Strap for La Grande Classique 34 Automatic Yellow

The lug width of the Longines La Grande Classique L4.708.2.32.7 is 18 millimetres. This measurement represents the distance between the two strap attachment points on the case and is essential to ensure complete compatibility with your replacement strap.

For a formal timepiece such as La Grande Classique, the finest pairing is with an alligator or ribbed calf leather strap of premium quality. Alligator with its regular grain maintains formal austerity, whilst calf offers a more discreet texture. In vegetable tannage, these materials develop a natural patina that enriches the aesthetics over time. For those seeking a contemporary sporting approach, a quality NATO strap with a deployant clasp represents an excellent alternative.

To change the strap, use a dedicated strap removal tool (spring bar tool). Insert the pointed end into the small slot found beneath the lug on the case, pushing gently upward to release the small elastic pin (spring bar). Once released, the strap detaches easily. To install the new strap, insert the spring bar into the attachment points in sequence and ensure it is securely locked on both sides.

Any strap with an 18-millimetre lug width is compatible with the L4.708.2.32.7 model. Milano Straps offers a comprehensive selection of 18mm straps in alligator, calf, Shell Cordovan and fabric, customisable in final measurement, colour, initials and stitching type, available both online and bespoke at Casati Milano atelier.

The lifespan of a leather strap depends on material quality, frequency of use and care. A first-quality alligator or calf strap with vegetable tannage maintains functionality and aesthetics for 4–8 years of daily wear. Factors such as humidity, direct sunlight exposure and wrist perspiration accelerate the natural ageing of leather. Milano Straps provides an 18-month guarantee on straps crafted bespoke at Casati Milano atelier.
