Pilot IW3248-01 (aka: IW324801)— lug 20mm

The lug width of the IWC Pilot IW3248-01 is 20mm. This is the distance between the two horizontal lugs (pins) that attach the strap to the case. This standard measurement allows you to pair an extensive catalogue of compatible bespoke straps without installation compromises.

For the IW3248-01 with Ceratanium case, the ideal strap is alligator or calf leather with vegetable tanning. These materials provide aesthetic elegance without competing with the neutral grey tone of the case. Colour should be dark brown (mahogany, teak) or black, to create readable contrast whilst maintaining sobriety.

Strap replacement requires a specific tool (spring bar tool) to remove the metal pins from the current strap. Once the lugs are freed, the new 20mm strap is installed identically: the two pins are inserted into the case lugs, one per side. If you lack experience, a jeweller or specialist atelier will complete the operation in minutes at minimal cost.

Yes, provided the lug width is genuinely 20mm. Any bespoke strap of quality craftsmanship made for this width fits your IWC's lug holes without modification. Compatibility depends exclusively on lug width, not on watch brand. We recommend verifying the lug width personally before purchase.

Leather strap lifespan varies according to build quality, frequency of use and environmental conditions. A high-quality artisanal strap in vegetable tanning lasts approximately 3–5 years of daily wear, developing a patina that enriches its character over time. Leather wears gradually; artisanal warranty covers construction defects and stitching for 18 months.
