Strap for La Grande Classique Quartz 24 Diamond Bezel

The lug width of the Longines La Grande Classique L4.241.0.12.2 is 13mm. This measurement is essential for strap compatibility and cannot be interchanged with other dimensions. Verifying it with millimetre precision ensures a perfect fit to the case.

For the Grande Classique L4.241.0.12.2, the most suitable materials are alligator—offering a natural and aristocratic texture—and vegetable-tanned calf leather, which develops an elegant patina over time. Both materials respect the understatement of the timepiece without compromise. NATO silk or FKM rubber options are also available for a more contemporary approach.

The strap is changed using a spring bar tool (the small metal pins that fix the strap to the lugs). Insert the tool into the lower hole of the case, gently push inward to release the pin, then remove the old strap and insert the new one. Proceed with caution to avoid scratching the case. If uncertain, have it done professionally at Casati Milano.

No, not all generic 13mm straps guarantee aesthetic and mechanical compatibility. The L4.241.0.12.2 requires straps specifically designed for dress watches with a slim profile and proportionate lugs. Milano Straps' 13mm straps are tested to ensure a flawless fit without friction or movement on the case lugs.

A quality alligator or vegetable-tanned calf strap typically lasts 3-5 years with daily use, developing a patina that enhances its character. Durability depends on humidity, perspiration, and sun exposure. Milano Straps leather straps include an 18-month warranty against manufacturing defects.
