Short answer

The Blancpain Villeret Quantième Complet 6654B is a stainless steel calendar watch with a 40 mm case, day and month windows at 12 o'clock, a moon phase at 6 o'clock, and a serpentine date hand. Fakes of reference 6654 are common because the moon phase dial sells well. Check the case back, the correctors, the dial print, and the movement before you pay. No single photo proves a watch is real.

What the 6654B reference covers

Blancpain places the Quantième Complet in the Villeret line. A reference such as 6654-1127-55B breaks into the calibre code 6654, a case code, and a strap code. The steel version measures 40 mm across. The calendar shows day, date, and month, plus a moon phase. Blancpain uses recessed correctors for the calendar settings, not pushers that stick out from the case band. Confirm corrector placement for the exact reference with a dealer or the official spec sheet.

Points to inspect

  • Case back: expect an engraved reference, a serial, and the Blancpain name. Fakes show thin fonts, uneven spacing, and shallow engraving.
  • Moon phase: the genuine aperture is cut clean and the moon disc carries a defined face. Fakes show a blurred disc and painted stars that sit off center in the aperture.
  • Serpentine date hand: the genuine hand is slender with one curve. Fakes use a thick hand with a blunt tip.
  • Dial print: Blancpain and Villeret lettering stays sharp at 10x magnification. Fakes show bleed and thicker strokes.
  • Case size: 40 mm. Fakes often measure 41 mm to 42 mm and use a flat lug profile.
  • Movement: a sapphire case back shows the rotor, bridges, and finishing. Fakes use a stock ETA or Seagull calendar module, or a printed moon disc driven by a 24 hour wheel.

Price and trade signals

Counterfeit 6654 listings sit in the low hundreds of US dollars. Pre-owned steel 6654 watches trade in the thousands. The two price bands do not overlap. A seller with no movement photos, no serial photo, and no service record is a risk. Counterfeit watches enter the US in express mail and small parcels, and US Customs and Border Protection publishes seizure data each year.

Verification steps

  1. Ask for a photo of the case back with the serial.
  2. Ask for a photo of the movement with the rotor turned.
  3. Compare case size, thickness, and lug width with the official Blancpain spec sheet.
  4. Have a watchmaker open the case and time the date and moon phase change.
