Strap for Lyre Quartz 38.5mm PVD Gold / Champagne

The Longines Lyre L4.859.2.32.2 features a lug width of 20 mm. This dimension, now rare in contemporary production, represents one of the most distinctive characteristics of this model and requires careful selection of compatible aftermarket straps. To verify the width, measure the distance between the two spring bar holes on the case.

An alligator strap with fine grain and vegetable tanning is the ideal choice for this model: the regular texture of the leather dialogues perfectly with the classical construction of the stainless steel case. Alternatively, fine grain calf leather offers superior comfort, whilst shell cordovan introduces structural density that evolves over time. For sporting contexts, rubber or textile NATO straps are acceptable options.

The strap is changed by removing the lateral spring bars (the small metal pins that traverse the lugs). Use a spring bar tool, a specialised instrument with a forked end, to compress the internal spring and slide the pin out. Insert the new strap by aligning the holes with the bars, and push until the locking click. Avoid using improvised tools as they may damage the case.

Yes, aftermarket straps of 20 mm width are specifically manufactured for this lug size. On milanostraps.it you will find a selection of artisanal 20mm leather straps customisable in leather type, size, initials and stitching thread. Atelier Casati Milano also offers bespoke straps created to measure with conscious leather selection and an 18-month warranty.

A quality natural leather strap (alligator, calf, shell cordovan) typically lasts 2-4 years with daily use and proper maintenance. Longevity depends on environmental humidity, frequency of use, and the care applied. Regular maintenance—drying after water exposure, application of specific balms, storage in a dry environment—significantly extends the life of the strap. Vegetable tanning ensures a patina that evolves over time, offering natural protection against wear.
