In the early days of motor sports, the speed of racing cars was customarily determined in a stylish manner: when a milestone was passed, the second hand of the chronograph movement was switched on. When the driver passed the next milestone, the second hand was stopped, and the speed in kilometers per hour was read out from the tachymeter scale of the watch.
Our 303 series with tachymeter scale is charmingly reminiscent of past times in precisely this fashion, but is utterly contemporary as well. Thus you can precisely measure speeds between a moderate 60 km / h and a breathtaking 500 km / h accurately at any time using the method described above.
