The pulsometer scale is a rare calibration found on the dials of chronograph watches made for those users in the medical field. Often called the 'Doctor's Dial', they allowed the instant reading of a patient's pulse rate. The Doctor would start the chronograph function at the first heartbeat, and stop it based on the count determined by the scale, in this particular example 30. The stopped chronograph hand would indicate the number of heartbeats per minute based on the scale.

This watch is a rare example of one of Ulysse Nardin's 1930s chronograph watches, featuring a stunning enamel dial with Breguet numerals and housed within a stainless steel cushion case with olive pushers for the chronograph.

The watch is presented in very good original condition and is one that can be worn for both sporting and formal events.
