Strap for Lyre 35 Automatic Yellow

The lug width of the Longines Lyre L4.860.2.12.8 is 18 millimetres. This measurement represents the distance between the contact points of the spring bars on the 35mm case. To verify it, remove the original strap and measure the width of the lug with a digital calliper positioned perpendicular to it.

For the Lyre, an alligator strap with vegetable tanning in brown or black tones is recommended, as it enhances classical elegance and the proportion of the 35mm case. Shell cordovan represents a premium alternative with superior patina development. Grain calf is perfect for those desiring minimal maintenance whilst maintaining formal character.

To change the strap, position the watch on a soft surface. Use a spring bar tool to press the spring bar inward and release the strap from the case. Insert the spring bar into the new strap and secure to the lugs. This procedure applies universally to 18mm lug width watches.

Yes, the Lyre accepts any aftermarket strap equipped with standard spring bars for 18 millimetre lug width. You may choose from materials such as alligator, shell cordovan, calf leather and canvas, guaranteeing full compatibility with the case.

A quality leather strap on a 35mm Lyre, subject to regular use (4–5 days per week), lasts approximately 18–36 months. Longevity depends on the tanning method, frequency of use and humidity exposure. Vegetable-tanned leather develops patina but wears more quickly than other finishes.
