The complete calendar, in white gold, with the serpent hand.

Quantième complet is French for complete calendar: day, date, month and moon phase on one dial, adjusted by hand at the end of short months. It is the calendar layout of 1940s dress watches, and Blancpain has kept it in the Villeret line since the brand was revived in the 1980s. The pointer date, a hand that sweeps a numbered track around the edge of the dial, is the part that makes it read as old; on this one the hand ends in a serpent’s head, a Blancpain signature.

The 6654 generation moved the correctors under the lugs, so the case sides stay clean and you set the calendar with a fingertip rather than a pin, and put a silicon balance spring in the movement, which shrugs off magnets. Seventy-two hours of reserve means it keeps the calendar over a weekend off the wrist.

The title says white gold and Quantième Complet, and the photograph shows the taupe sunray dial and black alligator strap. The Amazon rows say the dial is white and skeleton; neither is true, they are template values, and the photograph is the reliable part. The full reference is not stated; Blancpain’s white gold Quantième Complet with this dial is in the 6654 series.

Whether the watch is new with Blancpain’s warranty or a dealer-serviced piece is not stated in the rows we read; ask, and ask for the box and papers. Every figure here comes from the listing and from Blancpain’s published description of the 6654, not from handling the watch.

This is a regular Amazon listing from an independent dealer, Luxor Watches on the day we read it, with Amazon’s 30-day return window; it is not a Luxury Stores pre-owned unit. The second button opens the live search for Villeret complete calendars in case this one has sold.

Gold Blancpain dress watches have resold for well under new and close to what pre-owned buyers paid, sometimes more, sometimes less; that is a pattern, not a promise, and nothing here is investment advice.
