Strap for Big Pilot Antoine De Saint Exupery Stainless Steel

The Big Pilot IW5004-22 features a lug width of 22 millimetres, which is specific to this model and essential for compatible strap selection. To verify, measure the distance between the sprung bars using a digital calliper, perpendicular to the case body. Even a 0.5mm deviation will result in undesirable lateral play.

The optimal material depends on intended usage. For visual contrast and formal elegance: black alligator with white stitching. For natural patina development and aesthetic warmth: vegetable-tanned shell cordovan. For formal-to-casual versatility: grain vitello in dark brown. For authentic aviator functionality: grey-green canvas NATO or FKM rubber strap. Thickness must be a minimum of 3.5–4mm to support the 46mm case mass.

Strap replacement requires a quality spring bar tool. Position the watch with the lug side facing upward, insert the flat end of the tool beneath the spring from the interior side, gently push downward to release the pin, then withdraw the spring. Repeat on the opposite side. When installing a new strap, align the holes with the pins, insert the first pin, push the spring until it audibly clicks, then repeat on the second side.

Yes, provided the lug width is precisely 22mm and thickness ranges between 3.5–4mm. High-quality aftermarket straps (artisanal alligator, shell cordovan, or perforated vitello) offer superior personalisation and durability compared to OEM options. Ensure the strap features robust double-thread stitching (minimum 6–8 stitches per centimetre) and a well-constructed passant.

A quality artisanal leather strap with regular daily use (5–7 days weekly) typically lasts 2–4 years before requiring replacement. Shell cordovan, due to its radial fibre structure and natural resistance, endures 5–6 years. Vitello ages more rapidly (18–30 months under intensive use). Durability factors include perspiration exposure, sunlight contact, tanning quality, and regular maintenance. A well-treated strap develops character patina and can be restored by a specialist craftsman.
