Blancpain Villeret 43.6mm Flyback Chronograph Pulsometer Rose Gold 6680F-3631-55B WHITE BROWN CROCODILE

The Blancpain Villeret 6680F-3631-55B distinguishes itself with its 43.6mm rose gold case housing a sophisticated flyback chronograph and a highly specialized pulsometer scale. The polished case features the Villeret collection’s signature double-stepped bezel, with elegantly curved chronograph pushers integrated into the caseband for a streamlined profile. It is presented on a brown crocodile leather strap with a rose gold deployant buckle. The white dial is a study in clarity, featuring applied rose gold Roman numerals and feuille hands, both filled with luminescent material. The central focus is the pulsation scale, calibrated for 30 pulsations, printed in red around the outer track, which allows a medical professional to directly measure heart rate using the chronograph seconds hand.

Driving the watch is the self-winding Caliber F385, a modern high-frequency movement operating at 36,000 vibrations per hour for precise chronograph measurements to 1/10th of a second. The flyback complication enables the timing sequence to be reset and immediately restarted with a single push of the lower chronograph pusher, a function developed for timing consecutive events. The column wheel and vertical clutch architecture ensure smooth engagement of the chronograph functions without stuttering of the seconds hand. Through the sapphire caseback, the movement’s impeccable finishing is visible, including perlage on the mainplate, polished chamfers on the bridges, and a gold-coated rotor.

This specific watch is in mint condition and is new, supplied with its open papers. Blancpain’s Villeret line is consistently sought after by collectors for its classical design language and technical substance, with complicated models like this flyback chronograph pulsometer representing a particularly compelling proposition. The combination of a medical complication with a high-performance flyback movement in a precious metal case places this reference in a distinct segment of the market. Its flawless, unworn state and complete documentation solidify its position as a significant and ready-to-wear example for a discerning collection, offering both immediate utility and long-term horological merit.
