Strap for Lyre 25 Quartz Yellow

The Longines Lyre L4.259.2.11.7 features an exact lug width of 13mm. This measurement is precise and admits no variation: a 14mm or 12mm strap will not fit correctly. To verify, measure with a ruler from the inner side of one lug to the other, perpendicular to the case.

The ideal strap for the Lyre is vegetable-tanned alligator in dark shades (black, tobacco brown) or shell cordovan burgundy. Alternatively, French Taurillon leather in black or brown. We advise against synthetics: natural leathers adapt to the wrist and age with elegance, developing unique patina over time.

The Lyre uses straight spring bars. Remove the bar using a dedicated tool (spring bar tool) by gently pressing on one side of the spring. Insert the new strap by aligning the bar holes with the case lugs, then reinsert the spring ensuring it is securely fastened on both sides.

No, absolutely not. A 14mm or 12mm strap does not fit the Lyre's 13mm lugs. Forcing it causes permanent damage to the case and lugs. Compatible 13mm straps are available online and through the Casati Milano atelier, which produces custom straps guaranteeing perfect fit.

A quality leather strap (alligator, cordovan, vegetable-tanned calf) lasts 3-5 years with daily wear, longer if rotated. Vegetable tanning allows greater longevity than chrome tanning. The patina that develops increases aesthetic value. Casati Milano offers an 18-month guarantee and maintenance services to extend useful life.
