Strap for Lyre Quartz 38.5mm Two Tone / Roman

The lug width of the Longines Lyre L4.859.2.11.7 is 20 mm. This measurement corresponds to the distance between the two attachment points of the case and is essential when purchasing a compatible strap. We recommend measuring with a digital calliper between the internal lugs, excluding external case protrusions, to obtain the most accurate measurement.

For the Longines Lyre L4.859.2.11.7, we recommend an alligator strap with vegetable tanning for maximum elegance, or shell cordovan for durability and character. Mass-dyed calf leather represents a balanced choice between versatility and refinement. For controlled sporting use, natural rubber or a NATO strap ensures water resistance and practicality.

Changing the strap on a Longines Lyre L4.859.2.11.7 is accomplished by removing the spring bars (small metal pins) that attach the strap to the case lugs. We recommend using a dedicated spring bar tool or consulting a professional watchmaking workshop. The operation is straightforward if executed carefully: place a cloth under the case to prevent scratches, compress the spring bar's tension and slide it out of the lug, then insert the new strap and resecure the spring bar.

Any strap manufactured with a 20 mm lug width is compatible with the Longines Lyre L4.859.2.11.7, provided it meets strict construction tolerances (±0.5 mm). We recommend straps made by specialist artisans who guarantee precision in fitting and material quality. Avoid generic, low-quality straps: the Lyre deserves a bespoke solution.

A high-quality leather strap (alligator, shell cordovan, or premium calf) worn with controlled use typically lasts 3-5 years before requiring replacement due to natural wear. Vegetable-tanned leather develops a patina that improves its appearance over time. With proper maintenance (avoid prolonged water exposure, dry after accidental water contact, store in a dry environment), lifespan can extend to 6-7 years. Rubber straps, conversely, guarantee superior longevity (7-10 years) but with less refined aesthetic character.
