Strap for Lyre 25 Automatic Yellow

The lug width of the Longines Lyre L4.260.2.11.8 is 13 millimetres. This dimension is specific to this model and corresponds to the proportions of the 25-millimetre case. The measurement is taken from one lug shoulder to the other, passing through the internal mounting hole. It is essential to verify this measurement before purchasing an aftermarket strap.

For the Longines Lyre L4.260.2.11.8, authentic alligator leather or vegetable-tanned calf leather straps are ideal. Alligator offers a naturally squared grain and a golden patina that develops over time, ensuring understated elegance and longevity of 5–7 years. Vegetable-tanned calf develops an authentic patina that narrates the passage of time. For a more casual approach, robust cotton NATO straps represent a versatile alternative.

To change the strap, you will need specific tools: a fine spring bar tool with lever and a stable work surface. Position the watch with the upper lug facing you, insert the spring bar tool into the side hole of the lug to compress the internal spring, extract the rod ends, then remove the worn strap. Install the new strap by compressing the spring again and inserting the rod into the lug cusps. Verify that the rod is properly seated before repeating the operation on the lower lug.

All artisanal straps with a 13-millimetre lug width are compatible with the Longines Lyre L4.260.2.11.8. The specific 13-millimetre lug width limits the choice to models constructed on this dimension. MilanoStraps offers a curated selection of customisable straps in sizes, leathers (alligator, calf, shell cordovan), colours and stitching details, capable of satisfying every aesthetic and functional preference.

The lifespan of a leather strap depends on material quality and usage intensity. An authentic alligator strap with vegetable tanning guarantees 5–7 years of regular wear with ordinary maintenance (drying after water exposure, annual conditioning). A superior-quality vegetable-tanned calf strap lasts 4–6 years. More delicate leather straps (for example, thin skins or specialist finishes) may have a reduced lifespan of 2–3 years if subjected to constant stress. Natural wear of the lugs and deterioration of the stitching are inevitable factors; the strap should be replaced when structural cracks or stitching failure become evident.
