Strap for La Grande Classique 34 Automatic Stainless Steel

The lug width of the Longines La Grande Classique L4.708.4.11.6 is 18mm. This measurement represents the distance between the horizontal axis holes where the strap attaches to the case. It is essential to measure this accurately with a digital calliper, perpendicular to the case, to ensure strap compatibility.

For the L4.708.4.11.6, we recommend a finished alligator for formal contexts, which emphasises the classical elegance of the case, or vegetable-tanned calf leather for those who appreciate natural patina over time. Alternatively, shell cordovan offers robustness and longevity, whilst cotton NATO or FKM rubber give the watch a more sporty-casual character.

To change the strap, you will need a small removal tool (spring bar tool). Position the watch on a soft surface, insert the tool into the small hole under the left lug, gently push inward to compress the internal spring, extract the pin and repeat on the right lug. Insert the new strap by aligning the holes to the lugs and ensuring the pin clicks securely into place.

Yes, on milanostraps.it you can select from dozens of artisanal 18mm straps, crafted in Italy with premium leathers (alligator, calf, shell cordovan) and customisable in sizes, initials and stitching thread colour. All are compatible with your L4.708.4.11.6 lugs and are ready for shipment.

Durability depends on material and usage. Vegetable-tanned calf leather lasts 3-5 years with daily wear, ageing nobly. A finished alligator lasts 4-6 years. Shell cordovan is the most robust (5-7 years). Factors such as exposure to sweat, water and sunlight accelerate wear. An atelier like Casati Milano can regenerate or replace the strap whilst maintaining artisanal quality.
