Strap for Lyre 25 Stainless Steel / White - Roman

The lug width of the Longines Lyre L4.360.4.11.2 is precisely 13mm. This measurement refers to the distance between the two vertical spring bars that hold the strap onto the case. This non-standard dimension requires careful selection of compatible straps, ruling out universal 14mm or 16mm options. It is essential to measure accurately before purchasing an aftermarket strap to avoid damaging the case attachments.

The optimal strap for the Lyre depends on intended use and aesthetic preference. Alligator leather with fine grain is the classical choice: regular texture and restrained lustre complement the case's minimalist proportions. For character-driven selections, vegetable-tanned calf leather develops natural patina over time. Shell cordovan offers internal brilliance that emerges with wear. For daily rotation, a NATO strap in neutral colours (black, navy blue, grey) maintains versatility. Avoid ostentatious straps or decorative buckles: the Lyre requires silent accomplices, not visual competitors.

To change the strap, use a dedicated spring bar tool (attrezzo per i perni). Position yourself in well-lit conditions and place the watch on a soft cloth to prevent scratches. Insert the flat tip of the tool gently under the spring bar, push inward to release the spring, and slide the strap away. Repeat on the opposite side. To install the new strap, insert one end into the spring bar first, then push the bar into its seat until it clicks into position. We recommend consulting a professional if you lack experience, particularly given the delicate proportions of this case.

Compatible straps for the Lyre L4.360.4.11.2 must feature a 13mm lug width. Milano Straps offers a curated selection of artisanal 13mm straps in various materials: alligator, calf leather, natural leather, and fabric options. All are available for immediate dispatch and customisable in length, colour, and details (initials, stitching thread). Additionally, the Casati Milano atelier creates bespoke straps tailored to your specifications, with personal leather consultations and continuous updates throughout the crafting process.

Leather strap longevity depends on leather quality, frequency of use, and maintenance practices. A premium artisanal strap in alligator or calf leather, worn daily, typically lasts 3-5 years before replacement. Vegetable-tanned leather ages with distinction and develops patina that enhances appeal over time. Humidity, perspiration, and sun exposure accelerate wear. Professional straps carry an 18-month warranty against manufacturing defects. Regular maintenance—gentle cleaning, thorough drying, occasional conditioning—significantly extends strap lifespan.
