Strap for Destriero Scafusia Red Gold / Black / English

The lug width of the IWC Grande Complication IW1868-11 is 22mm. This measurement is determined by the proportions of the 42.20mm case and was selected by IWC to ensure optimal aesthetic and functional balance. The measurement is taken between the inner shoulders of the case lugs.

The choice depends on intended use and aesthetic preference. For formal occasions, brown or cognac alligator complements the rose gold case beautifully. For versatile daily wear, vegetable-tanned calf develops a natural patina over time. For durability and intrinsic lustre, shell cordovan is unmatched. For sportier contexts, a high-density silk NATO strap offers practicality without compromise.

The procedure requires specific tools: a spring bar tool and a protected work surface. Position the watch case-down, insert the spring bar tool beneath one spring lug, gently lever it inward until the end releases, and retract the spring. Repeat on the other side. Remove the old strap and insert the new one, repositioning the springs. On a timepiece of this calibre, consider entrusting the operation to a professional watchmaker.

Any strap with a 22mm lug width is compatible with this model. On milanostraps.it you will find a collection of artisanal 22mm straps, customisable in leather (alligator, calf, shell cordovan), colour, initials and stitching thread. The Casati Milano atelier also offers bespoke creations with personalised WhatsApp consultation and an 18-month guarantee.

Longevity depends on the material and usage pattern. High-grade alligator, in controlled environments, may last 5-8 years. Vegetable-tanned calf, with regular maintenance (damp cloth cleaning, natural air-drying), resists 4-6 years of daily wear. Shell cordovan is the most durable, potentially exceeding 10 years owing to inherent hardness. Given a 22mm lug width and the weight of the rose gold case, it is advisable to have the strap inspected by a professional every 2-3 years and replaced upon appearance of stitch failure.
