What I'm asked about the Zenith Chronomaster 03.20410.4061/07.C772
What strap size does the Zenith Chronomaster 03.20410.4061/07.C772 take?
The Zenith Chronomaster 03.20410.4061/07.C772 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 03.20410.4061/07.C772 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 03.20410.4061/07.C772?
Yes, in 20 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Zenith Chronomaster 03.20410.4061/07.C772?
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.
