Strap for Pilot's Watch Chronograph Stainless Steel / Black / German / Strap

The lug width of the IWC Pilot IW3706-01 is exactly 20 millimetres. This dimension, seldom found in contemporary catalogues, should be verified manually by measuring the internal distance between the two lugs at their base, where the case horn flares outward. A strap of 19 or 21 millimetres would result in mechanical instability.

Alligator is the historical material: the regular, pointed grain of American crocodile leather evokes vintage avionic instrument dials. Shell cordovan offers a contemporary choice with natural lustre. Vegetable-tanned calf allows for organic patination over time. All these materials maintain the aesthetic equilibrium between the case and the instrument.

Straps of 20mm are changed by removing the pins (lugs) that connect the strap to the case. Use a pin remover tool or counterbore, working gently from one side to the other to avoid scratching the stainless steel case. If uncertain, the Casati Milano atelier offers replacement service bespoke, with 18-month warranty.

Yes, the IWC Pilot IW3706-01 is compatible with all bespoke straps of 20mm, provided they are crafted with lugs adequate to the case attachment. Milanostraps.it offers a complete collection of 20mm straps, customisable in leathers, colours and thread, with rapid delivery.

The lifespan of a bespoke leather strap varies depending on frequency of wear and material: alligator and shell cordovan resist 4–6 years with regular wear; vegetable-tanned calf requires replacement within 3–5 years. The Casati Milano atelier guarantees 18 months, but construction quality permits significantly longer useful life if the strap undergoes periodic maintenance.
