Strap for Big Pilot Rose Gold / Black / Arije

The lug width of the IW5004-16 is 22mm. This measurement is specific to the Big Pilot model with a 46.2mm case diameter and allows the use of aftermarket straps of comparable construction quality. To verify the measurement, use a digital calliper positioned between the inner lug attachments.

For the Big Pilot in rose gold, we recommend alligator in warm brown hazelnut tones, black or dark cognac calf leather, or shell cordovan in natural cognac colour. These materials reflect the luxury of the precious case and develop an elegant patina over time. Avoid straps that compete visually with the authority of the instrument.

Use a spring bar tool (specialised tool) to extract the retaining pins from the lugs. Position the watch on a soft surface to avoid scratches. Compress the pin slightly towards the centre, remove the old strap and insert the new one, aligning it with the lugs. Ensure the pin is fully seated on both sides before releasing. If you lack experience, consult a professional watchmaker.

Yes, any strap with a 22mm lug width will fit the IW5004-16 physically. However, aesthetic compatibility depends on the case design: ensure that the thickness and width of the strap visually balance the 46.2mm diameter. Straps that are too thin may create visible gaps; disproportionate straps will alter the design balance.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with moderate daily wear. Durability depends on exposure to moisture, perspiration and sunlight. Shell cordovan lasts longer due to the natural properties of horse hide. With proper maintenance (regular cleaning, drying, annual conditioning), the strap can last over 5 years. The buckle and deployant clasp, if of quality, last indefinitely.
