Chronograph watch with 3 counters
Generally speaking, an instrument which counts and/or records. Chronograph totalisers are counters which indicate the number of revolutions made by the chronograph hand: 30, 45 or 60 minute totaliser / 12 hour totaliser.
Pocket chronographs are sports counters which indicate neither the hours nor minutes but short intervals measured to the nearest fifth, tenth or hundredth of a second.
