Strap for Pilot's Watch Doppelchronograph Yellow Gold / Black / French

The lug width of the IWC Pilot IW3713-16 is 21 millimetres. This is the space between the case lugs where the strap attaches. To verify strap compatibility, measure the distance between the two lugs: it must be exactly 21 millimetres. Do not confuse this measurement with the case diameter, which is independent of the lug width.

For the yellow gold IWC Pilot IW3713-16, vegetable-tanned alligator is the natural choice: the fine grain reflects the warm tone of the gold and the patina evolves in parallel with the case. Cordovan in burgundy or dark brown tones offers durability and pleasant contrast. Vegetable-tanned calf is the most understated alternative, with uniform surface and progressive patina development.

To change the strap, position the watch on a soft pad or cloth to protect the case. Use a spring bar tool (instrument with a rounded tip) to press upward on the elastic lugs of the case, releasing one end of the strap at a time. Insert the new lugs in the correct lug width (21mm) and verify that they fit completely into the slots. Proceed with care to avoid scratching the yellow gold case.

All straps with a 21 millimetre lug width are compatible with the IWC Pilot IW3713-16. On milanostraps.it you will find a complete collection of 21mm straps in alligator, Cordovan, calf and other materials, ready for shipment and customizable in length and finishes. Always verify that the lug width is exactly 21 millimetres before purchase.

A high-quality leather strap (alligator, Cordovan, calf) has a lifespan of 3-5 years with moderate daily use. Longevity depends on frequency of use, environmental humidity, perspiration and maintenance. Prolonged exposure to moisture reduces lifespan; conversely, dry environments promote preservation. Vegetable tanning ages better than chrome tanning, developing progressive patina. Casati Milano straps include an 18-month warranty and can be replaced at a reduced cost.
