The official chronometer-certified Longines L888.5 caliber delivers precision, while water resistance reaches 30 meters for daily wear.

Frequently asked questions

What is the lug width of the Longines Lyre L4.361.1.12.7?

The Longines Lyre L4.361.1.12.7 features a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 15mm, meaning the distance between the case lugs is precisely 15 millimetres. This width is standard for women's watches below 34mm in diameter and ensures perfect visual proportions on the Lyre model. A 15mm strap fits correctly into the lugs without gaps or width excess.

Which strap is best suited to the Longines Lyre L4.361.1.12.7?

Black <a href="/pages/termine-glossario/alligatore">alligator</a> is the historically correct and stylistically coherent choice: its fine grain pattern dialogues perfectly with the white dial and brushed steel case. Alternatively, calf leather with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> in dark brown offers warmth and develops a noble patina. For a contemporary interpretation, dark Japanese <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> maintains formal elegance with a unique texture and predictable chromatic evolution.

How do you change the strap on a Longines Lyre L4.361.1.12.7?

The Lyre L4.361.1.12.7 strap is changed by removing the two lateral pins (one per side) that connect the lugs to the case. Use a dedicated spring bar tool to gently compress the internal spring of each pin and slide it out. Insert the new 15mm strap, align the holes, and reinsert the pins until they click into place. The process takes minutes and can be done independently with basic tools.

Is an aftermarket 15mm strap compatible with the Longines Lyre L4.361.1.12.7?

Yes, any strap designed for 15mm lugs is mechanically compatible with the Lyre L4.361.1.12.7. Compatibility is guaranteed by the standard pin diameter and strap width. However, to maximise aesthetics, choose straps that respect the elegant, minimalist spirit of the Lyre: noble materials such as alligator, calf, and shell cordovan maintain the original visual harmony.

How long does a leather strap last on a Longines Lyre L4.361.1.12.7?

A quality leather strap (alligator, calf, or shell cordovan) with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> lasts 3–5 years with moderate daily use, provided it is properly maintained: dried quickly if wet, protected from excessive heat and permanent creasing. Alligator is more resistant to scratches; calf tends to develop a noble patina. A fine leather strap is not disposable: it ages and softens, acquiring personal character over time.
