Zenith
Pilot 03.2430.693/21.C723— lug 20mm

The Zenith Pilot Type 20 with reference 03.2430.693/21.C723 has a 20mm lug width. This measurement refers to the internal space of the lug where the strap is inserted. It is essential to verify this width before purchasing an aftermarket strap to ensure perfect compatibility and avoid damage to the case or strap.

The ideal material depends on use and personal preference. Mississippi alligator offers sophisticated elegance with a fine grain texture. Striped calf provides natural patina and organic aging. A NATO strap in canvas with synthetic rubber is perfect for sporty robustness. Vulcanized rubber remains the primary choice for aquatic environments. For the Type 20, we advise against excessively rigid materials that could compromise comfort given the side crown positioning.

The replacement requires a specific tool: a spring bar remover or a small precision screwdriver to extract the pins that secure the strap to the case lugs. Position the watch on a soft surface, locate the pins on both sides of the case, and gently push downward to remove them. Remove the old strap, insert the new one by aligning the holes, and reinsert the pins. For those unfamiliar with this operation, we recommend having a qualified watchmaker perform the service.

Yes, absolutely. 20mm straps are widely available in the aftermarket. Milano Straps offers a specialized collection of 20mm straps with options in premium leather, technical rubber, and NATO straps. All are tested for compatibility with the Type 20 lug width and are customizable in terms of final length, initials, and stitching thread choice. For specific requirements, Casati Milano's atelier offers fully bespoke creations.

The longevity of a leather strap depends on maintenance, use, and the quality of the leather itself. A high-quality alligator or calf strap, with proper care (avoiding prolonged exposure to moisture and direct UV rays), can last 5-8 years. Natural leather develops a characteristic patina over time, which many consider desirable. Casati Milano provides an 18-month guarantee on their work and offers restoration services to extend the strap's life beyond the first wear cycle.
