Strap for Pilot's Watch Chronograph Stainless Steel / Black / Italian / Bracelet

The lug width of the IWC Pilot IW3706-06 is 20mm. This measurement corresponds to the internal distance between the two case lugs. When selecting a replacement strap, verify that the width is exactly 20mm to ensure proper seating within the case's lug holes.

For the Pilot IW3706-06, we recommend straps in alligator with vegetable tanning or chrome-tanned calf leather. Alligator emphasises the watch's instrumental character and develops a noble patina over time. Chrome-tanned calf offers visual consistency and daily practicality. For sporting use, shell cordovan guarantees superior construction density and exceptional durability.

Strap replacement requires a specific spring bar tool. Insert the flat end of the tool into the small hole on the inner side of the lug, compress the internal spring to release the lug from one eyelet, then fully extract the lug. Repeat on the other side, insert the lugs of the new strap, and ensure they click securely into position.

Yes, quality aftermarket straps are fully compatible with the Pilot IW3706-06 provided they respect the 20mm lug width and general strap width (approximately 20–22mm at the tapered end). Custom straps crafted by specialist artisans additionally allow personalisation of total length, buckle type, initials, and thread colour to your aesthetic preferences.

A premium leather strap (alligator, chrome-tanned calf, shell cordovan) with vegetable or synthetic tanning typically lasts 3–5 years with moderate daily use. Durability depends on exposure to moisture, direct sunlight, and frequency of wear. Canvas or FKM rubber straps offer longer service life (5–7 years) as they resist moisture and mechanical wear more effectively. An 18-month warranty covers manufacturing defects.
