A day hand that flies back to Monday.

A retrograde hand does not go round. It moves along an arc, one step a day here, and when it reaches the end a spring throws it back to the start. Doing that without jarring the rest of the movement, and making the jump land exactly on Monday every week, is the kind of small mechanical problem Blancpain likes. On the 6668 the arc sits at nine, the days are printed on a white fan, and the hand is blued steel so you can find it.

The big date at six is the other complication: two discs so both digits sit in one window, readable across a desk. Around them the dial is plain Villeret, applied Roman numerals on white, leaf hands, and the double-stepped bezel on a 40mm steel case. The 6950 inside has a silicon balance spring and a three-day reserve, so the day and date do not need resetting after a weekend off the wrist.

The listing is a title and a model number: Villeret Grand Date Retrograde Day 40mm, 6668 1127 55B. There are no spec rows and no description, so there is nothing to contradict, and the photograph matches the reference: steel, white dial, big date at six, day fan at nine, black strap. The calibre, reserve and water resistance here are Blancpain’s published figures, not the seller’s.

The seller is MS-TR JAPAN, a marketplace seller shipping from Japan with delivery quoted at two to four weeks, and there is no condition statement, no service history and nothing about box or papers. Ask all three before buying, and use the 30-day return window to have the watch checked when it arrives. Every figure here comes from the listing and from Blancpain’s published description, not from handling the watch.

This is a regular Amazon listing from a marketplace seller with Amazon’s 30-day return window; it is not a Luxury Stores unit and the seller has not published a condition. The second button opens the live search for Villeret Grande Dates in case this one has sold.

Blancpain Villerets 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.
