Zenith
Pilot 29.2430.679/21.C753— lug 22mm

The lug width of the Zenith Pilot 29.2430.679/21.C753 is exactly 22mm. To verify this measurement, use a digital caliper positioned perpendicularly between the lugs of the currently fitted strap. Do not confuse lug width (22mm) with case diameter (45mm): these are independent dimensions that determine strap compatibility.

For this model we recommend cognac brown alligator (to emphasize the natural bronze patina), grey-taupe calf (for sophisticated contrast), or navy blue and dark grey NATO (to underscore the aeronautical DNA). Alligator offers organic texture that evolves over time, calf guarantees versatility and vegetable tannin patina, while NATO and rubber ensure authentic tool-watch character.

Use a pin remover tool or small screwdriver to gently push the spring bar that connects the case to the strap. Work on a clean surface to avoid losing components. Align the new 22mm strap with the lugs and reinsert the spring bar, ensuring it is fully secured. If unsure, the Casati Milano atelier offers professional strap changes and adjustment.

Yes, any strap sized for 22mm lugs is compatible with the Zenith Pilot 29.2430.679/21.C753. Always verify that the manufacturer specifies '22mm' in the technical specifications. We recommend artisanal alligator or vegetable tannin calf straps that respect the titanium-bronze case geometry and evolve naturally over time, creating aesthetic synergy with the case patina.

A quality leather strap (alligator or vegetable tannin calf) typically lasts 3-5 years with daily use, provided proper maintenance: avoid prolonged water and moisture, store in a dry location, treat periodically with neutral balm. Leather wears naturally, developing patina and surface creasing that increase character. The Casati Milano atelier offers an 18-month warranty on bespoke straps and recommends replacement when the strap shows structural failure.
