Strap for Portofino Automatic / Stainless Steel / White / Strap

The lug width of the IWC Portofino IW3533-22 is 20 millimetres. This measurement is critical for compatibility: any strap must have end links with an internal width of 20mm. To verify, position a digital calliper between the internal lugs of the case.

For the Portofino IW3533-22, alligator or shell cordovan straps represent the finest aesthetic and constructive choice. Alligator offers regular texture and harmonious dialogue with stainless steel. Shell cordovan guarantees superior density and dramatic patina development. For daily versatility, vegetable-tanned calf is the intelligent solution.

The Portofino IW3533-22 strap is changed using a dedicated tool (spring bar tool). Position the tool in the lower recess of the spring and push upward to compress the spring, then remove the old strap. Insert the new strap aligning the end links with the lugs, release the tool and verify attachment.

Yes, any strap with 20mm lug width is compatible with the Portofino IW3533-22. The artisanal straps from milanostraps.it are constructed for this measurement and are fully compatible without adaptation. Artisanal quality also guarantees superior finishing compared to OEM straps.

The lifespan of a leather strap depends on material and use. An alligator or shell cordovan strap, with regular maintenance (avoiding excessive moisture and direct sunlight), lasts 5-8 years. Vegetable-tanned calf has similar longevity if properly maintained. Rubber straps last 7-10 years whilst maintaining consistent elasticity.
