Strap for La Grande Classique Quartz 24 Diamond Bezel

The lug width of this model is 13mm, a non-standard dimension that requires straps constructed specifically for this width. To verify correctly, measure the internal distance between the two lugs at the case attachment point using a digital calliper or ruler. It is not compatible with standard 12mm or 14mm straps.

Your choice depends on intended use: alligator leather with regular grain highlights the minimalist purity of the dial, ideal for formal occasions. Vegetable-tanned calf develops a natural patina over time, perfect for those who appreciate artisanal authenticity. High-density technical rubber ensures daily versatility, while heavyweight NATO canvas completes elegance with discretion. We recommend choosing based on your wardrobe and personal style.

Obtain a spring bar removal tool or consult a watchmaker. Position the watch face-down on a soft cloth, locate the two elastic pins holding the strap, and using the tool insert the flat tip under the pin to release tension, then remove the old strap. Repeat on the opposite side. Insert the new 13mm strap in the same manner, ensuring the pins close firmly in place.

Yes, absolutely. Aftermarket straps of quality construction made for the 13mm lug width are fully compatible with this Longines model. Choose noble leathers (alligator, calf, shell cordovan) from specialised artisans like Casati Milano, where you'll find custom straps with personal selection of materials, finishes and stitching according to your aesthetic preferences.

A premium leather strap has an average lifespan of 5-7 years with daily wear, depending on leather type and care. Materials such as alligator and shell cordovan, thanks to their superior fibre density, maintain structural integrity longer. Vegetable-tanned leather develops natural patina over time, increasing aesthetic appeal. Casati Milano's 18-month warranty covers construction defects, whilst natural wear is part of an authentic strap's beauty.
