What I'm asked about the Formex Pilot 1100.1.3040.223
What strap size does the Formex Pilot 1100.1.3040.223 take?
The Formex Pilot 1100.1.3040.223 needs 22 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Formex Pilot 1100.1.3040.223 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 Formex Pilot 1100.1.3040.223?
Yes, in 22 mm leather. On a 47 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Formex Pilot 1100.1.3040.223?
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.
