Strap for Lyre 40 Automatic PVD Gold / White / Bracelet

The lug width of the Longines Lyre L4.961.2.12.7 is 21mm. This precise measurement is determined by the distance between the two lugs on the case and requires straps specifically manufactured to this specification. It is advisable to measure with a digital calliper from centre to centre of the lug to ensure absolute compatibility.

Alligator is the reference material for the Lyre: its natural grain and patina enhance the minimalist design of the stainless steel case. Shell cordovan is the alternative for those seeking tactile depth and natural luminosity. Vegetable-tanned calf offers chromatic versatility and rich patina. Rubber ensures functionality for sports use, whilst NATO in canvas and leather maintains the watch's serious character.

The strap on the L4.961.2.12.7 is changed by removing the two lugs (the pins that pass through the case) using a dedicated strap removal tool or a small screwdriver. Gently push the pointed end from the opposite side until the pin exits the case shoulder. Subsequently, align the holes of the new strap with the lugs and reinsert the pins. The operation requires care to avoid scratching the case.

Yes, the L4.961.2.12.7 is completely compatible with any quality 21mm strap. It is essential to verify that the lug width is exactly 21mm and that the pins used are of the same configuration as the originals. Bespoke artisanal straps ensure perfect fit and superior durability compared to industrial straps.

A quality leather strap on a watch like the Lyre typically lasts 3–5 years with moderate daily wear, depending on frequency of use, moisture exposure and strap material. Alligator and cordovan age elegantly and may last longer. Vegetable-tanned calf develops a patina that extends its lifespan. Rotating with other straps and periodic maintenance (cleaning, conditioning) significantly prolongs durability.
