Crocodile Strap for IWC Portofino 37

The 37mm IWC Portofino Automatic is the midsize version of the line, a slim dress watch that asks for a strap in proportion to its smaller case. This build answers with light brown crocodile, cut to 75/125mm and tapered to a 16mm buckle so it stays delicate rather than overwhelming the watch.

Why these choices

The Portofino is a dress watch, and crocodile is the classic dress leather. Its raised tile pattern reads formal without shouting, and over time the hand-finished skin softens and takes on a hand-rubbed patina. Light brown keeps the pairing warm and daytime-friendly, a step away from the expected black. If you want the same look on your own watch, start with a crocodile watch strap.

Scale on the smaller Portofino matters. The full-size Portofino wears a broader strap; the 37mm midsize looks best with a narrower cut that finishes at a 16mm buckle, which is how this one was built. A brown leather strap in this proportion flatters the slim case instead of fighting it.

It uses regular spring bars, removed with a tool rather than a quick-release tab, which sit more securely for a strap you are not swapping daily. The exact leather here is our light brown crocodile strap, and like every strap it is cut to your watch and wrist.
