Strap for Lyre 38.5 Automatic PVD Red / White / Bracelet

The lug width of the Longines Lyre L4.960.1.12.7 is 20 mm. This dimension represents the distance between the two lateral pins on which the strap is fitted and determines which strap width is compatible with the watch. For a precise measurement, use a digital calliper positioned perpendicularly to the case plane, excluding any curvature of the lugs.

For the Lyre we recommend three principal options: dark brown or black alligator for a formal, classical aesthetic that amplifies the watch's authority; Italian calf leather in vegetable tanning for daily versatility and natural patina that ages beautifully; shell cordovan for those seeking rarity with chromatic depth and naturally glossy surface. The choice depends on use: formal occasions call for alligator, daily wear favours calf leather, and sports applications prefer NATO straps.

To change the strap, position the watch on a soft surface with the case facing downwards. Use a spring bar tool to gently push the pin inwards, releasing one end of the strap from the first side. Repeat the operation on the other side. To fit the new 20 mm strap, align the holes with the pins and use the same tool to compress the pin whilst inserting it into the case, verifying correct anchoring from both sides.

Yes, provided the strap has a lug width of 20 mm. Aftermarket straps offer greater variety of materials and customisations compared to original Longines options. However, it is essential to verify construction quality: stitch rows must be straight and uniform, end finishes perfect, and the strap must remain rigid without loosening after the first weeks of use. Professional ateliers also guarantee adjustment of vertical dimensions to your wrist size.

A professionally crafted leather strap in alligator or vegetable-tanned calf has an average lifespan of 3-5 years under moderate daily wear. Longevity depends on several factors: sun exposure and humidity shorten useful life, whilst regular maintenance (gentle cleaning, protection from moisture) extends it significantly. Shell cordovan, owing to its natural density, can last 7-10 years. A NATO strap in canvas or acrylic fabric easily reaches 5-7 years of intensive use. The warranty offered by professional craftsmen (18 months with Casati Milano) covers manufacturing defects, not natural wear.
