What I'm asked about the IWC Pilot IW3791-04

What strap size does the IWC Pilot IW3791-04 take?

The IWC Pilot IW3791-04 needs 22 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the IWC Pilot IW3791-04 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 IWC Pilot IW3791-04?

Yes, in 22 mm leather. On a 46 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the IWC Pilot IW3791-04?

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.
