Strap for Lyre Quartz 38.5mm PVD Gold / Roman

The lug width of the Longines Lyre L4.859.2.11.2 is 20mm. This measurement is determined by calculating the distance between the two pins that attach the strap to the case lugs. A 20mm lug width characterizes the constructive proportion of the Lyre, creating visual harmony between the 38.50mm diameter and the overall case circumference.

For the Lyre L4.859.2.11.2, we recommend straps in alligator, vegetable-tanned calf leather, or shell cordovan. Alligator, with its natural vertical grain and patina that matures over time, respects the dress-oriented aesthetic of this timepiece. Vegetable-tanned calf offers a matrix texture that ages beautifully, whilst shell cordovan is the audacious choice for those seeking intrinsic lustre and deep burgundy tones.

To change the strap, remove the watch from your wrist and place it on a flat surface. Using a dedicated spring bar tool or a small flat object, gently push upward on one of the pins securing the strap to the lug. The pin will retract, allowing you to remove the old strap. Insert the new strap by aligning it with the lug holes and push the pin back into position. Repeat on the opposite side.

The Longines Lyre L4.859.2.11.2 accepts any strap with a 20mm lug width. In the contemporary artisan market you will find straps in alligator, calf leather, shell cordovan, NATO, and rubber—all constructed for 20mm width. Ateliers such as Casati Milano offer custom-made straps personalizable in material, colour, lug thickness, and buckle type (deployante or traditional pin buckle).

A high-quality artisan leather strap (alligator, calf, shell cordovan) lasts 3-5 years in daily use with ordinary maintenance. Lifespan depends on water exposure, perspiration, humidity, and temperature fluctuations. Vegetable-tanned leather tends to resist longer than synthetic-tanned alternatives. With occasional maintenance (gentle cleaning with damp cloth, rapid drying), the strap will age, developing a patina that increases its aesthetic value.
