Strap for Big Pilot Laureus Charity Night Shanghai

The IWC Big Pilot IW5004-SH features a 22mm lug width. This dimension is measured between the case attachments (lug-to-lug) and is specifically calibrated for the proportions of the 46.20mm case. A 22mm strap fits perfectly into the attachment pins without lateral play.

For the Big Pilot IW5004-SH in white gold, we recommend an alligator strap in dark shades (midnight blue, anthracite) or calf leather with fine grain in cognac brown. Both materials enhance the luminosity of white gold and maintain the military aviation aesthetic. Vegetable tanning is ideal if you desire a patina that develops over time.

To change the strap, gently remove the pins that pass through the lugs. Using a spring bar tool, extract the pin toward the centre of the case; the strap will release. Align the new strap with the attachments and reinsert the pin until you hear a click. Ensure the strap is centred and presents no lateral play.

Yes, any 22mm strap is mechanically compatible with the IWC Big Pilot IW5004-SH. However, we recommend choosing a strap proportioned to the visual mass of the case (46.20mm) and to the white gold finishing. Thickness, stitching and finishes should reflect the sartorial standard of the original watch.

A natural leather strap (alligator, calf, shell cordovan) has an average lifespan of 3–5 years with daily use. Longevity depends on UV exposure, humidity and the type of tanning. Vegetable tanning tends to age more predictably and develops a desirable patina. In humid environments, it is advisable to alternate with a technical rubber strap.
