IWC
Pilot IW3706-22— lug 20mm

The lug width of the IWC Pilot IW3706-22 is 20mm. This measurement refers to the distance between the two attachment points where the strap is secured. Always measure between the centres of the attachment holes on your watch case to ensure absolute compatibility.

The choice depends on intended use and personal style. Alligator with vegetable tanning offers authentic patina and flexibility; vegetable-tanned calf provides tactile warmth and noble ageing; NATO in nylon is the functional choice for genuine avionic use; FKM rubber is ideal if you refuse compromise between aviation and water sports. All materials are compatible with 20mm lugs.

The Pilot IW3706-22 strap is secured via two spring bars running horizontally. Using a spring bar tool, push the bar inward to release the internal spring, then extract the bar and old strap. Insert the new strap by aligning its holes with the lugs, reinsert the spring bar and verify complete locking. No case disassembly is required.

Yes, absolutely. Any strap with 20mm lug width is compatible with the IW3706-22. High-quality artisanal aftermarket straps often offer superior materials and finishes compared to original straps, allowing you to personalise your watch's appearance while maintaining complete technical compatibility.

A high-quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years with moderate daily use, provided regular maintenance. Constant exposure to humidity, perspiration and UV rays shortens lifespan. Artisanal straps come with 18-month warranty and can be regenerated or replaced; NATO nylon lasts considerably longer, up to 7–10 years.
