Which strap material is best suited for the Oris Artelier 01 733 7721 4013?

How do I change the strap on the Oris Artelier 01 733 7721 4013?

Strap replacement requires a dedicated spring bar tool. Position the watch case-up, locate the upper lug, insert the tool into the slot and gently press to release the bar pin. Extract the pin and remove the old strap. Insert the new strap, align the holes with the lugs and push the pin until you hear a click. Repeat for the lower lug. If uncertain, consult a qualified watchmaker.

Spring bar pins follow industry standards. Verify that strap thickness matches the case profile (approximately 4–5mm for dress watches).
