Zenith
Pilot 30.2430.4069/78.C811— lug 22mm

The Zenith Pilot Type 20 Extra Special reference 30.2430.4069/78.C811 has a lug width of 22mm. This measurement is integrated into the case and is a fundamental structural specification: always measure the internal space between the lugs at the spring bar attachment point to verify strap compatibility.

For a 45mm yellow gold of this historical significance, we recommend alligator in natural golden or aged ivory tones, which respects the case's prestige. A refined alternative is dark cognac calf leather, which creates a harmonious dialogue. Those preferring avionic purity may opt for clay grey or military beige NATO canvas.

The strap is secured with spring bars housed in the upper part of the lugs. Obtain a spring bar tool: insert the tip into the small lateral hole on the lug, gently lift to compress the internal spring, and extract the bar. Repeat on the other side. To install the new strap, proceed in reverse, ensuring the spring bar is correctly seated.

Yes, provided the strap's external width is actually 22mm and the spring bars are properly sized. It is essential to verify compatibility with the strap manufacturer before purchase.

The lifespan of a quality leather strap (alligator or calf) depends on use and care. On average, with daily use and standard maintenance (gentle cleaning, protection from standing water), a handcrafted strap lasts 3-5 years. Casati Milano straps offer an 18-month warranty on manufacturing defects and premature deterioration, allowing replacements at no additional cost during this period.
