Strap for Lyre 25 Automatic Yellow

The lug width of the Longines Lyre L4.260.2.12.2 is precisely 13mm. This measurement represents the internal distance between the two lugs of the case and is the decisive parameter for selecting a compatible strap. To measure it correctly, use a flexible metal ruler, positioning the internal zero on the upper lug and measuring to the internal zero of the lower lug.

For the Longines Lyre L4.260.2.12.2, a black or brown alligator strap represents the most refined choice, coherent with the watch's aesthetic identity. Cognac shell cordovan is excellent for champagne dials, whilst grey pearl vegetable-tanned calf offers a modern and sustainable balance. Navy NATO and rubber straps are ideal for daily wear and sports use.

Changing the strap on the Longines Lyre L4.260.2.12.2 requires the use of a spring bar tool. Position the watch on a stable surface, insert the flat end of the tool into the groove of the upper lug to compress the internal spring, extract the lug from one side, remove the strap, then position the new strap and reinsert the lug. Repeat the operation for the lower lug. If you prefer, the Casati Milano atelier performs the change by appointment.

Yes, it is possible to use an aftermarket strap provided the lug width is exactly 13mm.

Additionally, it offers customisation in sizes, initials and stitching thread choice, and the bespoke service of Casati Milano creates custom straps with leather of your personal choice.

The lifespan of a leather strap depends on the material and usage. A high-quality artisanal alligator or shell cordovan strap typically lasts 3-5 years of regular wear, with a patina that deepens over time and becomes part of the watch's history. Calf leather is slightly less durable (2-4 years). The 18-month warranty offered by Casati Milano covers manufacturing defects, but with proper care (avoiding prolonged moisture, protecting from excessive sweat, periodic hydration), longevity extends considerably.
