Inspired by a mainly medical timepiece from the early 1920s, the Longines Pulsometer Chronograph measures the number of heartbeats, in addition to the time. The original model of this reissue was used as an instrument by the medical profession to calculate a patient's heart rate reliably and quickly.

At the time, the pulse measurement was taken over a period of 60 seconds during which it was necessary to precisely calculate the number of the patient's heartbeats. As this approach is not entirely trustworthy, the creation of pulsometer overcame inaccuracies. Indeed, this function provides a simple, reliable and rapid heart rate reading. The chronograph hand, coupled with the pulsometric scale, clearly indicates the patient's heart rate on the screen after only 30 pulses.

The Longines Pulsometer Chronograph offers sober elegance like the model that inspired it. The white lacquered dial is adorned with painted black Arabic numerals which subtly enhance "Breguet"-type blued steel hands, while the red of the pulsometric scale stands out in perfect refinement. The transparent steel case back with a diameter of 40 mm reveals the minutiae of the column wheel movement produced exclusively for Longines. A brown leather strap harmoniously completes this model.
