What I'm asked about the Archimede Klassik UA7939-C2.31
What strap size does the Archimede Klassik UA7939-C2.31 take?
The Archimede Klassik UA7939-C2.31 needs 18 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Archimede Klassik UA7939-C2.31 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 Archimede Klassik UA7939-C2.31?
Yes, in 18 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Archimede Klassik UA7939-C2.31?
A 18 mm box calf. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
