Strap for Lyre 35 Automatic Stainless Steel

The lug width of the Longines Lyre L4.760.4.11.2 is 18 millimetres. This measurement represents the distance between the inner pins of the two lugs on the case and is essential for identifying compatible straps. Measuring the lug width correctly is crucial: use a digital calliper positioned between the inner pins to obtain the precise measurement, avoiding the common error of measuring the external diameter of the lugs themselves.

For the Longines Lyre L4.760.4.11.2, alligator represents the most traditional and elegant choice. The natural grain of the reptile skin creates a refined visual effect, and the leather develops a soft patina over time. Alternatively, vegetable-tanned calf leather offers a more casual yet equally sophisticated profile, with uniform grain creating clean lines. Shell cordovan is an unconventional yet fascinating choice for those seeking maximum durability and natural lustre.

To change the strap on your Longines Lyre L4.760.4.11.2, you will need a spring bar removal tool. Position the watch on a soft, stable surface and locate the horizontal pins connecting the strap to the lugs. Insert the tool tip gently under the pin and press upward to release it from one side. Remove the pin completely and repeat on the other side. Align the new strap with the lugs and reinsert the pins until you feel the locking click.

Yes, any strap with an 18mm lug width is compatible with the Longines Lyre L4.760.4.11.2. High-quality aftermarket straps—alligator, calf, shell cordovan, NATO, rubber—install using the same spring bars and guarantee total mechanical compatibility. The choice of material and thickness influences only aesthetics and tactile comfort, not structural functionality.

The lifespan of a leather strap depends on usage intensity, tanning method, and construction quality. A premium alligator or vegetable-tanned calf strap typically lasts between 3 and 5 years of daily wear, developing visible patina over time. Shell cordovan, being structurally more compact, can last up to 7-8 years. Regular maintenance—cleaning with a soft cloth, storage in a dry environment, alternating with other straps—significantly extends longevity. Undersized straps or those made from lower-quality leather show premature wear within 18-24 months.
