Strap for La Grande Classique Quartz 23 White Gold

The lug width of the Longines L4.191.7.72.6 is 12mm. This dimension is specific to this model and requires straps manufactured specifically for this measurement. It is not compatible with standard strap widths (14mm, 16mm, 18mm).

Alligator leather with fine grain is the ideal choice, offering aesthetic nobility and superior flexibility. An excellent alternative is vegetable-tanned calf leather, which develops a natural patina over time. For less formal contexts, shell cordovan (if available in 12mm) represents the highest standard in chromatic performance and durability.

Use a spring bar tool (a blunt-pointed instrument) to extract the small metal pins (spring bars) that hold the original strap to the case lugs. Insert the tool under the strap near the lug and gently lift until the spring bar releases. Repeat on the other side. To install the new strap, align the strap holes with the lugs and press the spring bar into position using the tool.

Yes, but only straps specifically manufactured for the 12mm lug width. Do not attempt to use standard straps of different widths, as they may damage the case lugs. Milano Straps offers a comprehensive collection of 12mm straps in various materials (alligator, calf, fabric) ready for shipment and customisable upon request.

The lifespan of a leather strap depends on frequency of wear and material quality. High-quality alligator, worn daily, maintains structural integrity for 5-7 years. Vegetable-tanned calf typically lasts 3-5 years with intense wear. In any case, leather naturally deteriorates and replacement is part of routine maintenance for a luxury timepiece. Milano Straps guarantees its straps for 18 months.
