What I'm asked about the Zenith Pilot 11.2240.405/21.C773

What strap size does the Zenith Pilot 11.2240.405/21.C773 take?

The Zenith Pilot 11.2240.405/21.C773 needs 22 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Zenith Pilot 11.2240.405/21.C773 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 Zenith Pilot 11.2240.405/21.C773?

Yes, in 22 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 Zenith Pilot 11.2240.405/21.C773?

A 22 mm box calf. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
