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.
Oris · Big Crown
Ref. 0175477794065SET
The Oris Big Crown Pointer Date Cervo Volante / Blue takes a 19 mm strap: measure between the lugs and that is the only number you need. We list 7 straps in that width. With a 38 mm case and 50 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.
