What I'm asked about the Unimatic Modello Tre U3-U
What strap size does the Unimatic Modello Tre U3-U take?
The Unimatic Modello Tre U3-U needs 22 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Unimatic Modello Tre U3-U 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 Tre U3-U?
Yes, in 22 mm leather. On a 42 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Unimatic Modello Tre U3-U?
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.
