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.

  • With a continuous-action counter, the hand makes a slow and continuous movement.
  • With a semi-instantaneous counter, the hand begins to move at the 58th second and jumps to the 60th second.
  • With an instantaneous counter, the hand jumps straight to the 60th second.
