FAQ
What is the lug width of the Longines Lyre L4.961.4.12.6?
The lug width of the Longines Lyre L4.961.4.12.6 is 21 millimetres. This specific measurement represents the distance between the two attachment points of the strap on the case and requires dedicated straps of this exact dimension. It is incompatible with standard 20 or 22 millimetre straps, which would create visible gaps and accelerated wear on the lugs.
Which strap is recommended for the Longines Lyre L4.961.4.12.6?
The Longines Lyre L4.961.4.12.6, given its hybrid nature between dress watch and tool watch, pairs ideally with black alligator for formality, vegetable-tanned calf in cognac tones for daily character, shell cordovan for those seeking durability and natural lustre, or textile NATO straps to emphasise the military heritage. Selection depends on your specific dial variant and primary use case.
How do you change the strap on a Longines Lyre L4.961.4.12.6?
Strap replacement requires a dedicated tool: a spring bar tool with a flat, gentle tip. Insert the tip beneath the pin securing the strap to the lug, apply gentle pressure to compress the internal spring, and extract the pin. Once removed, the strap detaches easily. To install the new strap, align the hole with the lug, insert the pin, and verify secure engagement. Exercise caution on steel cases to avoid scratching the lugs.
Is the Longines Lyre L4.961.4.12.6 compatible with quality aftermarket straps?
Yes, the L4.961.4.12.6 is fully compatible with bespoke aftermarket straps provided they are constructed with a 21 millimetre lug width. Custom straps from specialised ateliers, such as Casati Milano, deliver superior build quality compared to OEM Longines straps, with options for leather selection, personalised length adjustment, and extended durability warranties.
How long does a leather strap last on a Longines watch like the L4.961.4.12.6?
The lifespan of a leather strap depends on leather type, usage frequency, and environmental exposure. A quality-crafted alligator or shell cordovan strap, with routine care, lasts 3–5 years of daily wear. Vegetable-tanned calf develops accelerated patina in the first 12 months, then stabilises to 2–4 years of service. Direct sunlight, saltwater, and persistent humidity reduce longevity by 30–40%. Specialist ateliers typically guarantee 18 months against manufacturing defects.
