What I'm asked about the Baume & Mercier Classima 8791

What strap size does the Baume & Mercier Classima 8791 take?

The Baume & Mercier Classima 8791 needs 18 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Baume & Mercier Classima 8791 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 Baume & Mercier Classima 8791?

Yes, in 18 mm leather. On a 39 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Baume & Mercier Classima 8791?

A 18 mm calf strap, for every day. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
