To change the strap on the Portofino IW3533-02, use a spring bar tool to compress the lug pins located at the case ends. Once the pins are depressed, the old strap releases. Align the new strap lugs with the pins and press until you hear a click. Specialised ateliers offer this service to minimise the risk of case scratching.

A quality leather strap, properly used and maintained with occasional cleaning, has a lifespan of 3-5 years under daily wear. Vegetable-tanned leather develops a patina that improves its appearance, whilst continuous stress from moisture, dirt, and flexing accelerates ageing. A skilled atelier can replace worn components, extending the strap's service life.
