Strap for Lyre 25 Automatic Yellow

The lug width of the Longines Lyre L4.260.2.11.7 is 13 millimetres, a rare and model-specific dimension found on this feminine timepiece. Lug width is measured as the perpendicular distance between the upper and lower anchor points on the case. This precision is critical to prevent lateral play or excessive compression on the strap.

For the Lyre, we recommend first-grade alligator with tight vertical grain, vegetable-tanned calf in neutral tones, or silk and cotton NATO. Alligator emphasises the minimalist geometry; vegetable-tanned calf creates elegant warm-cool contrast. Shell cordovan in standard thickness is inadvisable, being too visually structured.

To change the strap on a Longines Lyre, remove the spring bar (elastic metal rod) connecting the lug to the case using a dedicated tool or blunt knife. Extract the lug from the old strap, insert the new strap, and remount the spring bar ensuring it is firmly seated in both lug holes.

A vegetable-tanned leather strap typically lasts 3–5 years with routine maintenance (soft cloth cleaning, drying after perspiration, solvent protection). Longevity depends on usage intensity, tanning method (vegetable-tanned more durable than chromium tanning), and exposure to moisture and heat. Milano Straps guarantees 18 months on Casati bespoke straps.
