Strap for Big Pilot 43 Top Gun

The lug width of the Big Pilot IW3298-01 is 21 millimetres. This is the distance between the inner ends of the case lugs. When selecting a compatible strap, always specify 21mm even though the strap itself may have slightly variable width thanks to adjustable passants.

There is no single answer—it depends on usage and personal preference. For formal contexts, dark brown alligator maintains the technical sobriety of the watch. For a sportier approach, vegetable-tanned calf or a grey NATO strap reflect the aviator heritage. Personalised consultation available at Casati Milano.

The process requires a spring bar tool. Position the watch on a stable surface, insert the flat end of the tool into the lug hole, apply gentle downward pressure to release the pin, remove the old strap. Insert the new strap by sliding the pin through the passants. Verify that the pin is fully seated before wearing the watch.

Yes, artisanal straps compatible with the 21mm lug width are available online at milanostraps.it, made from alligator, vegetable-tanned calf, shell cordovan and other materials. They offer customisation in sizing, initials and stitching thread choice. For fully bespoke straps, Casati Milano creates custom pieces with direct consultation and 18-month warranty.

A quality artisanal leather strap lasts between 3 and 5 years with regular wear. Alligator and shell cordovan, being denser leathers, tend to age more slowly. Vegetable-tanned calf develops a patina that enhances its character over time, even after 7-8 years of use. Lifespan depends on UV exposure, humidity and frequency of wear.
