Strap for La Grande Classique 34 Automatic Stainless Steel

The lug width (ansa width) of the Longines La Grande Classique L4.708.4.72.6 is 18mm. This measurement represents the distance between the two metal pins where the strap is inserted. Precision measurement using a digital calliper is essential to ensure aftermarket strap compatibility.

The best strap depends on its intended use: alligator leather in cognac brown suits formal and business contexts, whilst calf leather with vegetable tanning offers daily versatility. Shell cordovan in black represents a sophisticated choice for those seeking a natural patina that evolves over time. For the white dial, avoid straps with excessively pronounced grain or saturated colours.

Strap replacement requires a spring bar tool. Insert the small fork into the slot beneath the pin and gently lift until the pin releases from the case lug. Remove the old strap carefully. Consult a professional watchmaker if inexperienced: incorrect pressure may scratch the ultra-thin case.

All straps with an 18mm lug width are compatible. Milanostraps.it offers a complete selection of artisanal leather straps (alligator, calf, shell cordovan) and textile options, customisable in length, colour and stitch thread. The Casati Milano atelier also produces bespoke made-to-measure straps.

Lifespan depends on material and usage. Alligator and shell cordovan guarantee 4-6 years of daily wear; vegetable-tanned calf resists 3-5 years whilst developing a prized patina. Direct sun exposure and excessive humidity reduce longevity. Casati Milano straps carry an 18-month warranty and can be renewed or repaired by the atelier.
