Strap for Pilot's Watch Mark XVI Stainless Steel / Black / Bracelet

The lug width of the IWC Pilot IW3255-04 is 20mm, measured internally from lug to lug (shoulder to shoulder). This width ensures compatibility with the majority of standard straps and allows smooth passage through the case lugs.

For the IW3255-04 we recommend a matte alligator in cognac tones for formal wear, vegetable-tanned leather for natural ageing, or a canvas NATO in ecru for daily sports use. The choice depends on intended use: office, personal collection, or outdoor pursuits.

Remove the strap by unscrewing the spring bars (spring lugs) using a dedicated tool. Position the watch with lugs facing upwards, gently compress the spring bar at one end to release the collar, remove the old strap and insert the new one. Verify that the spring bar is securely anchored on both sides. If uncertain, entrust the task to Casati Milano.

Yes, provided the lug width is exactly 20mm. Quality artisanal aftermarket straps often offer superior finishes, leathers and customisation compared to originals, whilst maintaining full mechanical compatibility. Always verify thickness specifications to avoid rubbing on the case.

A quality leather strap (alligator, calf, shell cordovan) lasts 3 to 7 years with daily use, depending on cleaning frequency, UV exposure and humidity. Vegetable-tanned leather ages magnificently, developing a protective patina. Casati Milano guarantees 18 months on all custom straps.
