Strap for Lyre 35 Automatic Stainless Steel

The lug width of the Longines Lyre L4.760.4.12.6 is 18.00mm. This is a critical specification: most standard straps are available in 20mm, a size that creates visual disproportionality on this model. To verify the measurement, position a digital calliper between the lugs (the metal axles that attach the strap). The 18mm width maintains the classical harmony of the 35mm compact case.

For the Lyre, we recommend vegetable-tanned leather of medium thickness (1.4-1.6mm): calf leather develops a natural patina that ages beautifully, whilst alligator offers a regular texture that dialogues with the dial's purity. Shell cordovan represents a premium alternative for those desiring a leather that hardens and becomes waterproof over time. We advise against rubber or NATO straps: their sporty aesthetic contradicts the piece's sober identity.

Position the watch on a soft surface and with a ballpoint pen (or dedicated tool) press the small retractable button located beneath the case, near the lug. This quick-release system unlocks the pin, allowing you to remove the old strap. Insert the new strap (18mm width) and press the pin until you hear a click. Verify that the strap is securely fastened before wearing the watch.

Yes, absolutely. The standard 18mm lug width is compatible with any artisanal or commercial strap of the same width. We recommend opting for superior construction quality: vegetable-tanned leather, calf, alligator, or shell cordovan. These materials offer greater longevity compared to synthetics and develop a natural patina that synchronises with the steel case's ageing.

Durability depends on material and usage. A vegetable-tanned calf strap, with correct thickness (1.4-1.6mm) and solid buckle, resists 3-5 years of moderate daily wear. Alligator and shell cordovan guarantee 5-7 years. Casati Milano offers an 18-month warranty on artisanal straps, ensuring that any construction failures are covered. Removing the watch at night and protecting it from excessive humidity significantly extends strap life.
