Strap for Lyre 25 Automatic Stainless Steel

The lug width of the Longines Lyre L4.260.4.72.6 is 13 millimetres. This measurement is specific to this model and represents a deliberate design choice to maintain harmonious proportions with the 25mm case diameter. Always verify the specification with a digital calliper before purchasing an aftermarket strap.

For this elegant ladies' timepiece, we recommend Mississippi alligator straps for their fine grain and natural brilliance. Vegetable-tanned calf leather is an excellent choice for those who appreciate chromatic evolution over time. Horsebutt cordovan is also a sophisticated pairing, offering inherent compactness and lustre. Avoid excessively thick straps that could compromise the case proportions.

To change the strap, obtain a spring bar tool. Position the watch with lugs facing downward. Insert the tool's tip into the spring groove beneath the lug, compress it towards the centre, and slide the lug away. Repeat on the opposite side. When reinstalling, align the pins with the holes and insert them individually, ensuring the spring mechanism clicks into place. If uncertain, consult a professional watchmaker.

Yes, you may use aftermarket straps compatible with the 13mm lug width specification. Ensure the strap has been manufactured specifically for this width, as 13mm is not a common industrial standard. Professional straps from MilanoStraps offer guaranteed compatibility and custom sizing for your L4.260.4.72.6.

Leather strap longevity depends on the hide species and daily use intensity. Vegetable-tanned calf typically lasts 3-5 years with regular maintenance. Alligator, owing to scale robustness, frequently exceeds 5 years. Horsebutt cordovan, an exceptionally dense material, readily reaches 7-8 years of service. Sun exposure, perspiration, and humidity accelerate deterioration. Casati Milano provides an 18-month warranty on its bespoke straps.
