Strap for La Grande Classique Automatic 36 Two Tone / Champagne

The lug width of the Longines La Grande Classique L4.908.2.31.7 is 20 millimetres. This dimension is standard across all versions of this reference and allows you to select any strap fitted with 20mm spring bars, ensuring universal compatibility without requiring any modifications.

For the La Grande Classique L4.908.2.31.7, the ideal strap is vegetable-tanned alligator in dark brown: the natural grain of the leather reflects the classical aesthetic of the watch, and artisanal finishing amplifies the construction quality. Excellent alternatives include shell cordovan for those who appreciate the natural ageing of leather, or calf for a more uniform and formal appearance.

Changing the strap on the L4.908.2.31.7 is achieved by removing the spring bars using a spring bar tool: position the tool in the groove of the spring underneath the bar, gently push to compress the internal spring, then extract the bar. Repeat on the opposite side. Insert the new strap's bars in the same manner, ensuring the spring clicks correctly into position.

Yes, any strap fitted with standard 20mm spring bars is compatible with the L4.908.2.31.7. Artisanal leather straps from milanostraps.it are specifically dimensioned for this lug width and deliver construction quality equivalent to the original strap, with customisation options in material, colour and stitching.

The lifespan of a leather strap depends on material and usage: an alligator or shell cordovan strap lasts approximately 3–4 years with moderate daily wear; calf has similar longevity in formal environments. Wear concentrates on the buckle and keeper loop. To extend strap life, rotate with other straps and protect from excessive moisture and prolonged direct sunlight.
