Strap for Pilot's Watch Chronograph Ceramic / English / Strap

The lug width is 20 mm for the entire IW3705-03 model. This measurement is standard and allows compatibility with all artisanal straps designed for the 20 mm size. Measurement is taken between the inner holes of the case, perpendicular to the dial.

Dark brown alligator (mahogany tone) represents the ideal choice for the aviator aesthetic of the model. Alternatively, vegetable-tanned calf imparts character with a more pronounced patina. For humid environments or water sports, technical rubber maintains functionality. NATO fabric straps remain versatile for daily wear.

Position the watch on a soft mat and locate the lug pins (spring bars). Use a spring bar tool to compress the pin and gently lever out the old strap. Insert the new strap by aligning the pins into the case lugs and release the tool. Verify the strap is fully seated and symmetrical.

Yes, an aftermarket strap with 20 mm lug width is fully compatible. MilanoStraps offers artisanal straps specific to this size, constructed with quality equivalent to or exceeding OEM straps. Third-party use does not invalidate warranty, provided the watch sustains no damage during replacement.

A quality leather strap (alligator or calf) lasts 3–5 years with regular use and proper maintenance. Longevity depends on humidity, frequency of use, and personal perspiration. Leather fears water pooling and extreme temperatures. Conditioning treatments can extend lifespan to 8–10 years.
