What I'm asked about the IWC Big Pilot IW5004-01

What strap size does the IWC Big Pilot IW5004-01 take?

The IWC Big Pilot IW5004-01 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 IWC Big Pilot IW5004-01 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 Big Pilot IW5004-01?

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 Big Pilot IW5004-01?

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.
