Strap for Lyre 25 Automatic PVD Gold / White / Bracelet

The lug width of the Longines Lyre L4.360.2.12.8 is 13mm. This is a rare measurement in contemporary watchmaking, determined by the proportions of the 25mm case. To measure correctly, position a digital calliper perpendicular to the case lugs at the strap attachment point. A 13mm strap is the sole compatible choice for this model.

Alligator represents the premier choice for the Lyre: the fine texture of American crocodile naturally complements the delicate case proportions, creating visual coherence and sophistication. Vegetable-tanned calf is a valid alternative for daily wear, with a natural grain that develops over time. For formal occasions, black crocodile calf amplifies restrained elegance.

Changing the strap on the Lyre requires specialised tools: a pin remover or precision implement for the lugs, a soft work surface to protect the case finish, and care. Remove the spring bars by sliding the old strap shoulders downward. Insert the new strap, aligning it perfectly with the lug seats, then reposition the spring bars from top to bottom, ensuring the strap sits fully flush. If inexperienced, consult a qualified watchmaker.

Yes, aftermarket 13mm straps are fully compatible with the Lyre L4.360.2.12.8, provided they respect the precise lug width. Choose watchmaking specialists that guarantee construction accuracy and quality control. A well-crafted strap enhances your daily experience with the watch without aesthetic or functional compromise.

Longevity depends on material and usage. Quality alligator or vegetable-tanned calf lasts 3–5 years with regular use and proper care (avoid prolonged moisture, do not force bending). Rubber offers similar longevity with enhanced water resistance and minimal maintenance. Factors such as perspiration, humid climates and frequency of wear influence aging. A well-preserved strap develops a patina that increases its aesthetic value.
