The replica Blancpain 6654B copies the Villeret Quantième Complet: a 40mm stainless steel dress watch with a complete calendar, day and month windows below 12 o'clock, a moon phase at 6 o'clock, and a serpentine date hand that sweeps the outer track. A strong replica runs an automatic movement with a real calendar module, holds a case close to the original profile, and prints the dial with clean, raised text. A weak one hides a stamped moon disc, a date hand that misses the numerals, and a case that sits too tall. The checklist below covers what to measure, what to press, and what to walk away from.
What the 6654B label tells you
6654 is the number Blancpain uses for its Villeret complete calendar family, and the trailing letter on a listing marks a case and strap combination more than a new watch. Replica sellers reuse the code as a model name, so treat 6654B as a description of the look, not a guarantee of specs. Ask the seller for exact case diameter, thickness, movement caliber, and strap width before you compare photos.
Prerequisites
- Reference photos of the genuine dial, caseback, and movement
- A jeweler's loupe or a macro lens for your phone
- A timegrapher or a timing app for rate and beat error
- A calendar pusher tool or a wooden toothpick
- A written return window from the seller
How to inspect the watch, step by step
- Measure the case across the bezel without the crown. Expect 40mm. Anything past 41mm breaks the dress watch proportions.
- Measure thickness through the center of the caseback. The genuine watch sits low on the wrist, so a copy above 13mm looks bulky under a cuff.
- Check the lug shape and strap width. Straight lugs with a brushed top and polished flank match the original look. Thick, rounded lugs read as cast parts.
- Study the dial printing with magnification. Roman numerals, the brand name, and the Swiss Made line at 6 should be crisp, level, and slightly raised. Flat or blurry ink is the first sign of a budget build.
- Inspect the day and month windows below 12. The apertures should be square, evenly spaced, and centered over aligned discs.
- Test the serpentine date hand. It should travel the outer track and land centered on each numeral after the date jumps.
- Examine the moon phase at 6 o'clock. A good disc shows a defined moon with surface detail and stars on a dark blue ground. A flat white circle with no depth is a stamped part.
- Set the calendar with the correct pushers, one function at a time. Day, date, and month should jump cleanly and stop in the middle of the window.
- Advance the moon phase with its own pusher. The disc should step in small, even increments and never slip backward.
- Flip the watch and inspect the movement through the sapphire back. Look for a signed rotor, Geneva stripes, blued screws, and clean beveled edges. Laser-flat or misaligned engraving is a warning.
- Run a rate check with the watch fully wound. A healthy copy holds near plus or minus 10 seconds a day with steady amplitude and no knocking sound.
- Work the crown. Winding should feel smooth, the crown should pull to two positions without wobble, and the hands should set without jumping.
- Skip a water test unless the seller states a real resistance rating. A dress case in this family is not dive rated, and a replica gasket is not a promise.
- Check the strap and buckle. The grain should be even, the stitching straight, and the pin or deployant should close with a firm click.
Common flaws to reject
- Case over 13mm thick with an oversized domed caseback
- Painted moon phase or a printed date track instead of applied elements
- Day and month discs that stick between windows
- A date hand that overshoots or undershoots the numerals
- Sapphire with heavy edge distortion or a purple tint
- A movement that stalls the moment the calendar module engages
Price and expectations
Replica pricing tracks the movement. Entry copies with a basic automatic and a simple calendar plate sell low, mid-tier builds with a modified 2824 and a proper module sit in the middle, and top builds with a clone layout and hand-finished bridges cost the most. Spend on the case profile, the dial, and the calendar mechanism, because those are the parts you see and use every day. A clear return window matters more than any spec sheet.
Care after purchase
Wind the watch at the same time each day, set the calendar with the pushers rather than the crown, and avoid date changes between 9 p.m. and 3 a.m. while the mechanism is engaged. Have the movement serviced every three to five years and keep the watch away from strong magnets and hot water. Store it dial up with the crown to the side if it runs fast on the wrist.
