Strap for La Grande Classique Automatic 36 Stainless Steel / Yellow Gold PVD / White

The lug width of the Longines La Grande Classique L4.898.3.11.7 is 18 millimetres. This dimension is fixed and defines this model: all compatible straps must measure exactly 18mm in width to fit correctly onto the case's lug attachments.

For the L4.898.3.11.7, alligator straps in black are ideal for formal occasions, or vegetable-tanned calf leather for those seeking natural patina development over time. Smooth calf leather in dark shades (brown, black) ensures understated elegance, whilst woven NATO fabric in tight weaves is perfect for daily wear without sacrificing refinement.

The strap is changed using a spring bar remover: insert the small lever into the hole beneath the lug, gently push upward to release the spring bar, then remove the old strap and insert the new one, aligning it precisely with the case's attachments. The operation requires care to avoid scratching the case.

Yes, absolutely. Aftermarket straps measuring 18mm are fully compatible with the L4.898.3.11.7, provided they are manufactured to correct specifications. milanostraps.it offers a curated selection of 18mm straps personalizable in leather, colour, and stitching, ensuring precise fit to the original attachment.

Lifespan depends on material and use. An alligator or shell cordovan strap, with regular maintenance (avoiding excess moisture and dirt), lasts 3–5 years. Vegetable-tanned calf wears faster (2–3 years) but develops valuable patina. Casati Milano straps include 18 months warranty and may be replaced periodically.
