Strap for Lyre 25 Automatic Yellow

The lug width of the Longines Lyre L4.260.2.12.8 is 13mm. This measurement is specific to this model and does not represent a widely available standard in the aftermarket strap market. To verify it, measure the distance between the two pins that support the strap using a digital calliper, measuring from centre to centre. Precise compatibility is essential to avoid visible gaps at the sides of the case or risks of damage during strap insertion.

For the Lyre L4.260.2.12.8, we recommend alligator straps for classic elegance with pronounced texture, or shell cordovan for those desiring a patina that evolves over time. Vegetable-tanned calf leather is ideal for aesthetic minimalism and softness to the touch. Your choice depends on usage context and dial colour: dark brown or burgundy alligator for silver dials, hazelnut calf for warm tones. All straps must have a 13mm lug width to ensure structural compatibility.

Changing the strap on the Longines Lyre L4.260.2.12.8 requires the use of a spring bar tool or a specific replacement kit. Position the watch with the case facing upwards, locate the pins supporting the strap (one on each side), then insert the tool into the small hole next to the pin and lift gently. The pin will snap out of its seat. Remove the old strap, align the new strap (13mm) and reinsert the pins into their seats. Ensure the pin is fully locked before wearing the watch. If unsure, consult a professional watchmaker.

Yes, quality aftermarket straps are fully compatible with the Longines Lyre L4.260.2.12.8, provided they strictly respect the 13mm lug width. Not all manufacturers offer this specific measurement, so the search requires attention. Bespoke handcrafted straps, such as those created by Casati Milano, guarantee millimetre precision and can be personalised in leather type, colour, thickness and stitching thread, adapting perfectly to your aesthetic preferences and wrist movements.

The lifespan of a leather strap depends on the quality of craftsmanship, the type of leather and usage patterns. A well-made alligator or shell cordovan strap typically lasts 2–4 years with moderate daily use. Vegetable-tanned calf, being softer, may remain functional for 18–36 months. Longevity increases significantly if you rotate straps, avoiding continuous use of the same one. Bespoke straps with an 18-month warranty offer protection against manufacturing defects. Regular strap changes also preserve the overall aesthetic value of the watch, as a worn strap compromises the Lyre's elegance.
