Blancpain Villeret Rose Gold — Flyback Chronograph Pulsometer | Ref. 6680F 3631 MMB

The flyback chronograph stands among the most demanding complications a watchmaker can attempt: where a conventional chronograph requires three sequential operations to reset and restart, the flyback performs all three simultaneously at a single press — a technical tour de force that once served navigators and surgeons, and today distinguishes the most ambitious dress chronographs in existence. Blancpain has mastered this complication within the Villeret's refined architectural vocabulary.

Automatic Calibre F385 powers this 18-carat rose gold example, delivering 50 hours of power reserve and an integrated flyback mechanism that transitions from one elapsed-time measurement to the next with a single stroke of the pusher. A pulsometer scale on the dial ring — calibrated for physicians to measure heart rate — adds a further layer of historical provenance, invoking the medical-instrument heritage of the classic chronographe de médecin.

With 23 mm between the horns and 3 bar water resistance, Ref. 6680F 3631 MMB wears with the patrician assurance its rose gold case warrants. Presented on a Mille Mailles bracelet, it represents the apex of the Villeret chronograph offering: a complicated, historically resonant piece from the world's oldest watchmaker, priced at €42,600 and positioned firmly among the most collectible flyback dress chronographs available today.
