This triple scale chronograph is a telemeter, a tachymeter and pulsometer in one, with a spiral inner dial track that extends the ability to measure things. Carol Besler, Robb Report, 27 Sep. 2021 The track just in from the telemeter is the pulsometer, which measures heart rate, graduated for 30 pulsations.
