Watch Straps for IWC – Lug Widths and Best Straps

IWC Schaffhausen is one of Switzerland's most respected watchmakers, known for combining the functionality of pilot's watches with the elegance of dress watches. The Big Pilot, Portugieser and Aquatimer are its most sought-after models – and all of them take standard watch straps.

An IWC Portugieser on a classic black leather watch strap is the definitive elegant combination. A Big Pilot on a thick brown leather strap delivers the authentic aviator feel. And the Aquatimer pairs perfectly with a rubber watch strap for active use in and around water.

All our watch straps fit IWC models with standard lugs – simply choose the right lug width below.

Tip: fitting a 21 mm lug width

Several IWC Pilot's Watch models have a 21 mm lug width – an unusual size. In practice, a 20 mm or 22 mm watch band works well if you choose a softer material such as leather or rubber. We recommend squeezing in a 22 mm strap rather than leaving a 1 mm gap.
