Strap for Lyre 25 Quartz Stainless Steel

The lug width of the Longines Lyre L4.259.4.11.6 is 13 millimetres. This measurement represents the distance between the inner lugs of the case where the strap is attached. It is a rare dimension in contemporary watchmaking, requiring a considered approach to sourcing compatible quality straps.

Alligator is the most harmonious material choice for the Lyre's vintage and refined aesthetic, offering natural grain and developing a distinctive patina over time. Excellent alternatives include vegetable-tanned leather calf for daily refined wear, shell cordovan for special occasions, or quality canvas NATO for a considered sports approach.

The strap is changed using a spring bar removal tool. Carefully remove the metal spring bar fastening the strap to the case lugs, extract the old strap, and insert the new one, ensuring the spring bar clicks securely into both lug holes. If uncertain, consult a specialist atelier such as Casati Milano.
