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.
SevenFriday
Ref. PS3/03
The SevenFriday PS3/03 AKA "CCO" takes a 28 mm strap: measure between the lugs and that is the only number you need. With 100 m of water resistance, a strap of medium thickness keeps the balance. Automatic movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
