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

The lug width of the Omega 5775.71.56 is 24 millimeters. This unconventional measurement compared to modern standards reflects the construction codes of archival models from the 1950s and 1960s that inspired the Museum Collection. To verify it precisely, measure the space between the inner shoulders of the lugs using a digital caliper.

The ideal strap depends on use and aesthetic preferences. Alligator in cognac or warm brown tones is the most conservative choice, consistent with the Museum's heritage identity. Burgundy shell cordovan offers character and evolved patina. An anthracite gray or navy blue NATO combines sportive versatility with archival fidelity. Vulcanized rubber guarantees resistance and functional authenticity. All must feature a 24mm lug width for compatibility.

Position the watch so the lugs face you. Locate the attachment pins (small metal shafts) that pass through the lugs. Using a watch spring bar removal tool, push the pin inward to release it, then remove the old strap. Align the new 24mm strap to the lugs and reinsert the pin until it clicks into place. If you are inexperienced, consult a professional watchmaker.

Yes, 24mm aftermarket straps are available from specialized suppliers of artisanal quality. MilanoStraps offers a collection dedicated to <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-24mm">24mm straps</a>, customizable for size, initials, and stitching color. Always verify that the strap is produced with double attachment (spring bars) to ensure compatibility and secure fastening.

The lifespan of a leather strap depends on material quality, tanning method, and use. A watchmaker-grade alligator with vegetable tanning maintains structural integrity for 4–6 years with daily wear. Shell cordovan, being denser, resists 5–7 years. Calf leather is less robust, approximately 3–4 years. Wear occurs mainly on the buckle and flex area. MilanoStraps straps benefit from an 18-month warranty and can be repaired at the Casati Milano atelier to extend their useful life.
