Strap for Lyre 35 Automatic Yellow

The lug width of the Longines Lyre L4.860.2.32.2 is 18 millimetres. This measurement is determined by calculating the exact distance between the two spring bars that connect the strap to the watch lugs. It is a rare and sophisticated dimension, specifically designed to maintain harmonious proportions on a 35mm diameter timepiece.

For the Longines Lyre L4.860.2.32.2, straps in alligator, shell cordovan, or vegetable-tanned calf leather are recommended. Black or cognac alligator offers minimalist elegance; burgundy shell cordovan creates warm contrast; grey-brown calf ensures versatility. For summer wear, NATO straps in neutral tones maintain freshness. The choice depends on intended use and personal colour preferences.

To change the strap on a Longines watch, you must remove the spring bars connecting the strap to the lugs. Using a spring bar tool, insert the tip into the groove beneath the lug, compress the bar, and extract the old strap. Then insert the new strap, ensuring the spring bars click correctly into place. For precious watches such as the Lyre, professional assistance is recommended.

Yes, the Longines Lyre L4.860.2.32.2 is compatible with aftermarket straps featuring 18mm lug width. Standard spring bars allow the use of high-quality bespoke straps. However, as 18mm is a less common size than 16mm or 20mm, commercial availability is limited. We recommend consulting specialised workshops that produce custom straps.

The lifespan of a leather strap depends on the type of leather and usage patterns. High-quality alligator or shell cordovan with vegetable tanning typically lasts 3-5 years with regular wear. Vegetable-tanned calf usually lasts 2-4 years. Humidity, perspiration, and wearing frequency affect ageing. Artisanal straps with specific treatments and quality finishes offer superior durability; Casati Milano, for example, provides an 18-month warranty on bespoke straps.
