Strap for Pilot's Watch Doppelchronograph Platinum / White / Italian / Strap

The IWC Pilot IW3711-22 features a lug width of 21 millimetres. This dimension is measured between the pins connecting the strap to the case lugs, and represents a rare width within the contemporary IWC catalogue, found on specific Pilot models dedicated to aviation. To verify correct measurement, use a digital calliper positioned perpendicularly to the case, between the two pins.

For the IW3711-22 in platinum, we recommend alligator in vegetable tanning, cognac or dark brown hues, which develops a patina complementary to the neutral tones of platinum. Alternatively, English calfskin in pearl grey with a nickel-free deployante creates a vintage civil aviation aesthetic. For sports contexts, cordovan in dark tones offers structure and tactile density. Avoid tertiary colours (orange, green) that conflict with the monochromatic grammar of the design.

Changing the strap on an IWC Pilot requires the use of a specific tool (spring bar tool) or professional watchmaker assistance. Remove the watch from your wrist and position it with the case facing upwards. Insert the flat tip of the spring bar tool into the lug access hole, applying gentle inward pressure to release the elastic pin. Repeat for the opposite lug. To reinstall, align the new strap pins with the lugs and press until the click locks in place. If inexperienced, entrust this operation to a certified watchmaker or the Casati Milano atelier.

Yes, any strap with a 21-millimetre lug width is compatible with the IW3711-22, provided it is constructed with artisanal rigour. Milano Straps catalogues 21mm straps in noble materials (alligator, cordovan, calfskin) specifically dimensioned for this width. Always verify that the strap is equipped with a standard elastic spring bar pin, that the passant is proportioned (generally 5-7mm thickness) and that the buckle is not excessively massive relative to case proportions.

An artisanal leather strap typically lasts between 3 and 7 years with daily use, depending on the material and maintenance. Alligator in vegetable tanning ages elegantly, developing patina and periodically requiring gentle hydration with specific balms. Cordovan is more resistant but demands greater rigour in cleaning. Excessive humidity and prolonged sun exposure accelerate ageing. Casati Milano provides an 18-month warranty on all custom-made straps, with the option to replace the aged passant at no additional cost.
