Strap for Lyre 25 Quartz Stainless Steel

The lug width of the Longines Lyre L4.259.4.72.6 is 13 millimetres. This measurement refers to the distance between the lug attachment pins on the case. To measure correctly, position a digital calliper inside the attachment seats, from the bottom of one hole to the other, ensuring a tolerance of ±0.5mm for proper strap compatibility.

The best strap depends on intended use and aesthetic preference. For historical stylistic coherence, we recommend alligator leather with vegetable tanning in black or dark brown, which emphasises the case's clean lines. For durability and aesthetic ageing, shell cordovan in cognac or brown tones is excellent. For daily practicality, a cotton NATO or technical rubber strap offers comfort without maintenance requirements. All 13mm straps are available on milanostraps.it.

Strap replacement requires two tools: a spring bar tool and a soft work surface. Position the watch with lugs facing upward, insert the tool's tip into the spring mechanism's groove, apply gentle downward pressure to release the pin, and slide off the old strap. Repeat on the opposite side. To fit the new strap, align the pin with the seat and press until it clicks into place. Avoid forcing the spring to prevent damage.

Yes, any strap with a 13mm lug width is compatible with the L4.259.4.72.6, provided the anchor pin is standard (typically 1.2mm diameter) and the buckle or deployant folding clasp seat allows smooth passage without excessive play. All 13mm straps on milanostraps.it are tested for compatibility with Longines models and offer customisations in sizing, leather choice, and stitching thread colour.

A quality leather strap (alligator with vegetable tanning, anilina calf, or shell cordovan) maintains functional characteristics for 4–6 years with regular daily wear. Longevity depends on frequency of use, moisture exposure, and maintenance. Shell cordovan typically lasts longer (6–8 years) due to fibre density. Preventative treatment with neutral balm every 6–8 months significantly extends useful life. Casati Milano atelier provides an 18-month warranty on every personalised strap.
