Strap for Lyre 25 Automatic Stainless Steel

The lug width of the Longines Lyre L4.260.4.12.2 is 13mm. This specific measurement determines compatibility with aftermarket straps. To measure a lug width accurately, insert a digital calliper into the centre of the lug attachment, from shoulder to shoulder. On milanostraps.it, you will find a complete selection of straps specifically manufactured for this 13mm width.

The best strap depends on your dial colour and intended usage. For a dress watch of this calibre, we recommend alligator in brown or black tones, or European calf leather with vegetable tanning. If your dial is silver, a cognac-brown strap is universally appropriate. If your dial is blue, opt for black or navy blue. For versatility, consider owning at least two straps in complementary colours.

To change the strap, position your watch with the lugs facing upwards. Use a dedicated spring bar tool to gently push the elastic pin of the lower lug, thereby freeing the strap from the case. Repeat on the opposite side. Insert the new strap by aligning the holes and press until you hear the spring click into place. The operation takes less than two minutes if you have the correct tool.

Yes, the Longines Lyre L4.260.4.12.2 is fully compatible with quality aftermarket straps. The 13mm lug width is a standard measurement that allows installation of straps in leather, fabric or technical rubber from specialised suppliers such as milanostraps.it. Ensure that your strap is manufactured specifically for 13mm width to guarantee a perfect and stable fit.

The lifespan of a leather strap depends on material quality and usage patterns. A high-quality alligator or shell cordovan strap with vegetable tanning can last 3-5 years with moderate daily wear. Standard European calf lasts 2-3 years. To extend longevity, avoid prolonged exposure to moisture and direct sunlight, clean periodically with a soft cloth, and occasionally apply a natural leather conditioner. Straps crafted by Casati Milano include an 18-month guarantee.
