Strap for Lyre 35 Automatic Yellow

The lug width of the Longines Lyre L4.760.2.11.2 is 18 millimetres. This measurement, specified in the official Longines documentation, represents the distance between the two holes where the spring bars pass through to secure the strap. Accurate measurement of lug width is essential when selecting aftermarket straps: using a digital calliper positioned on the outer poles of the holes ensures maximum precision and guarantees proper fit.

For a dress watch such as the Longines Lyre L4.760.2.11.2, an alligator leather strap represents the optimal choice: the natural texture and characteristic longitudinal grains of the reptile skin complement perfectly the minimalist lines of the case. Recommended colours include medium brown (cognac), deep black, or graphite grey. Alternatively, vegetable-tanned calf leather offers a unique patina development over time, ideal for those who appreciate the chromatic evolution of leather.

To change the strap, you must remove the spring bars that pass through the lugs. Using a spring bar tool (a specialised implement with a dual-ended tip), position one end into the small hole located beneath the lug to compress the internal spring mechanism, then extract the spring bar laterally. Repeat for the opposite side. Align the new strap's holes with the lugs and reinsert the spring bars until they click into place. If you lack experience, consult a professional watchmaker.

Yes, absolutely. The Longines Lyre L4.760.2.11.2 with 18mm lugs is compatible with any strap manufactured for this lug width. Aftermarket straps offer significant advantages over the original: complete personalisation regarding material, colour, thickness, and closure type (standard, deployante, or bespoke buckle). Always verify that the strap is specifically constructed for 18mm lug width to ensure proper fit.

Leather strap longevity depends on usage frequency, climatic conditions, tanning method, and maintenance. An alligator strap in vegetable tanning, worn daily on a dress watch such as the Lyre, maintains structural integrity and flexibility for 3-5 years. The leather develops increasingly rich patina during the first year, then ageing slows considerably. Prolonged humidity exposure reduces lifespan; conversely, regular maintenance (gentle cleaning, conditioning treatments) significantly extends it.
