The present watch is a rare example featuring a dial specifically calibrated for pulsations. It is also named as “doctor’s watch” due to the pulsation scale on the dial; the scales are calibrated to show heart rate after counting 30 pulses. This particular model was especially adjusted with a half chronometer balance to warrant further precision and accuracy to the watch.
