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 EO2023-00A
What strap size does the Citizen ProMaster EO2023-00A take?
The Citizen ProMaster EO2023-00A needs 18 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Citizen ProMaster EO2023-00A 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 EO2023-00A?
Yes, in 18 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 37 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 18 mm: write to me and I'll make it.
Which strap do you recommend for the Citizen ProMaster EO2023-00A?
Rubber if you wear it in the water; otherwise a 18 mm calf strap, full thickness. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
