Strap for Portofino Automatic Rose Gold / Champagne

The IWC Portofino IW3563-10 features an exactly 20-millimetre lug width. This measurement represents the space between the lugs' extremities on the case and directly governs strap compatibility. Any 20mm strap will insert correctly into the watch's spring bars without requiring forced adjustments.

For an IWC Portofino in rose gold, chocolate brown or burgundy alligator represents the most noble choice: its regular grain enhances the case finish without competing with it. Vegetable-tanned calf in deep colours offers superior comfort and a natural patina. Shell cordovan, whilst rare, creates unique chromatic effects. For casual contexts, a military nato or FKM strap maintains aesthetic coherence with contemporary personality.

Strap replacement requires access to the spring bars—the spring lever securing the strap to the lugs. Using a dedicated two-pin tool or a small knife, gently compress the spring and extract the pins from the lugs. The old strap loosens automatically. To fit the new 20mm strap, insert the pins into the lugs following the reverse procedure. It is advisable to perform the operation on a soft surface to avoid scratches.

Absolutely. Provided the strap is 20 millimetres wide, any quality aftermarket strap is compatible with the IW3563-10. Choosing artisanal brands using premium leather—alligator, shell cordovan, vegetable-tanned calf—does not compromise the watch's value; rather, it amplifies the wearing experience and enables customisation impossible with factory straps.

Durability depends on leather quality and usage. An alligator or shell cordovan strap of excellent manufacture lasts 5–8 years with moderate daily use. Vegetable-tanned calf, more delicate, resists 3–5 years. Longevity increases significantly if you rotate multiple straps—a practice recommended for valuable watches. Proper maintenance—avoiding prolonged moisture, periodic cleaning, treating with natural balms—extends lifespan considerably. Casati Milano provides an 18-month guarantee on bespoke straps.
