number and a serial. Copies usually carry a generic stamp or an incorrect serial pattern.
Movement
A 72-hour power reserve is easy to test. Wind the watch fully, set it down, and check it after three days. Most copies stop well before 72 hours. Genuine calibre 6654 finishing includes Geneva stripes, chamfered bridges, and a signed rotor. Copies show rough plating and no anglage.
Prices and paperwork
The genuine 6654-1127-55B sells in the five-figure USD range at retail. Copies sell for a few hundred dollars. A full set includes the Blancpain box, warranty card, and instruction booklet. Serial numbers on the card should match the caseback.
Legal note
US Customs and Border Protection seizes counterfeit watch shipments. Importing and reselling them exposes the seller to criminal charges and civil liability under the Lanham Act. A counterfeit is not a used Blancpain. It has no service history, no parts support from the brand, and no resale value.
