Strap for La Grande Classique Tonneau 22 Stainless Steel

The lug width of the Longines La Grande Classique L4.205.4.11.6 is 16 millimetres. This measurement represents the distance between the two strap attachment pins on the case and is essential for ensuring structural compatibility. A 16mm strap allows precise fitting without mechanical play, preserving the aesthetic balance of the 22.20mm case.

For the La Grande Classique L4.205.4.11.6, we recommend alligator or vegetable-tanned calf leather. Alligator offers a natural patina that evolves over time, reflecting the concept of graceful ageing that characterises the watch. Calf leather ensures tactile softness and chromatic versatility. For daily wear, cotton NATO in neutral tones (grey, navy) represents a practical alternative that maintains the model's aesthetic sobriety.

Strap replacement is a straightforward operation requiring a dedicated tool (spring bar tool). Insert the flat tip of the tool under the pin, releasing the tension of the internal spring. Once the pin is freed from the outer side, remove the old strap. To install the new one, align the lateral slots with the pins and press until they engage. Always verify that both sides are perfectly secured before wearing the watch.

The lifespan of a leather strap depends on the material and usage. Vegetable-tanned alligator or calf, if maintained with regular cleaning and protection from excessive moisture, typically lasts 5-7 years. Shell cordovan, thanks to its extreme density, can exceed 10 years of wear. Natural leather, if exposed to frequent perspiration or direct rain, ages more rapidly. Casati Milano offers an 18-month guarantee on handcrafted straps and can perform specialised repairs.
