Strap for Portofino Automatic Stainless Steel / Blue

The Portofino IW3563-04 features a lug width of 20 millimetres. This measurement indicates the distance between the two lugs of the case where the strap attaches. Always measure carefully before ordering an aftermarket strap to ensure perfect compatibility.

For the Portofino IW3563-04, we recommend natural alligator in cognac or dark brown tones, or shell cordovan in burgundy for those seeking an evolving patina. Vegetable-tanned calf leather is ideal if you prefer natural ageing and sustainability. For casual wear, a soft NATO strap remains elegant without compromising sophistication.

The strap is changed by removing the spring bars that secure it to the lugs. Using a spring bar tool (or a blunt knife), gently press the bar inward to release it from one lug, then extract it completely. Repeat on the other side and remove the old strap. Insert the new strap, aligning the holes with the lugs, and reinsert the spring bars, ensuring they click firmly into position.

Yes, any strap with a 20mm lug width is compatible with the Portofino IW3563-04. Aftermarket straps offer greater choice in material, colour, and finish compared to OEM options. Ensure the total length suits your wrist (typically between 110mm and 130mm available length) and that the buckle is robust and well-constructed for longevity.

A quality leather strap (alligator, shell cordovan, or calf) typically lasts 3–5 years with daily wear, depending on climate conditions and care. Vegetable-tanned leather tends to last longer as it contains no synthetic plasticisers. Avoid wearing the strap in heavy rain or immersing the watch in saltwater. Regular maintenance (cleaning and drying) significantly extends strap lifespan.
