The Longines Asthmometer-Pulsometer Chronograph demonstrates the fact that the precision of a chronograph is necessary not only in sport. This new instrument is based on a model brought out in 1963 which was intended essentially for medical use. The new product not only shows the time but also measures heart rate and respiration. While the pulse and respiration scales can be extremely useful in a sports context, during training sessions for example, they also provide a doctor with valuable information as to the patient’s vital functions.
The Longines Asthmometer-Pulsometer Chronograph echoes the principal design features of the product on which it is based. The red heart rate scale and the blue respiration scale can be easily read off from the outer edge of the silvered dial. The 12 numeral and the eight gilded applied indices blend with the hands and the counter circles, which are also gold-plated. The steel case, which has a diameter of 38.50 mm like the original model, is enhanced by the bevelling of the horns. A black alligator strap adds the final touch to this doctor’s watch.
