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.
Vacheron Constantin · Égérie
Ref. 4605F/000RB496
The Vacheron Constantin Égérie Self-Winding 35 Pink Gold / Diamond / Silver takes a 16 mm strap: measure between the lugs and that is the only number you need. We list 9 straps in that width. A dress watch by proportion: a slim leather strap, plain or lightly stitched, keeps the line clean. With a 35 mm case and 30 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.
Width is a starting point. Check the case and end fittings before choosing.
