Strap for Lyre 25 Automatic Yellow

The lug width of the Longines Lyre L4.260.2.12.7 is 13mm. This non-standard size was chosen to maintain correct optical proportions on the 25mm case. To verify compatibility, measure the distance between the lugs (the axes on which the strap attaches): it must be exactly 13mm.

The best strap depends on intended use and aesthetic preference. Alligator offers maximum elegance with a fine grain that dialogues perfectly with the 25mm case; vegetable-tanned leather is versatile and develops a beautiful patina over time; shell cordovan represents a long-term investment with deep colour and character. For daily wear, a heavy-duty canvas NATO keeps comfort and protects the primary strap.

Strap replacement is performed by removing the spring bars (small metal axes at the case extremities) using a dedicated spring bar tool. Position the watch on a stable surface, gently remove the bars one at a time, extract the old strap and insert the new one. If unfamiliar with the procedure, consult a watchmaker or the Casati Milano atelier to avoid case damage.

Yes, any strap with a 13mm lug width is compatible with the Longines Lyre L4.260.2.12.7. Milano Straps offers a curated collection of 13mm straps specifically designed for watches with this size, guaranteeing perfect fit and aesthetic coherence with case proportions.

The lifespan of a leather strap varies depending on use and material quality. A quality artisanal alligator or vegetable-tanned leather strap typically lasts 3-5 years with moderate daily wear. Factors such as humidity, sun exposure and frequency of wear influence longevity. The Casati Milano atelier offers an 18-month warranty on all artisanal-made straps.
