What I'm asked about the Unimatic Modello Quattro UC4

What strap size does the Unimatic Modello Quattro UC4 take?

The Unimatic Modello Quattro UC4 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 Unimatic Modello Quattro UC4 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 Unimatic Modello Quattro UC4?

Yes, in 22 mm leather. On a 40 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

Which strap do you recommend for the Unimatic Modello Quattro UC4?

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