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 Zenith Chronomaster Original 03.3200.3600/21.C903
What strap size does the Zenith Chronomaster Original 03.3200.3600/21.C903 take?
The Zenith Chronomaster Original 03.3200.3600/21.C903 needs 19 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Zenith Chronomaster Original 03.3200.3600/21.C903 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 Zenith Chronomaster Original 03.3200.3600/21.C903?
Yes, in 19 mm leather. On a 38 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Zenith Chronomaster Original 03.3200.3600/21.C903?
A 19 mm box calf. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
