FAQ

What is the exact lug width of the Longines Lyre L4.361.4.12.6?

The Longines Lyre L4.361.4.12.6 features a 15mm lug width, a specific and uncommon dimension that reflects classical feminine proportions from the 1990s. This width is essential for strap compatibility and should not be confused with contemporary 16mm or 18mm standards.

What is the best strap for the Longines Lyre L4.361.4.12.6?

For this timepiece, we recommend Nile alligator leather in vegetable tanning or Barenia calf: both preserve the watch's discreet elegance without visual competition. The material must suit slender wrists and avoid excessive thickness. Milano Straps offers personalised 15mm straps for every requirement.

How do I change the strap on the Longines Lyre L4.361.4.12.6 myself?

The Lyre uses 15mm lugs removed via small pins or spring bars. Position the watch on a soft support, use a strap tool or appropriate pin pusher to press the bar outward from underneath, then extract the lug. Insert the new strap by aligning the pins and press until the closure clicks. If uncertain, consult a specialised watchmaker.

Are aftermarket straps compatible with the Longines Lyre L4.361.4.12.6?

Yes, provided they respect the 15mm lug width. Milano Straps stocks high-quality aftermarket straps specifically catalogued for this width. Always verify the reference before purchase to prevent incompatibility; a 16mm strap will not install correctly.

How long does a leather strap last on a Longines Lyre?

An alligator or calf strap of good quality, under moderate daily use, lasts 3 to 5 years. Longevity depends on climate, frequency of use and maintenance. Vegetable-tanned leather develops natural patina over time, improving aesthetically. Milano Straps offers 18-month warranty on bespoke straps.
