What I'm asked about the Citizen ProMaster BJ7150-09L

What strap size does the Citizen ProMaster BJ7150-09L take?

The Citizen ProMaster BJ7150-09L 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 Citizen ProMaster BJ7150-09L 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 BJ7150-09L?

Yes, in 20 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 40 mm diver I go for a full-thickness strap, not a thin one.

Which strap do you recommend for the Citizen ProMaster BJ7150-09L?

Rubber if you wear it in the water; otherwise a 20 mm calf strap, full thickness. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
