Strap for Lyre 35 Automatic Stainless Steel

The Longines Lyre L4.860.4.72.6 features a lug width of 18 millimetres. This measurement is standard for classic timepieces in the Lyre family and must be measured perpendicular to the two case lugs where the strap attaches. Always verify the measurement before purchasing an aftermarket strap.

The optimal strap for the Longines L4.860.4.72.6 depends on intended use and personal preference. An alligator strap in cognac brown or deep black represents the aristocratic choice, imparting classical elegance to the timepiece. Shell cordovan offers superior durability and natural curvature. For those prioritising sustainability, vegetable-tanned calf combines tactile performance with environmental responsibility. NATO straps appear oversized relative to the 35mm case proportion of this model.

Changing the strap on the Longines L4.860.4.72.6 requires two tools: a spring bar removal tool and a soft work surface. Position the watch face-down, insert the tool's tip into the small aperture beneath the lug to release the retention spring, then slide the strap outward. Insert the new 18mm strap, verify that the springs engage properly, and confirm the strap aligns symmetrically with the case.

Yes, the Longines Lyre L4.860.4.72.6 is fully compatible with aftermarket straps featuring an 18-millimetre lug width. It is essential to verify that the new strap's terminals fit correctly into the case lugs and that the spring bars are proportionally matched. A wide selection of purpose-designed 18mm straps is available online for this measurement.

The durability of a leather strap depends upon material quality and usage pattern. A quality alligator strap, worn daily, typically lasts 3–4 years before replacement becomes necessary. Shell cordovan, owing to its dense fibre structure, may endure 4–5 years. Vegetable-tanned calf demonstrates intermediate longevity, approximately 2–3 years with regular wear. Exposure to saltwater, humidity, and sunlight accelerates the natural ageing of leather. Casati Milano provides an 18-month warranty on all bespoke straps crafted to order.
