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 Sport 03.3100.3600/69.C823
What strap size does the Zenith Chronomaster Sport 03.3100.3600/69.C823 take?
The Zenith Chronomaster Sport 03.3100.3600/69.C823 needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Zenith Chronomaster Sport 03.3100.3600/69.C823 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 Sport 03.3100.3600/69.C823?
Yes, in 20 mm leather. On a 41 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Zenith Chronomaster Sport 03.3100.3600/69.C823?
A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
