Strap for La Grande Classique 34 Automatic Yellow

The Longines La Grande Classique L4.708.2.31.2 features a lug width of 18 mm. This is a classical standard that has become relatively scarce in contemporary watchmaking and requires specialised strap suppliers. Accurate lug width measurement is essential to ensure compatibility with aftermarket straps.

For this La Grande Classique, the ideal strap is alligator leather with vegetable tanning in dark brown or cognac colour. This choice respects the proportions of the 34 mm case and creates aesthetic balance with the stainless steel case. An equally balanced alternative is smooth calf leather, which develops a natural patina and maintains the design's simplicity.

The strap on the Longines L4.708.2.31.2 is changed by removing the spring bars that attach it to the lugs. Using a specialised tool or thin screwdriver, lightly press the spring bar whilst withdrawing the strap. It is advisable to consult a qualified watchmaker to avoid damage to the case or movement.

Yes. Aftermarket 18 mm straps are fully compatible with the L4.708.2.31.2 model, provided the lug width is exactly 18 mm. Specialised suppliers such as MilanoStraps offer straps in customisable leather and fabric, with the option of premium leather selections and dedicated finishes.

A quality leather strap (alligator or vegetable-tanned calf) lasts on average 3-5 years with moderate daily wear, developing a natural patina that enhances its character. Durability depends on care, sun exposure and frequency of use. Fabric NATO or FKM rubber straps exceed a decade without significant degradation.
