What I'm asked about the Zenith Defy Extreme 03.9100.9004/49.I210

What strap size does the Zenith Defy Extreme 03.9100.9004/49.I210 take?

The Zenith Defy Extreme 03.9100.9004/49.I210 needs 23 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Zenith Defy Extreme 03.9100.9004/49.I210 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 Defy Extreme 03.9100.9004/49.I210?

Yes, in 23 mm leather. On a 45 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Zenith Defy Extreme 03.9100.9004/49.I210?

A 23 mm calf strap, for every day. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
