Frequently asked questions
What is the lug width of the IWC Pilot IW3705-07?
The lug width of the IWC Pilot IW3705-07 is 20 millimetres. This measurement is standard for the model and ensures compatibility with any strap manufactured for 20mm lugs, from alligator models to fabric NATO straps. Correct measurement is performed by positioning a calliper between the inner edges of both lugs, laterally and perpendicular to the case.
What is the best strap for an IWC Pilot IW3705-07?
The best strap depends on intended use. For formal elegance, we recommend black alligator or vegetable-tanned leather in deep cognac brown. For sporting and instrumental practicality, NATO straps in charcoal grey or dark blue nylon are ideal. Shell cordovan represents the compromise between sophistication and longevity. All available in 20mm size at MilanoStraps.
How do you change the strap on an IWC Pilot IW3705-07?
The process is straightforward: use a spring bar tool to remove the lug pins on both sides of the case. Insert the pin into the new strap, aligning it correctly with the lugs. Ensure the pins are fully inserted and the strap is securely fastened before wearing the watch. If preferred, Casati Milano offers a personalised strap change service.
Is an aftermarket strap compatible with the IWC Pilot IW3705-07?
Yes, any strap with a 20-millimetre lug width is compatible with the IW3705-07. MilanoStraps supplies a wide selection of artisanal aftermarket straps, from alligator to calf, shell cordovan to NATO, all tested for geometric compatibility and durability. The 18-month warranty on bespoke Casati Milano straps guarantees certified construction quality.
How long does a leather strap last on an IWC Pilot IW3705-07?
Longevity depends on leather quality and frequency of use. An artisan-crafted alligator or shell cordovan strap typically lasts 3-5 years of regular use, developing a natural patina that increases aesthetic value. Vegetable-tanned leather, being softer, requires replacement every 2-3 years. Fabric NATO straps last longer (5-7 years) but require periodic cleaning. Casati Milano offers regeneration and repair services.
