Strap for Museum Collection N° 1 "Pilots 1938" Aquarella Black Diamonds

The lug width is 24 millimeters. It is measured as the distance between the two lugs (the axes that connect the case to the strap). This dimension reflects the standards of instrument watches from the 1950s and 1960s, and is a rare feature in contemporary models that requires careful selection of artisanal straps.

The ideal strap depends on the intended use. For formal contexts, we recommend vegetable-tanned calf leather in dark brown tones or shell cordovan. For a more sporty aesthetic, a cognac alligator strap or cream linen technical fabric maintains the historical coherence of the model. Rubber straps are not recommended, as they would contrast with the refined design.

To change the strap, you need to remove the lugs (the axes) using a dedicated tool (spring bar tool). Position the watch on a stable support, locate the lugs at the ends of the case, and extract them gently. Insert the new strap by aligning the lugs with the holes, then reinsert the pins. If you lack experience, entrust the task to a specialized artisan such as Casati Milano, who will proceed with precision.

Alligator with vegetable or chromium tanning offers natural elasticity and a patina that evolves over time. Superior quality calf leather ensures sobriety and durability. Shell cordovan represents the ultimate choice for longevity and extraordinary aging. Linen or quality canvas fabric maintains the historical aesthetic lightness of the watch. All these materials are available in the 24mm size from specialized artisans.

Durability depends on the quality of the leather and use. A strap in quality alligator or artisanal calf leather typically lasts 3-5 years with regular maintenance. Shell cordovan can exceed 7-10 years, developing a fascinating patina. A good warranty (such as the 18 months offered by Casati Milano) covers manufacturing defects. Longevity increases by avoiding prolonged exposure to humidity and perspiration.
