What I'm asked about the Leroy Osmior Range LL103/3

What strap size does the Leroy Osmior Range LL103/3 take?

The Leroy Osmior Range LL103/3 needs 20 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 Leroy Osmior Range LL103/3 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 Leroy Osmior Range LL103/3?

Yes, in 20 mm leather. On a 41 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Leroy Osmior Range LL103/3?

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.
