Strap for Pilot's Watch Doppelchronograph Platinum / Blue / Spanish

The IWC Pilot IW3713-28 has a lug width of 21 millimetres. This dimension is measured as the internal distance between the two pins that support the strap, and it is the essential technical parameter for identifying compatible straps. Incorrect measurement would lead to purchasing unsuitable straps for the case, resulting in misalignment and wear issues.

For the platinum of the IW3713-28, the most appropriate materials are alligator (natural grain and understated elegance), shell cordovan (natural patina that evolves over time), vegetable-tanned calf leather (softness and constructive transparency), and embossed technical rubber (aviation coherence). Avoid shiny materials or light tones: platinum dialogues better with deep hues and textures that catch light like the sunburst dial.

Changing the strap requires the use of a spring bar removal tool or, alternatively, a thin flat blade. Position the watch on a soft surface, locate the pins protruding from the lugs, gently push upward from below to release one of the pins, repeat for the second pin. Remove the old strap and insert the new one by aligning the holes. When the pins enter the lugs, you should feel a mechanical click closure. If you are not experienced, entrust the task to a professional to avoid scratching the platinum.

Yes, the IW3713-28 is compatible with any quality strap featuring a 21mm lug width. However, the specific geometry of the Pilot's lugs (tapered and proportioned) requires straps that respect that visual tension. Generic straps, even if correctly dimensioned, may not harmonise aesthetically with the case. For this reason, bespoke artisanal solutions guarantee aesthetic and constructive fidelity.

The lifespan of a leather strap depends on the intensity of use, climate, tanning composition, and maintenance applied. Under moderate daily use conditions and temperate climate, a quality strap in alligator or cordovan typically lasts 3-5 years before requiring replacement or restoration. Vegetable-tanned calf leather tends to wear more quickly (2-3 years). Technical rubber lasts longer (5-7 years) but degrades with prolonged direct sun exposure. Keeping the strap dry and ventilated significantly extends longevity.
