What I'm asked about the IWC Pilot IW3922-02

What strap size does the IWC Pilot IW3922-02 take?

The IWC Pilot IW3922-02 needs 21 mm between the lugs, usually 18 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the IWC Pilot IW3922-02 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 IW3922-02?

Yes, in 21 mm leather. On a 43 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the IWC Pilot IW3922-02?

A 21 mm box calf. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
