Strap for Lyre 25 Automatic PVD Gold / White - Roman

The lug width of the Longines Lyre L4.360.1.11.7 is precisely 13mm. This measurement is specific to the 25mm case and represents the original manufacturing standard. Measurement should be performed using a digital calliper positioned perpendicularly inside the spring bar seat. Verifying this dimension before ordering ensures mechanical compatibility and aesthetic harmony.

Alligator remains the most coherent choice aesthetically and constructively, due to its regular scales and refined texture that complement the diminutive case naturally. Shell cordovan with vegetable tanning offers a sophisticated alternative, developing a unique patina over time. High-quality calf leather with lined finish permits versatile combinations, whilst rubber represents the ideal technical solution for intensive daily wear without compromising elegance.

Changing the strap on the Longines Lyre L4.360.1.11.7 requires a spring bar tool and deliberate execution, as the 25mm case features particularly minute lugs. Position the watch on a soft mat, identify the small lateral pins holding the spring bar, and compress the spring using the dedicated tool whilst sliding the strap outward. Once extracted, insert the new strap into the seat, ensuring the spring bar clicks securely. Many collectors prefer entrusting this operation to professionals to prevent lug damage.

Yes, any strap with 13mm lug width is mechanically compatible with the Longines Lyre L4.360.1.11.7, though it is essential to verify that it is specifically dimensioned for this case. Aftermarket straps not explicitly calibrated may prove excessively long or present disharmonious proportions. MilanoStraps offers a dedicated collection for 13mm widths, with straps tested for compatibility and aesthetic proportion with this 25mm case. Casati Milano's 18-month warranty covers the strap for potential future adjustments.

The durability of a natural leather strap depends upon material and usage patterns. Alligator and shell cordovan, if subjected to ordinary maintenance (periodic cleaning, protection from excessive moisture), retain structural integrity for 5-8 years. High-quality calf achieves 3-5 years of daily wear. Factors such as frequency of use, water and humidity exposure, and personal care significantly impact longevity. MilanoStraps warrants its straps for 18 months; replacement of spring bars or minor repairs are executed without charge during this period.
