A fake Villeret 6654 fails on four checks: the calendar correctors hidden under the lugs, the moonphase disc, the date hand, and the finishing on caliber 6654. The genuine Blancpain Villeret Complete Calendar ref. 6654 is a 40 mm automatic watch with an in-house movement, about 72 hours of power reserve, and setting pushers tucked beneath the lugs. Most replica and "first copy" versions move the correctors to the side of the case, print the moonphase, and leave the movement unfinished.

What is the Blancpain Villeret 6654?

The 6654 is Blancpain's complete calendar, a watch that tracks the day, date, month, and moon phase on one dial. It comes in a 40 mm case roughly 11.7 mm thick, in steel, rose gold, or white gold, with a sapphire case back.

The layout is distinctive. Day and month sit in twin apertures below 12 o'clock, the moonphase sits at 6 o'clock, and a serpentine date hand with a red tip sweeps the outer track. Blancpain pairs this with caliber 6654, an automatic movement with a 72-hour power reserve.

How do you spot a fake Villeret 6654?

Work through the case, the dial, and then the movement. Fakes get caught fastest at the case back, because the correctors and the movement are the hardest parts to copy.

1. Check for under-lug correctors

Blancpain hides the day, date, month, and moonphase correctors under the lugs so the case flanks stay smooth. Look at the case back near each lug: you should find small recessed pushers that a tool can press.

A fake usually shows four visible buttons on the case side, or no correctors at all. This one detail eliminates most counterfeit 6654s.

2. Inspect the moonphase disc

Genuine discs show a deep blue sky, sharp gold stars, and a finely detailed moon face. On fakes the stars look printed, the blue is flat, and the moon reads as a blurry sticker.

3. Test the date hand

The date pointer is serpentine, thin, and blued, with a red tip that lines up with the printed track. Replica hands are thicker, painted rather than heat-blued, and often stop short of the numerals.

4. Read the dial printing

Blancpain prints thin, crisp serif letters with even spacing. Fakes show fuzzy edges, wrong letterforms, heavy "Swiss Made" text, and day and month apertures that do not align with each other.

How do you check the movement on a 6654?

Turn the watch over. Caliber 6654 should show Geneva stripes, circular graining, polished screws, and an engraved rotor marked with the Blancpain name and the caliber number.

• Rotor engraving: depth, font, and alignment should be sharp, not stamped and shallow.
• Reference and serial engraving between the lugs should match the paperwork.
• Gold models should carry proper hallmarks on the case back and buckle.
• A solid steel back on a watch sold as a 6654 is a strong warning sign.

Why do fake 6654s get the details wrong?

Correctors under the lugs require a redesigned case, and a true moonphase adds parts and cost. Cheap copies reuse a standard calendar module and a printed disc instead.

That is why the tell is structural rather than cosmetic. Even a well-photographed listing tends to expose the shortcut once you ask for a case back photo.

What should a genuine 6654 cost?

Pre-owned steel ref. 6654 typically trades in the high four figures to mid five figures in US dollars, depending on box, papers, and condition. Gold versions run higher. A price far below market, especially from a private seller, is the first warning sign.

Fake Villeret 6654 FAQ

Is a "first copy" Villeret 6654 the same as a fake?

Yes. "First copy" and "AAA replica" are marketing terms for counterfeit watches. They copy the look but not the movement, so Blancpain will not service them and they hold no resale value.

Can a fake 6654 pass a visual check?

At arm's length, some can. On a bench, with the case back open and the correctors tested, they do not.

Does the 6654 have a display case back?

Yes. The modern Villeret Complete Calendar 6654 uses a sapphire case back, so the movement is visible to the owner and to any inspector.

What is the fastest single check?

Ask for a photo of the case back with the lugs in frame. Under-lug correctors are the hardest feature to fake at low cost.
