What I'm asked about the Oris ProPilot X 01 400 7778 7150-07 7 20 01TLC
What strap size does the Oris ProPilot X 01 400 7778 7150-07 7 20 01TLC take?
The Oris ProPilot X 01 400 7778 7150-07 7 20 01TLC needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Oris ProPilot X 01 400 7778 7150-07 7 20 01TLC 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 01 400 7778 7150-07 7 20 01TLC?
Yes, in 20 mm leather. On a 39 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Oris ProPilot X 01 400 7778 7150-07 7 20 01TLC?
A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
