The 6654 in one paragraph
The Blancpain Villeret Quantième Complet 6654 is the dress watch most people picture when they hear the brand and are not thinking about a Fifty Fathoms. Steel case, 40mm across, day and month windows near 12, a serpentine date hand in blued steel, and a moonphase at 6. Inside sits the caliber 6654, an automatic built on the long-running 1150 base with a calendar module, about 72 hours of reserve and a 4Hz beat. The detail that trips up most replicas is the one buyers miss: the original has no seconds hand. Three central hands, and only two of them tell time. The third is the date pointer.
What I check before picking a build
- Hand count and shape. Any running seconds at the center, or a small seconds subdial, means the dial layout is wrong before you even look at the calendar.
- Date hand geometry. The genuine hand is thin, curved at the tip, and blued. Cheap versions use a flat stamped hand with a painted end that reads red under indoor light.
- Day and month apertures. Same size, level with each other, discs that sit flush and print clean at the edges. Misaligned windows are the fastest giveaway at arm's length.
- Moonphase behavior. The disc should advance in daily steps across a 29.5 day cycle. If it spins with the hour hand or never moves at all, the module is decorative.
- Corrector placement. Original 6654 watches hide recessed correctors under the lugs instead of putting pushers on the case band. Look for that before anything else.
- Case height. Past roughly 12mm the watch stops sitting under a shirt cuff the way a Villeret should.
First pick: the clone-calendar build
If I am spending real money on a replica 6654, this is the one I buy. The calendar is a purpose-built module rather than an add-on plate, so the day, month, date and moonphase all function and set from the correctors. The serpentine date hand tracks properly across the ring instead of drifting between markers, the apertures line up, and the case sits close to the original 40mm by 11.8mm footprint. You pay more, and stock moves slowly because fewer shops carry it, but it is the only tier where the watch reads correctly from across a table. Fit a dark alligator strap and it disappears into a suit.

Option two: Miyota base with a calendar plate
This is the value pick and the one most people should actually start with. A Miyota 9015 underneath drives a Chinese-made calendar module. Timekeeping is solid, service is easy, and the dial furniture is often 90 percent of the way to the top build. What you give up: the module can feel stiff when you push a corrector, the moonphase disc is sometimes printed flat rather than domed, and case thickness creeps up a few tenths of a millimeter. From a foot away nobody knows. In your hand, you do.

Option three: the budget steel version
Under about the price of a decent pair of shoes, you get the silhouette and nothing else. The calendar usually works in name only, the printing on the discs looks washed out, and the date hand is often the wrong color entirely. It is fine if you want the look for a single event. It is a poor choice if you plan to wear it weekly, because the calendar will stop tracking and the plating on the hands will not age well.
Bottom line
Rank the three by how often you will wear the watch, not by photos. The clone-calendar build wins for daily rotation, the Miyota version wins on money, and the budget tier wins only for occasional use. Check the hand count first, then the correctors, then the moonphase. Those three questions settle the 6654 faster than any spec sheet.
