The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.

What I'm asked about the Oris ProPilot X 01 115 7759 7128-Set

What strap size does the Oris ProPilot X 01 115 7759 7128-Set take?

The Oris ProPilot X 01 115 7759 7128-Set needs 22 mm between the lugs, usually 18 or 20 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Oris ProPilot X 01 115 7759 7128-Set be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the Oris ProPilot X 01 115 7759 7128-Set?

Yes, in 22 mm leather. On a 44 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Oris ProPilot X 01 115 7759 7128-Set?

A 22 mm calf strap, for every day. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
