Strap for Lyre 25 Automatic Stainless Steel

The lug width of the Longines Lyre L4.260.4.11.2 is 13 millimetres. This dimension represents the internal distance between the case lugs and must be measured precisely to ensure correct compatibility with any aftermarket strap. Do not confuse this measurement with the case diameter (25mm): the lug width is the physical space where the strap inserts.

For this 25mm ladies' timepiece, the most suitable materials are: alligator (regular texture that dialogues with the clean case lines), vegetable-tanned calf leather (versatile and develops character patina over time), shell cordovan (density and subtle lustre), and FKM rubber for sport versions. The choice depends on usage: formal occasions require fine leather, daily wear allows more robust materials such as NATO or rubber.

The Longines Lyre uses removable bayonet or spring bar attachments. To remove the old strap, use a spring bar tool to gently compress the metal pin and release it from its seats. Position the new strap and reinsert the spring bar into both seats, ensuring it is fully locked. For straps with a tailored passante, verify the length is correct before purchase.

Yes, absolutely. Any strap manufactured with a 13mm lug width is compatible with the Longines L4.260.4.11.2. Milano Straps' artisanal straps are made with this precise dimension and offer construction quality superior to OEM straps, with customisation options in leather, colour, initials, and buckle or deployante type.

Strap durability depends on material and usage. Alligator and shell cordovan with vegetable tanning last 3–5 years with regular daily use, developing rich patina over time. Vegetable-tanned calf leather has similar durability but more visible patination. Milano Straps' artisanal straps include an 18-month warranty and are constructed with hand-stitching that maintains structural integrity over time. Factors such as humidity, perspiration, and UV exposure influence leather longevity.
