Quick answer
Imitation Blancpain 6654-1127-55B watches are common on resale sites and social marketplaces, and most of them fail in the same handful of places: the moonphase disc, the calendar aperture alignment, the case profile, and the movement visible through the display back. The reference itself is the Villeret Quantième Complet in stainless steel, a complete calendar with moonphase that retails for five figures in US dollars. Treat every private listing as suspect until a watchmaker opens the case.

What reference 6654-1127-55B actually is
Blancpain builds this watch in a 40 mm stainless steel case with an opaline dial, applied gold hour markers, and a complete calendar showing day, date, month, and moonphase. The in-house calibre 6654 drives it, and the sapphire case back shows the movement bridges, rotor, and finishing. Retail sits in the five-figure USD range, which is why copies circulate. The price gap between a genuine example and a counterfeit is wide enough to attract fraud.

Prerequisites
- A 10x jeweler's loupe or a phone macro lens
- Daylight or a bright neutral lamp
- The reference's published specifications from the manufacturer
- A watchmaker willing to open the case back
How to evaluate a claimed 6654-1127-55B step by step
- Measure the case across the 4 and 10 o'clock lugs. Genuine examples sit at 40 mm, while many imitations run 41 to 42 mm because they use generic cases.
- Examine the moonphase aperture with the loupe. The genuine moon disc carries a smooth gradient finish and cleanly stamped stars.
- Check the calendar apertures. Day, date, and month windows should sit on the same horizontal line with even gaps between them.
- Run the crown through its positions. The genuine calibre sets the date, then the day and month, then the moonphase, with a firm detente at each stop.
- Turn the watch over and study the movement. A counterfeit usually shows a decorated rotor over a generic base calibre, or a solid case back where the real one is sapphire.
- Read the dial printing at an angle. Genuine lacquer sits flat against the opaline surface, and copies show raised or uneven lettering.
- Ask for service records and the original warranty card, then verify the serial with an authorized dealer or the brand directly.
- Have a qualified watchmaker open the case and confirm the calibre number before any money changes hands.
Legal risk and ownership problems
Counterfeit watches infringe registered trademarks, and US Customs and Border Protection seizes them at the border on a routine basis. Buying one is not a neutral act. You get no manufacturer service, no parts, and no warranty. Resale is effectively impossible through any legitimate channel, and repair shops often refuse to work on counterfeits because parts do not exist.

Legitimate ways to get the same look
A complete calendar with moonphase is available from several makers at lower prices. Longines, Baume & Mercier, Montblanc, and Frederique Constant all offer full calendar or moonphase models in steel, and each one can be serviced and resold. If the goal is a steel dress watch with a moonphase, these get you there without the legal and practical problems.

Bottom line
There is no shortcut to a genuine 6654-1127-55B. If a listing is priced far below market, the movement will not match the reference number. Verify with a watchmaker, buy from an authorized dealer or a documented private sale, and walk away from anything you cannot inspect.
