Strap for Big Pilot Platinum / Black / Wempe

The lug width of the IWC Big Pilot IW5004-34 is 22mm. This measurement represents the distance between the two case lugs where the strap attaches. It is a critical parameter when purchasing compatible straps: an incorrectly sized strap will either create gaps or require force to install.

For the platinum Big Pilot, we recommend a cognac or chocolate brown alligator strap with vegetable tanning: the regular texture and natural patina enhance the case's noble metal without visual competition. For formal settings, soft calf leather in dark tones. For daily instrument use, NATO or FKM rubber offer durability and quick changes.

Obtain a spring bar tool (a dedicated tool for removing the metal retaining springs). Insert the thin, flat end under the spring inside the lug and gently lever upward until the spring retracts, then remove the metal bar. Repeat on the opposite side. Align the new strap's holes with the case lugs and reinsert the springs. Confirm both springs are fully seated before wearing.

Yes, provided the strap has precisely 22mm lug width. Quality aftermarket straps often offer advantages over original equipment: wider material selection, bespoke construction, competitive pricing. Milano Straps manufactures 22mm straps specifically compatible with the Big Pilot, customisable in length and finishing details.

Longevity depends on leather quality, usage patterns and maintenance. An artisanal alligator or calf strap with vegetable tanning lasts 3–5 years with regular daily wear. Vegetable-tanned leather develops a natural patina that increases aesthetic value over time. Avoid prolonged exposure to salt water and dry quickly after perspiration. Annual conditioning will significantly extend strap lifespan.
