Zenith
Pilot 29.2430.4069/63.C813— lug 20mm

The lug width of the Zenith Pilot Type 20 Extra Special 45mm is 20mm. This measurement represents the distance between the two lugs on the case where the strap attaches. To verify this correctly, measure with a caliper from the center of the first lug hole to the center of the second lug hole: you will get exactly 20mm.

Dark brown alligator in cognac tone remains the most versatile choice: it imparts elegance without betraying the aviator spirit of the case. Anthracite gray alligator also integrates perfectly with the titanium. Vegetable-tanned calf straps with aging patina echo the vintage aesthetic of bomber jackets, while military gray NATO fabric straps emphasize the original instrumental character.

The strap is removed using a spring bar tool (specialized tool with a thin tip). Position the tip in the small side holes of the lugs to disengage the spring, then gently pull the strap downward. To insert the new strap, align the holes with the lugs and push until the retention spring clicks into place. If you are not experienced, consult a qualified watchmaker.

Yes, any strap with a 20mm lug width is compatible. However, always verify that the overall width of the strap does not interfere with the crown at 12 o'clock: some extra-thick straps might slightly touch the crown during rotation. The 20mm straps from milanostraps.it are specifically shaped to avoid these conflicts.

A quality alligator or calf strap, worn regularly, lasts on average 3-5 years before requiring replacement or restoration. Durability depends on sun exposure, water exposure, and frequency of use. Handcrafted straps from Casati Milano, made with premium leather and hand-stitched, remain in excellent condition beyond 5 years with minimal maintenance (periodic hydration and protection from excessive moisture).
