Strap for Elegant Collection 25.5 Automatic Stainless Steel / Grey / Strap

The Longines Elegant L4.309.4.72.2 features a lug width of 13mm. This is the width of the attachment point where the strap inserts into the spring bar mechanism of the case. It is essential to order straps specifically designed for this measurement to ensure proper fit and balanced aesthetics.

The optimal strap depends on your intended use. For formal elegance, we recommend alligator with vegetable tanning or shell cordovan, both capable of developing natural patina over time. For daily versatility, vegetable-tanned calf leather offers durability and refined appearance. For sporting environments, FKM rubber ensures water resistance without aesthetic compromise. Milano Straps offers 13mm straps customisable in length, colour, and thread.

The strap is changed using a spring bar removal tool. Gently open the spring bar mechanism from the underside, extract the bar from the old strap, then insert it into the new strap ensuring it clicks firmly into position. If you lack experience, we recommend having an authorised service centre perform this operation to avoid case damage.

Yes, it is possible. Aftermarket 13mm straps are compatible with the Longines Elegant L4.309.4.72.2, provided the lug width is precisely 13mm. Milano Straps creates bespoke artisanal straps with hand-selected leathers and customisable finishes, offering superior quality to standard straps. Each strap is constructed to fit your case proportions perfectly.

Leather strap longevity depends on tanning method, usage frequency, and maintenance. An alligator or shell cordovan strap with vegetable tanning, worn daily, typically lasts 3-5 years before replacement. If worn occasionally, lifespan may extend to 5-7 years. Casati Milano straps include 18-month warranty and can be regenerated or replaced through the personalised maintenance service.
