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 · TT1
Ref. 01735775241540742406FC
The Oris TT1 Day Date Stainless Steel / Black / Rubber takes a 24 mm strap: measure between the lugs and that is the only number you need. We list 18 straps in that width. With a 42 mm case and 100 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.
Width is a starting point. Check the case and end fittings before choosing.
