A fake Blancpain 6654B timepiece is a copy of the Villeret Quantième Complet, a 40 mm watch with a complete calendar, a moon phase, and an in-house automatic caliber. The "6654B" tag is not a model name on its own. The B is the last character of the full reference, as in 6654-1127-55B, and it marks the strap and buckle set. On a copy, the weak points are the moon phase, the hidden calendar correctors, the dial text, and the movement finish.
What is the Blancpain 6654 reference, in plain terms?
The Villeret Quantième Complet 6654 shows the day, date, month, and moon phase with no extra buttons on the case side. Blancpain hides four correctors under the lugs, so the flanks stay smooth. A full reference stacks a case code, a dial code, and a strap code, which is why the same watch appears under several number strings.
Case and size
40 mm across, about 11 mm thick, with a stepped bezel and a sapphire caseback. Steel and red gold are the two common versions. Weight tells you a lot: a gold case feels dense in the hand, while a plated copy feels light and hollow.

The caliber 6654 movement
Caliber 6654 is an automatic with a 72-hour power reserve, a silicon balance spring, and about 321 parts. The rotor carries the brand name in raised relief, and the bridges show Geneva stripes with chamfered edges. Copies run on a generic automatic with a bolt-on calendar module, so the decoration is stamped or left bare.

Dial and moon phase
Applied Roman numerals, a sunburst or opaline base, and a moon-phase aperture set into a recess. The dial text sits in a tight serif with even spacing between letters. On a fake, the moon disc is a flat print and the text drifts or runs heavy.
How do you spot a fake Blancpain 6654B timepiece?
- Pushers on the case flank. The real 6654 has none. Recessed correctors sit under the lugs, so a copy with four side buttons exposes itself at once.
- Moon phase depth. A real disc sits in a machined recess with a sharp edge. Copies use a sticker or a flat print on the date wheel.
- Calendar alignment. Day, date, and month should sit on the same plane. Crooked windows point to a module dropped into a case that was not built for it.
- Dial text weight. Compare the spacing inside the brand name. Copies crowd the letters or use a heavier stroke.
- Rotor engraving. Deep, crisp relief on the real thing. Shallow sandblasting on most copies.
- Crystal. Flat sapphire with anti-reflective coating. Cheap copies ship with domed mineral glass that throws a blue or purple glare.
- Height. The genuine case sits low on the wrist. A stacked module adds height, which you feel under a shirt cuff.
- Date change. Watch the flip near midnight. A date that starts to crawl hours early points to a bargain module.
Why is the calendar the hardest part to copy?
A complete calendar drives four displays from one gear train and tracks a 29.5-day moon cycle. That takes extra parts, tight tolerances, and hand adjustment at the bench. Most copy makers skip the work and print the moon phase on a disc that turns with the date wheel.
You can test this in a minute. Set the watch to a known date, then use one corrector under the lug. A real 6654 moves one display per press. A copy often moves two at once or jams the date hand.
Replica tiers: what does each level get right?
The word "fake" covers a $30 quartz toy and a $900 copy with a decorated movement. Tiers shift by seller, but the split tends to look like this.
- Budget (about $20 to $60): quartz or a low-grade automatic, printed moon disc, wrong case size, side pushers.
- Mid (about $80 to $200): a Miyota or Seagull automatic with a calendar module, decent dial print, correct 40 mm case, mineral glass.
- Upper mid (about $250 to $500): sapphire glass, applied markers, a closer rotor, and dial text that holds up in photos. The calendar logic is still the weak link.
- Top copy (about $600 and up): a custom module, better polishing, and a rotor that mimics the real finish. Even here, corrector placement and moon disc depth give it away under a loupe.
Questions buyers ask
Can a fake 6654B run a true complete calendar?
Yes, some do, because sellers fit a third-party calendar module. The catch is the module, not the base movement. Check that all four displays advance in step and that the moon phase lands on the right day.
Does the "B" mean anything special?
No. It is the tail of the strap code in a full reference, and it appears across several Blancpain lines. A seller who calls "6654B" a distinct model is guessing.
Is a super clone hard to tell apart in person?
In a photo, sometimes. In hand, no. The giveaways are the corrector layout, the moon disc depth, the dial text weight, and the rotor finish.
What should I check first if I have 30 seconds?
Turn the watch over. If you see pushers on the case side, it is not a 6654. Then look at the moon phase for real depth and a sharp recess edge.
Before you buy or sell a 6654B
Ask for movement photos, a caseback shot with the reference engraved, and a short video of the date change. Papers and a service history carry more weight than the box. If the price sits far under the going rate for a steel 6654 on a strap, the watch is a copy or the seller is guessing about the reference.
