Day, date, month and the moon, from the oldest name in watches.

A complete calendar shows the day, the date, the month and the moon, and needs correcting five times a year at the end of the short months. A perpetual calendar corrects itself and costs several times more. The complete calendar is the sensible one, and Blancpain has built the Villeret version around it since the 1980s.

Blancpain’s answer to the ugly corrector buttons most calendar watches carry is to hide them under the lugs, where a fingertip finds them. The serpentine blued hand points at the date on the outer track; the moon at six is the one that makes people ask what it is.

The 6654 comes in steel and in gold; this is the red gold case with the blue sunburst dial and a blue alligator strap, which is the combination Blancpain added to the line in 2021. At 40mm it is a full-sized dress watch, and 100 metres of water resistance is unusual for one.

Every figure here comes from the Amazon spec table and Blancpain’s published specification for the reference, not from handling the watch.

This unit is listed new by an independent dealer through Amazon, with Amazon’s 30-day return window on top of the dealer’s warranty; read the warranty line on the listing, because Blancpain’s own warranty runs from an authorised sale.

Gold Blancpain dress watches resell below their retail price on the secondary market, which is why dealer stock sits on Amazon under boutique retail. Buy it for the calendar and the case. Nothing here is investment advice.
