Zenith
Pilot 05.2430.679/17.C902— lug 23mm

The lug width of the Zenith Pilot 05.2430.679/17.C902 is 23mm. This measurement refers to the distance between the two horizontal attachment points where the strap connects to the case. It is a specific construction detail of this model requiring straps manufactured explicitly for 23mm, incompatible with standard sizes such as 20mm or 24mm.

The Zenith Pilot 05.2430.679/17.C902 pairs excellently with three material categories. Genuine alligator expresses sophisticated elegance with regular texture contrasting the white dial. Vegetable-tanned calf offers daily versatility and develops ennobling patina over time. Military NATO remains the most historically authentic choice, directly aligned with French aviation heritage. Vulcanised rubber represents the contemporary solution for marine or sporting environments.

To replace the strap on the 05.2430.679/17.C902, use a spring bar removal tool. Position the forked end of the tool under the spring bar retention from inside the case, apply gentle outward pressure until the spring compresses, then extract the bar. Repeat on the opposite side. Insert the new 23mm strap, verifying that both bars are perfectly aligned with zero vertical play in the lug seats.

Any strap manufactured specifically for 23mm lug width is compatible. Milano Straps offers online a collection of 23mm straps in alligator, calf, NATO and rubber, customisable in colour, length and stitch thread. For a bespoke experience, the Casati Milano atelier creates exclusive made-to-measure straps with 18-month warranty.

Leather strap longevity depends on material, usage and climate conditions. Quality alligator, under normal wear (3-4 days weekly), maintains structural integrity between 3 and 5 years. Vegetable-tanned calf offers similar performance whilst accumulating patina. Humid environments or intense perspiration accelerate wear. Milano Straps straps benefit from artisanal warranty: stitch repair or internal reinforcement remains possible well beyond the first two years, significantly extending functional lifespan.
