How an automatic watch works
Your wrist gives it energy. A spring saves it. A tiny balance sets the rhythm. Follow the journey inside an automatic watch, one pencil drawing at a time.
Tissot · PRC 200
Ref. T0554271105700
The Tissot PRC 200 Automatic Chronograph Black takes a 23 mm strap: measure between the lugs and that is the only number you need. Built for water, it wears naturally on rubber or a nylon NATO; a leather strap keeps it for dry days. With a 44 mm case and 200 m of water resistance, a thicker strap balances the case. Automatic movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
