Strap Guide: IWC Portofino Automatic Moon Phase 37 Year of the Snake

Strap Guide written by @watch.link. Thank you, Jessica!

Introduction

IWC welcomed the 2025 Lunar New Year with this special edition watch: the Portofino Automatic Moon Phase 37 Year of the Snake. Limited to just 500 examples, this charming watch carries a deep burgundy red dial with 18-carat 5N gold hands and appliques, along with a matching serpent-shaped rotor (in 5N gold). Not only is this watch gorgeous front-to-back, but it also houses IWC's automatic calibre 32800. With an impressive 120-hour power reserve, this Portofino is an incredible grab-and-go piece to start the mornings with.

Here are a couple of strap options to pair with this scarlet time-teller:

Cream Epsom Slim

This is my daily driver pairing for my Portofino. Simple and clean ー the Cream Epsom adds an understated elegance to the watch, bringing casual class without fanfare or excess. Its muted tone blends effortlessly with any outfit (although the burgundy of the IWC may be a bit more selective), and the Epsom leather adds a subtle texture that keeps the look engaging.

Matte Cognac Alligator Flank Stitchless

Throw an Alligator Flank Stitchless strap on any watch, and it’ll be an automatic improvement! Though it does become a step dressier, there are a few key details that allow this strap to strike a balance between casual and refined. First, its slim profile and lack of padding. Second, the clean, stitchless design. These two elements combined make this strap an ideal choice, whether you’re cosying up by the fireplace during winter or ringing in the next Lunar New Year with loved ones.

Black Rubber CTS

Even though the Portofino leans towards the dressier end of the spectrum, it still boasts 30 meters of water resistance. On those days when you happen to be out and about and desire a more durable or waterproof strap, the Black Rubber CTS (cut-to-size) strap is perfect for keeping that clean look while weathering the elements.

Lavender Chevre Slim

Despite being a slightly unconventional combination, this might be my favourite of the batch. The light lavender of the strap complements the deep burgundy of the dial just right, in a way that brings out the best in both. The slim profile and the softness of the Chevre make this strap immediately comfortable right out of the packaging, and simply a delight to wear.

Light Grey Nubuck Slim

Probably one of the best all-rounder straps in the Delugs collection, the Light Grey Nubuck Slim pairs with just about any watch you can throw at it. This Portofino is no exception. The light grey hue tempers the boldness of the dial, allowing the red and gold portions to be the star of the show. And as for the leather, its status as a fan favourite becomes immediately clear the second you put it on.
