Zenith
Pilot 29.1940.679/57.C808— lug 20mm

The lug width of the Zenith Pilot 29.1940.679/57.C808 measures exactly 20mm. This dimension is specific to the model and requires straps shaped to this width. The measurement should be taken with a caliper positioned perpendicular to the metal lugs that protrude from the case back.

For this model we recommend a cognac or dark brown alligator strap, which amplifies the color evolution of the oxidized bronze case. Alternatively, a matte black calf leather creates elegant contrast, while for summer daily use a slate gray NATO maintains the avionic aesthetics of the original design.

To replace the strap, use a small hammer and a watch spring bar tool (or thin metal pin) to gently push the pins that secure the strap to the case lugs. Remove the old strap, insert the new one aligning its holes with the lugs and reinstall the pins making sure they are firmly secured and the strap is centered.

Yes, but it is essential that the strap is specifically shaped for a 20mm lug width. Universal straps or different widths carry risks of premature lug wear and instability during use. We recommend always checking the strap specifications before purchase.

The durability depends on the quality of the leather and daily use. A top quality alligator or calf strap generally lasts 2-4 years if regularly maintained with specific cleaners and dried after moisture exposure. The Casati Milano atelier offers an 18-month warranty on all bespoke straps, with maintenance and replacement services.
