What I'm asked about the Formex Diver 2100.1.7020.910
What strap size does the Formex Diver 2100.1.7020.910 take?
The Formex Diver 2100.1.7020.910 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 Formex Diver 2100.1.7020.910 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 Formex Diver 2100.1.7020.910?
Yes, in 22 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber. On a 47 mm diver I go for a full-thickness strap, not a thin one.
Which strap do you recommend for the Formex Diver 2100.1.7020.910?
Rubber if you wear it in the water; otherwise a 22 mm calf strap, full thickness. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
