Longines L2.718.104.22.168 description
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.
It is unsure whether this watch ever made it to the market.
