The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.
What I'm asked about the Citizen ProMaster JY8156-00L
What strap size does the Citizen ProMaster JY8156-00L take?
The Citizen ProMaster JY8156-00L needs 22 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Citizen ProMaster JY8156-00L 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 JY8156-00L?
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 JY8156-00L?
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.
