What I'm asked about the Zenith Defy 04.9000.8812/00.R920
What strap size does the Zenith Defy 04.9000.8812/00.R920 take?
The Zenith Defy 04.9000.8812/00.R920 needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Zenith Defy 04.9000.8812/00.R920 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 04.9000.8812/00.R920?
Yes, in 20 mm leather. On a 44 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Zenith Defy 04.9000.8812/00.R920?
A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
