What I'm asked about the Archimede Sporttaucher UA8974BM-TB-A5.5

What strap size does the Archimede Sporttaucher UA8974BM-TB-A5.5 take?

The Archimede Sporttaucher UA8974BM-TB-A5.5 needs 20 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Archimede Sporttaucher UA8974BM-TB-A5.5 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 Sporttaucher UA8974BM-TB-A5.5?

Yes, in 20 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 Archimede Sporttaucher UA8974BM-TB-A5.5?

A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
