LONGINES – The Longines Pulsometer Chronograph

LONGINES – The Longines Pulsometer Chronograph

0 1547

Longines draws upon its rich watchmaking heritage in reviving one of its 1920s models that was essentially used for medical purposes. Its pulsometric scale meant this monopusher chronograph made it possible not only to measure time, but also the heartbeat in a simple, reliable and accurate manner. Pulse measurements used to be taken over a 60-second period and involved counting the exact number of heartbeats during that entire time. The procedure was not always very rigorous and the creation of the pulsometer served to remedy such potential imprecision. Like the original model, The Longines Pulsometer Chronograph uses the chronograph hand sweeping around the pulsometric scale to indicate the patient’s pulse on the dial after just 30 beats.
