What length do I need?
Measure your wrist with a tailor's tape or a piece of string, comfortably snug.

| 16.5–17.8 cm | 125 / 75 mm |
| 17.9–19.0 cm | 130 / 80 mm |

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 01 733 7705 4134
What strap size does the Oris ProPilot 01 733 7705 4134 take?
The Oris ProPilot 01 733 7705 4134 needs 23 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Oris ProPilot 01 733 7705 4134 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 01 733 7705 4134?
Yes, in 23 mm leather. On a 47 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Oris ProPilot 01 733 7705 4134?
A 23 mm calf strap, for every day. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
