Very rare soviet ultra slim doctors watch Raketa from 1980s with special scale for heart rate measurements. To measure heart rate, start counting pulsations at 60 or 30 seconds base and when pulsation reached 15 pulses read on the scale your heart rate, very simple and clever idea. This is a profession watch and can be worn by both gents or ladies.
