Strap for Elegant Collection 25.5 Automatic Stainless Steel / Red Gold / Silver

The Longines Elegant L4.309.5.77.7 features a 13mm lug width, measured between the inner shoulders of the stainless steel lugs. This dimension is specific to the proportions of the 25.50mm case and is narrower than standard watch models. To verify with precision, use a digital calliper positioned perpendicular to the lug shoulders.

We recommend black alligator for pure formality, burgundy shell cordovan for narrative elegance with natural ageing patina, or vegetable-tanned calf leather for daily practicality. The choice depends on dial colour and intended use context. All straps must feature a 13mm lug width.

Strap replacement is performed via spring bars located laterally at the lugs. Use a dedicated tool to gently push the spring inward, releasing the strap from the lug shoulder. Insert the new strap by aligning the holes with the shoulders and release the spring. Avoid excessive pressure on the case to prevent steel scratching.

Yes, provided it is compatible with the 13mm lug width. Artisanal aftermarket straps (leather, cordovan, NATO) integrate seamlessly with the Longines Elegant L4.309.5.77.7, allowing you to personalise the look without construction compromises. Always verify the lug width before purchase.

A quality leather strap (alligator, cordovan, vegetable-tanned calf) on a daily-worn Longines typically lasts 3–4 years, with peaks reaching 5 years if maintained regularly. The leather develops a natural patina, increasing character. Protect from prolonged moisture exposure and condition annually with specific creams.
