Strap for Lyre 25 Quartz Stainless Steel

The lug width of the Longines Lyre L4.259.4.11.2 is precisely 13mm. It is measured between the two spring bars that fit into the case lugs, excluding the lateral pins. This dimension is specific to the 25mm model and does not correspond to more common standards such as 20mm or 22mm, therefore requiring careful attention when selecting compatible straps.

For the Lyre L4.259.4.11.2, straps that respect the compact proportions of the case are recommended: alligator with vegetable tanning for formal occasions, anilina calf for daily wear, shell cordovan for those who appreciate natural patina, or vulcanised rubber for discreet functionality. Materials should enhance the minimalist elegance without visual overload.

Strap replacement requires removal of the spring bars: use a spring bar tool to gently push the small retaining lever, then extract the bar from the case. Repeat on the other side, then insert the new strap by sliding the bars into the case lugs until they click securely. Avoid forcing to prevent damage to the lug attachments.

Yes, it is possible. The Longines Lyre L4.259.4.11.2 accepts any strap with 13mm lugs provided that the strap shoulders (the sections adjacent to the spring bars) are proportioned to the case width. Milano Straps offers handcrafted 13mm straps compatible with the same thickness and finish, guaranteeing precision in fitting.

The lifespan of a leather strap depends on the material and usage: anilina calf has an average life of 2–4 years with daily use; alligator with vegetable tanning lasts 4–6 years; shell cordovan can exceed 6–8 years due to fibre density. Determining factors include humidity, sun exposure, and frequency of strap changes. Careful maintenance (cleaning and periodic conditioning) significantly extends durability.
