Strap for Portugieser Annual Calendar Stainless Steel / Blue

The lug width (ansa) of the IW5035-02 measures 22mm. This dimension represents the internal distance between the two spring bars at the extremities of the dial. It is essential to verify this measurement personally using calliper-grade precision, as 22mm is not a universal specification and requires straps specifically designed for this lug width category.

For the Portugieser, we recommend a polished alligator in black or medium brown, which emphasises the urban elegance of the stainless steel case. Alternatively, shell cordovan allows a natural patina to develop over time, creating aesthetic synergy with the case. For daily use, vegetable-tanned calf leather or a NATO textile strap offer versatility without compromising the authority of the timepiece.

The strap is replaced by removing the spring bars at the dial extremities. Equip yourself with a dedicated spring bar tool to press inward and release the bars, then extract the old strap. Subsequently, align the new strap and reinsert the spring bars until the locking click is felt. If inexperienced, we recommend entrusting this operation to a professional watchmaker or the Casati Milano atelier.

Yes, provided the strap is certified for 22mm lug width. Our artisanal straps are manufactured with metric precision tolerances and are fully compatible with the IW5035-02. We also offer personalisation in dimensions, colours, and details such as hand-engraved initials, ensuring perfect adaptation to your aesthetic preferences.

A high-quality leather strap, manufactured in alligator, cordovan, or vegetable-tanned calf, typically lasts 4-6 years with regular daily wear, depending on factors such as frequency of use, humidity exposure, and maintenance. Casati Milano straps benefit from an 18-month warranty and can undergo periodic maintenance and restoration to extend their operational lifespan.
