Strap for Lyre 25 Automatic Yellow

The lug width of the Longines Lyre L4.260.2.32.7 is precisely 13 millimetres. This measurement is fixed and represents the distance between the inner ends of the two suspension pins on the case. Verifying this dimension before purchasing a compatible strap is essential, as even minimal variation would result in poor fit.

For the Longines Lyre L4.260.2.32.7, natural alligator represents the most refined choice, as its orderly grain pattern dialogues perfectly with the minimalist aesthetic of the 25mm case. Smooth or textured calf leather offers versatility, whilst shell cordovan ensures longevity and develops patina over time. A cotton NATO allows a more casual interpretation whilst maintaining elegance.

To change the strap, use a dedicated tool (spring bar tool) to remove the suspension pins from the case ends. Position the tool in the lateral slot of the pin and apply gentle pressure to expand it, extracting it from the case hole. Repeat for the other pin. To install the new strap, align the holes in the leather with the pins and reinsert them using the same tool, ensuring they are securely anchored.

Yes, you can use aftermarket compatible straps provided they strictly respect the 13-millimetre lug width. Milanostraps offers a complete collection of straps in alligator, calf leather, shell cordovan and rubber specifically compatible with this measurement. It is crucial to verify the specific lug width before purchase to avoid incompatibility.

The lifespan of a leather strap depends on the type of leather and usage patterns. An artisanal quality calf leather strap, with moderate wear, lasts approximately 3-5 years before requiring replacement for aesthetic reasons. Shell cordovan, thanks to its density, can exceed 7-10 years whilst developing increasingly deeper patina. Vegetable tanning guarantees superior durability compared to industrial tannage methods. Proper maintenance—avoiding prolonged exposure to excess moisture and heat—significantly extends the strap's useful life.
