Strap for Pilot's Watch Doppelchronograph Stainless Steel / Black / Italian / Strap

The lug width of the IWC Pilot IW3713-02 is 21 millimetres. This measurement is precisely specified by IWC for this model and ensures a harmonious fit with the 42mm case. To verify compatibility, measure the internal space between the two strap attachment points on the case using a digital caliper.

The ideal strap depends on intended use: alligator on vegetable tanning amplifies the austere aesthetic and suits formal contexts; brushed vitello in navy blue dialogues with the Bauhaus design philosophy; NATO in charcoal grey restores the original tactical function; shell cordovan develops an elegant patina with age. All are available in compatible 21mm width.

The Pilot IW3713-02 uses standard lugs. To replace the strap: remove the watch from your wrist, locate the attachment points (lugs) on both sides of the case, insert the lug removal tool under the metal lever and press outward until the lug disengages. Reverse the process with the new strap, ensuring the passants are correctly aligned.

Yes, provided the lug width is exactly 21mm. High-quality aftermarket straps (alligator, vitello, NATO, cordovan) are fully compatible with the Pilot IW3713-02. Verify the strap width at the passant points to prevent micro-movement or excessive tension.

A quality leather strap (alligator, vitello, or cordovan on vegetable tanning) typically lasts 3-5 years with daily wear, accounting for natural material degradation and buckle or deployante wear. Lifespan increases if you rotate straps across multiple watches or store it during months of reduced use. Atelier Casati Milano provides an 18-month guarantee on all bespoke straps.
