Strap for Lyre Quartz 38.5mm Two Tone / Champagne

The lug width of the Longines Lyre L4.859.2.32.7 is precisely 20 mm. This measurement represents the distance between the metal pins that connect the case to the strap. It is essential to measure correctly to ensure compatibility: a 19 mm strap would be unstable, whilst a 21 mm strap will not fit properly. When ordering an aftermarket strap, always verify that the specification is exactly 20 mm.

For a dress watch like the Lyre, alligator leather with vegetable tanning represents the noblest solution: the geometric texture of the scales dialogues perfectly with the sobriety of the stainless steel case and develops a patina over time. An excellent alternative is shell cordovan, equine leather that hardens progressively, acquiring amber hues. For daily versatility, vegetable-tanned calf offers fine grain and excellent dye absorption. A cotton-silk NATO provides contemporary aesthetics, whilst vulcanised rubber is ideal for intensive use without aesthetic compromise.

Strap replacement requires a specific tool: the spring bar tool. This small instrument allows you to slightly compress the pins (spring bars) at the case ends, releasing the worn strap. Once removed from the old strap, transfer the pins to the new strap by inserting them through the designated holes at the ends. Compress the pins again with the spring bar tool to secure them to the case lugs. If you lack the tool, professional watchmakers perform this operation in minutes. For custom straps, Casati Milano atelier can mount your original pins onto the new strap.

Absolutely. Aftermarket 20 mm straps are fully compatible with the Longines Lyre L4.859.2.32.7 provided they meet the exact lug width specification. On milanostraps.it you will find a selection of artisanal 20 mm straps available in various materials—alligator, shell cordovan, calf, NATO, rubber—customisable in length, initials and stitching thread. These straps offer superior construction quality to the factory original, featuring carefully selected leathers and refined finishing details.

Longevity depends on material and usage. Alligator or shell cordovan with vegetable tanning, if subjected to normal wear (not intensive daily use), lasts 5-8 years before structural failure at the buckle or extremities. Vegetable-tanned calf has slightly shorter durability, 4-6 years, whilst cotton-silk NATO resists 3-4 years. Vulcanised rubber has longevity similar to calf. Determining factors: sun exposure, perspiration, maintenance (periodic cleaning) and frequency of use. Artisanal straps from Casati Milano, featuring vegetable tanning and point-to-point construction, guarantee a minimum of 18 months even under intensive use conditions, with replacement option if necessary.
