Hanhart - Medische stopwatch - 1970-1979

Beautiful high-quality Hanhart stopwatch, designed especially for measuring heart rate and breathing. This stopwatch first appeared in catalogs at the beginning of the 1980s and was shown at least until 2010.

This crown-winding stopwatch is in good condition with a small blemish below and above the glass. The operation is as follows: feel the pulse (heart rate) of a person and press the crown to start. Then count 15 heartbeats and press stop. The outer ring now shows the heart rate per minute. Do the same after 5 breaths with the inner ring. An exceptional high-quality stopwatch; the movement runs accurately.

Diameter 55 mm and weight 99 grams. See the photos for details.
