Strap for La Grande Classique Automatic 36 Stainless Steel / Yellow Gold PVD / White

The lug width is 18mm. This is the standard width for Longines 36mm cases and provides access to a comprehensive range of compatible artisanal straps. To verify the measurement on an existing timepiece, use a digital calliper, measuring perpendicularly across the case body from the inner point of one lug to the inner point of the other.

The choice depends on your intended use. For formal occasions, a natural satin-finished alligator or vegetable-tanned calf leather ensures enduring elegance. For daily wear, a robust chrome-tanned calf with stainless steel deployante offers practicality without compromising design. If you seek versatility, an aged cognac-coloured calf is wearable both by day and evening.

Position the watch on a soft surface with the case back facing upward. Using a spring bar tool, gently depress the internal spring whilst extracting the metal lug pin. Repeat for the opposite lug. Verify that the pins are correctly aligned with the new strap's holes before reinsertion. If you lack experience, consult a professional watchmaker.

Yes, entirely compatible. The 18mm lug width is universal and permits the installation of any artisanal strap of equivalent width. Quality aftermarket straps frequently offer superior finishes and materials compared to OEM options, and can be personalised in dimensions, colour, stitching and initials.

A strap crafted from superior-quality leather, subject to vegetable tanning, typically endures 3 to 5 years under moderate use with proper maintenance. Longevity depends on daily wear, water exposure, perspiration and storage conditions. An alligator or shell cordovan strap, if adequately protected, can exceed 7 to 8 years. The patina that develops over time is integral to the beauty of natural leather.
