Strap for Prestige Gold 22.5 Triple Row

The lug width of the Longines Les Grandes Classiques L4.226.7.18.2 is 18 millimetres. This measurement is taken internally between the two lugs of the case and represents the standard dimension for straps compatible with this model. It is essential to verify this measurement before purchasing an aftermarket strap to avoid excessive play or incompatibility.

For this white gold model, alligator leather remains the most authoritative choice: its natural texture and the patina it develops over time amplify the sense of discreet luxury. Shell cordovan is ideal for those desiring a more robust character and extraordinary patina development. Vegetable-tanned calf leather offers an intelligent compromise between elegance and daily practicality. Quality rubber straps are also valid options for those prioritising functionality.

To change the strap, you must remove the spring bars that connect the strap to the case lugs. Using a dedicated spring bar tool, apply gentle pressure to disengage the pin and extract it. Repeat from the other side. To install the new strap, align the slots with the lugs and reinsert the spring bars until they click into place. If you are inexperienced, consult a professional watchmaker.

The lifespan of a leather strap depends on the type of leather and wear. High-quality alligator can last 5-7 years with regular use and proper maintenance. Shell cordovan, thanks to its natural robustness, tends to last longer. Vegetable-tanned calf leather typically has a useful life of 3-5 years. Regular maintenance—gentle cleaning and occasional conditioning—significantly extends the lifespan of any leather strap.
