What I'm asked about the Citizen ProMaster BY3005-56G

What strap size does the Citizen ProMaster BY3005-56G take?

The Citizen ProMaster BY3005-56G 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 ProMaster BY3005-56G 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 ProMaster BY3005-56G?

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 46 mm diver I go for a full-thickness strap, not a thin one.

Which strap do you recommend for the Citizen ProMaster BY3005-56G?

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.
