Prim mechanical pocket watches

Prim mechanical stopwatches measure time without a battery: you wind the movement with the crown, and start, stop and reset are all handled by a single button that responds even through a glove. A large dial with fine second graduations and a minute counter can be read from a distance. Stopwatches for coaches, for referees and for the workshop that will last for decades; timing on the wrist is handled by our chronographs.
