What I'm asked about the Citizen Sport Luxury BY1010-57H

What strap size does the Citizen Sport Luxury BY1010-57H take?

The Citizen Sport Luxury BY1010-57H 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 Citizen Sport Luxury BY1010-57H 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 Citizen Sport Luxury BY1010-57H?

Yes, in 22 mm leather. On a 43 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Citizen Sport Luxury BY1010-57H?

A 22 mm calf strap, for every day. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
