Strap for Elegant Collection 25.5 Automatic Stainless Steel / Red Gold / White

The lug width of the Longines Elegant L4.309.5.11.7 is precisely 13mm. This measurement is obtained by measuring the space between the inner lugs of the case at the point where the strap attaches. The 13mm width is calibrated to the case's 25.50mm diameter and is essential to maintain the aesthetic and structural balance of the model.

Genuine alligator leather is the most natural choice for this model, thanks to its regular texture and characteristic grain that reflects the horological craftsmanship of the timepiece. Equally dignified alternatives include fine-grain calf leather in neutral tones and shell cordovan. For a more informal choice, canvas and NATO straps remain practical, though they slightly compromise the aesthetic balance of the delicate case.

Strap replacement requires a specific tool called a 'spring bar remover'. Locate the spring bars at the ends of the lugs: insert the tool into the slot to compress the spring, then extract the spring bar outward. Repeat the operation on the other side. Position the new 13mm strap by aligning the holes with the attachment points, reinsert the spring bars and verify they are securely locked.

Yes, provided the lug width is strictly 13mm. The aftermarket-compatible straps available in the catalogue at Milano Straps have been selected to respect this constructive specification. Always verify that the strap does not present excessive tolerances, as a loose fit could compromise both aesthetics and function.

The lifespan of a leather strap varies depending on the leather quality, frequency of wear and environmental conditions. A high-quality alligator or calf strap with vegetable tanning typically lasts 3-5 years with daily wear, developing an authenticated patina over time. Leather straps require periodic maintenance and protection from excessive moisture. Casati Milano atelier provides straps with an 18-month warranty and support for replacement with freshly stitched thread.
