Frequently asked questions

What is the exact lug width of the Longines Lyre L4.961.2.11.7?

The lug width of the Longines Lyre L4.961.2.11.7 is 21 millimetres. This lug width is specific to this model and requires customised 21mm straps to ensure proper fit between the case and strap, preventing excessive play or tension.

Which strap material pairs best with the Longines Lyre L4.961.2.11.7?

For the Longines Lyre L4.961.2.11.7, we recommend Nile alligator with vegetable tanning for the most refined aesthetic contrast, European calf leather with vegetable tanning for patina that evolves over time, or shell cordovan for unparalleled density and light reflection. Your choice depends on daily wear and dial tone.

How do you correctly change the strap on a Longines Lyre L4.961.2.11.7?

The Longines Lyre L4.961.2.11.7 uses standard spring bar mechanisms. Position the spring bar tool (typically located at the rear of the lug) inward, press gently to release, and slide the strap outward. For installation, insert the new 21mm strap by aligning the hole with the spring bar pins, then press until you hear the click. Never force the insertion.

Is the Longines Lyre L4.961.2.11.7 compatible with standard aftermarket straps?

The Longines Lyre L4.961.2.11.7 requires specifically sized 21mm straps. Standard 20mm aftermarket straps will be undersized; 22mm straps will introduce unacceptable play. We recommend straps manufactured specifically for 21mm lug width, such as those available in the milanostraps.it catalogue.

What is the average lifespan of a leather strap on the Longines Lyre L4.961.2.11.7?

A quality leather strap, crafted in alligator with vegetable tanning or European calf, maintains structural integrity for 3–5 years with moderate daily wear. Lifespan depends on ambient humidity, frequency of wear, and leather care. Straps made from premium leathers and artisanal stitching tend toward the higher end of this range.
