Strap for Lyre 30 Automatic PVD Red / White - Roman / Bracelet

The lug width of the Longines Lyre L4.361.1.11.7 is 15mm, a specific dimension for this 30mm dress watch. Measured from the inner surface of one lug to the other, perpendicular to the case centre line, the width is exactly 15mm. This dimension does not coincide with standard widths (18mm, 20mm) and requires precise strap selection to maintain the visual balance characteristic of the Lyre.

For the Longines Lyre L4.361.1.11.7 we recommend primarily alligator leather in medium brown or cognac tones: the elegant grain and patina development over time create a perfect dialogue with the brushed steel case. Alternatively, vegetable-tanned calf leather offers softness and deep patina development, while shell cordovan represents the option for those viewing the strap as a twenty-year investment. The choice depends on intended use: formal, daily, or sporty.

Changing the strap on a watch with 15mm lugs requires a specific tool: a spring bar tool. Insert the small hook of the tool into the hole of the tension spring beneath the lug, compressing the spring toward the case until the lug is freed from the existing strap. Once one lug is extracted, remove the strap. Repeat the procedure symmetrically for the other side, always taking care not to scratch the case. Milano Straps recommends consulting a professional for the first replacement.

Yes, provided the lug width is exactly 15mm. Milano Straps offers a complete collection of artisanal 15mm straps compatible with the L4.361.1.11.7, customisable in material, colour, initials and thread colour. It is essential to verify dimensional compatibility: a lug that is too wide or too narrow compromises both aesthetics and correct load distribution on the wrist.

The lifespan of a natural leather strap varies based on material and usage. Genuine alligator with vegetable tanning, worn daily, maintains functionality and aesthetics for 5-8 years before requiring replacement. Shell cordovan, thanks to its density and natural resin, can exceed 10-15 years of use. Vegetable-tanned calf typically lasts 3-5 years with daily wear. Milano Straps offers an 18-month warranty on all straps and assistance with maintenance and replacement.
