Strap for Lyre 35 Quartz Stainless Steel

The lug width of the Longines Lyre L4.759.4.12.2 is 18 millimetres. This measurement represents the distance between the two lugs where the strap attaches to the case. It is essential to respect this specification to ensure proper strap fitment and maintain the watch's aesthetic proportions.

For a 35mm ladies' watch like the Lyre, fine materials are paramount: alligator leather with vegetable tanning represents the most elegant choice, featuring natural grain and evolving patina over time. Shell cordovan in burgundy or havana tones is excellent for those desiring a strap that improves with age. Smooth veal leather in neutral tones (black, brown, cream) offers formal versatility. NATO and rubber are practical, informal alternatives.

The strap is changed by unscrewing the spring bars that secure it to the case lugs. Use a dedicated spring bar tool to insert the micro-lever into the lateral hole of the spring bar, releasing tension. Remove the old strap gently and insert the new one, verifying that the spring bars are firmly seated. Alternatively, a skilled watchmaker can perform the operation with care to prevent case damage.

Yes, provided the strap is specifically manufactured for 18mm lug width. However, it is essential to verify that the spring bars match the original in length and diameter. Artisanal straps from specialised manufacturers guarantee precise compatibility. Be cautious of generic straps: even minor variations (16mm or 20mm) prevent proper attachment.

The lifespan of a leather strap depends on material quality, frequency of use, and maintenance. High-quality artisanal alligator or shell cordovan resists 5-8 years with daily wear, developing natural patina and character. Classic veal leather has similar longevity (5-7 years). Factors shortening lifespan: prolonged moisture, excessive perspiration, lack of rotation with other straps. Regular cleaning with a soft cloth and storage in a dry environment significantly extends durability.
