Strap for La Grande Classique Automatic 36 Stainless Steel / White

The lug width of the Longines La Grande Classique L4.898.4.11.6 is 18mm. This measurement indicates the internal space between the two lugs of the case where the strap is housed. An 18mm strap sits perfectly without forcing, ensuring a harmonious transition between the case and the wrist.

For this elegant and minimalist timepiece, alligator is the most refined choice: its natural scute texture creates visual contrast with the sober dial. Black or navy blue alligator amplifies the formal character. Vegetable-tanned calf is a sophisticated and more casual alternative, developing patina over time. Shell cordovan offers a lustrous and vibrant surface, ideal for evening occasions.

To change the strap, you must remove the spring bars that fasten the strap to the lugs. Use a spring bar tool to compress the internal spring and slide the pin out from one side of the case. Repeat for the other side. Insert the new 18mm strap, aligning it with the lugs, then reinsert the pins until you feel the locking click. Verify that both pins are correctly positioned.

Yes, any strap with an 18mm lug width is compatible with the L4.898.4.11.6. Aftermarket straps of quality equivalent to the original ensure compatibility and allow greater aesthetic customisation. However, it is advisable to choose straps made by specialist craftsmen to ensure excellent finishing and durability over time.

A quality leather strap lasts an average of 3-5 years with daily use, depending on the material chosen. Alligator and shell cordovan have superior longevity (up to 7-8 years) thanks to the density of the leather. Vegetable-tanned calf tends to wear more quickly but develops a fascinating patina. Durability increases significantly with proper maintenance: avoid prolonged exposure to water and humidity, and store in a cool, dry place.
