Strap for Pilot's Watch Mark XVIII Le Petit Prince

The lug width of the IWC Pilot IW3270-04 is 20 millimetres. This width is specific to this model and allows for a wide choice of aftermarket straps, both in leather and fabric. To verify it accurately, use a digital calliper positioned between the two lugs, at the widest point closest to the case.

For the IW3270-04, the black alligator strap represents the conservative choice, faithful to original IWC equipment. If you desire alternatives, burgundy shell cordovan offers sophistication without compromise, whilst vegetable-tanned calf in aged brown ensures comfort and a patina that improves over time. NATO straps provide a pragmatic solution for those who change frequently based on activity.

Use a dedicated tool called a spring bar tool. Position the watch with the lug facing upwards, insert the bifurcated tip of the tool into the gap between the lug spring and the case, push gently upwards to release the spring, then extract the lug. Repeat on the other side. Proceed in reverse to fit the new strap. If you lack experience, consult a professional watchmaker or Casati Milano atelier.

Yes, absolutely. The 20mm lug width is a standard width that allows for an enormous choice of aftermarket straps. Once you have verified that the strap is compatible with the 20mm width, you can fit it without any modification to the case. Milanostraps.it offers a complete range of artisanal 20mm straps, customisable according to your preferences for leather, colour and stitching.

The lifespan depends on the quality of the leather, frequency of use and maintenance. An alligator or shell cordovan strap of good quality typically lasts 3-5 years with daily wear. Vegetable-tanned leather tends to last longer (5-7 years) due to greater fibre robustness. The Casati Milano atelier offers an 18-month warranty on all artisanal straps, covering manufacturing defects.
