Strap for Big Pilot Platinum / Blue

The lug width of the IWC Big Pilot IW5002-02 is 22mm, measured between the spring bars that attach the strap to the case. Always verify this measurement before purchasing a replacement strap: even a few millimetres of error will compromise both the fit and security of your watch.

For a watch of this calibre in platinum, a vegetable-tanned alligator strap represents the most coherent choice: the fine, uniform scale texture does not visually compete with the case, whilst its patina evolves in harmony with the platinum over time. An equally excellent alternative is shell cordovan (equine leather), offering intrinsic brilliance and resistance to wear. A dark brown vegetable-tanned calf maintains continuity with the original aviator heritage of the 1940s Beobachtungsuhr.

Strap replacement is accomplished through the spring bars located within the lugs of the case. Remove the old strap by extracting the bars laterally using a spring bar tool, then insert the bars of the new strap, ensuring they are firmly secured in both lugs. This procedure is straightforward for experienced watch enthusiasts; however, we recommend consulting a professional watchmaker if you lack experience, to avoid damaging the bars or case.

Yes, it is entirely possible and actively recommended. Milano Straps offers artisanally crafted 22mm-compatible straps with personalisation options including bespoke sizing, initials, and stitching thread selection. The essential requirement is verifying that your chosen strap has precisely 22mm lug width and appropriately dimensioned spring bars. Meeting these specifications, you will enjoy superior quality compared to official replacements, with greater creative freedom in colour matching and material selection.

Durability depends on both material and frequency of wear. An alligator or shell cordovan strap, subjected to moderate daily use, maintains structural and aesthetic integrity for 5–7 years; with regular maintenance (gentle cleaning, conditioning every 6–12 months), lifespan extends beyond 10 years. A vegetable-tanned calf strap, although less dense, provides 4–6 years of continuous wear. The 18-month guarantee offered by Casati Milano covers manufacturing defects; natural leather wear is part of its evolutionary appeal and the patina that develops over time.
