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 Pilot 05.2430.679/17.C902
What strap size does the Zenith Pilot 05.2430.679/17.C902 take?
The Zenith Pilot 05.2430.679/17.C902 needs 23 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Zenith Pilot 05.2430.679/17.C902 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 Pilot 05.2430.679/17.C902?
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 Pilot 05.2430.679/17.C902?
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.
