To power the new Villeret Chronographe Pulsomètre, Blancpain opted for a self-winding movement a beating at the rate of 36,000 vibrations per hour (5 Hz) and equipped with a flyback chronograph function. This is the same 13-ligne manufacture-made calibre used for the Fifty Fathoms Bathyscaphe Flyback Chronogrape presented early this year at Baselworld 2014.
Comprising 322 parts including a silicon balance spring, the movement is equipped with a vertical clutch as well as a chronograph mechanism controlled by a column wheel. The flyback function enables instant chronograph resetting and restarting by pressing the pusher positioned at 4 o’clock.
In this case, the watch features a pulsometer function serving to easily check a heart rate, a first time for a Blancpain timepiece.
The chronograph hand in association with the specially graduated scale makes it possible to display the patient’s heart beat directly on the dial by just starting the chronograph and stopping it after 30 heartbeats: the chronograph hand will indicate the exact number of heartbeats per minute.
A precious and exclusive touch is represented by the cambered white Grand Feu enamel dial with enamel-painted Roman numerals. The chronograph 30-minute and 12-hour counters are symmetrically positioned at 3 and 9 o'clock respectively while the date window can be found just above the 6 numeral.
On the back, the transparent sapphire crystal unveils the automatic movement with its decorated oscillating weight.
The 43.6 mm red gold case of the Villeret Chronographe Pulsomètre (ref. 6680F-3631-55B) is matched to a brown alligator leather strap.
