Strap for Lyre 35 Automatic Yellow

The lug width of the Longines Lyre L4.860.2.11.8 is 18mm. This measurement is critical for strap compatibility and must be measured precisely between the inner edges of the case lugs. Using straps of incorrect width (16mm or 20mm) compromises both aesthetics and functionality.

The optimal strap depends on usage and aesthetic preferences. Alligator leather with vegetable tanning is the most historically coherent choice, offering elegance and longevity. Shell cordovan is excellent for those who appreciate a natural patina that develops with wear. Smooth calf leather provides daily versatility, whilst woven NATO fabric offers a more sporty aesthetic.

To change the strap, use a spring bar tool to remove the lug bars from the case. Apply gentle pressure on the small lever of the spring to disengage it from the case lug. Work on a soft surface to avoid scratches. If you lack experience, consult a professional watchmaker or the Casati Milano atelier for assistance.

Yes, any strap with an 18mm lug width is compatible with the Longines Lyre L4.860.2.11.8. Milanostraps.it offers artisanal 18mm straps specifically curated for this model, customizable in leather, dimensions, and stitching details. The Casati Milano atelier can also craft bespoke straps with your choice of leather.

Longevity depends on material and wear patterns. Alligator and vegetable-tanned shell cordovan typically last 5–8 years with daily wear, developing character over time. Smooth calf leather has similar lifespan but requires more maintenance. Premium straps from Casati Milano carry an 18-month guarantee and can endure over a decade with proper care (gentle cleaning and protection from excessive moisture).
