Strap for Lyre 25 Stainless Steel / White - Roman / Bracelet

The lug width of the Longines Lyre L4.360.4.11.6 is precisely 13 millimetres. This measurement must be verified by positioning a digital calliper between the inner lugs of the case, parallel to the horizontal diameter. Respecting this dimension is essential to avoid misalignment and premature wear on the lugs.

The ideal strap depends on use and personal preference. Alligator offers classic elegance with a natural texture that enhances the design; calf leather with vegetable tanning develops an authentic patina over time; shell cordovan provides structural solidity and natural lustre; fine rubber is perfect for light sports without sacrificing aesthetics. For formal contexts, deep black English calf is the most sophisticated choice.

Strap replacement requires a specific tool (spring bar tool) to compress the elastic pins that hold the strap to the case. Position the tool in the small lateral slot of the pin, apply gentle pressure to compress the spring, then extract the pin. Repeat on the other side. The reverse procedure secures the new strap. We recommend gentle pressure to avoid scratching the case or damaging the pins.

Yes, any strap with a 13mm lug width is mechanically compatible with the L4.360.4.11.6. High-quality aftermarket straps, such as artisanal ones made from alligator, calf leather or shell cordovan, offer superior aesthetic choice compared to OEM straps whilst maintaining full mechanical compatibility and ensuring longevity if crafted by specialist artisans.

A high-quality leather strap (alligator, calf, cordovan) typically lasts between 3 and 5 years with moderate daily use, depending on the tanning process and care. Leather straps with vegetable tanning develop a fascinating patina and can last longer if protected from excessive moisture. Fine rubber resists up to 7-10 years under normal conditions. Regular maintenance (cleaning, water protection) significantly extends longevity.
