Strap for La Grande Classique Quartz 37 Stainless Steel / White - Eastern Arabic

The lug width of the Longines La Grande Classique L4.766.4.13.2 is precisely 20 millimetres. This measurement is exact and cannot vary: the distance between the two lugs must be exactly 20mm to ensure perfect strap compatibility.

There is no single best choice, as it depends on usage and aesthetic preference. For formal occasions, we recommend vegetable-tanned alligator in brown or black tones. For refined everyday wear, hand-stitched calf leather in charcoal grey or black is ideal. For versatility with natural patina development, shell cordovan is unmatched. Milano Straps offers all these options in bespoke 20mm leather straps.

The process is straightforward: locate the metal lugs on both sides of the case (protruding from the ansa). Using a spring bar tool or small lever, compress each lug inward and slide the old strap away from the case. Insert the new 20mm strap by aligning the holes, then release the lugs. Verify secure attachment before wearing the watch.

Yes, numerous high-quality aftermarket options exist. Milano Straps offers a comprehensive collection of artisanal 20mm straps: vegetable-tanned leather, alligator, shell cordovan, and technical fabrics. Each strap is handcrafted to haute couture standards and guarantees certified compatibility with the 20mm lug width.

A quality artisanal leather strap typically lasts 3-5 years of daily wear, depending on intensity of use and care. Robust leathers such as shell cordovan and alligator tend to last longer. Milano Straps provides 18 months guarantee on straps crafted at the Casati Milano atelier, with options for lug replacement and long-term maintenance.
