Strap for Lyre 38.5 Automatic PVD Red / White - Roman / Bracelet

The lug width of the Longines Lyre L4.960.1.11.7 is 20 millimetres. This is the distance between the two internal suspension pins of the case. It is essential to verify this measurement before ordering a strap, as even minimal tolerances (±1 mm) will cause visible misalignment or mounting difficulties. Measure with a digital calliper, perpendicular to the case body, with the watch clean.

Genuine alligator is the most elegant choice, particularly in dark brown or ivory tones. For superior value-for-money, calf leather with vegetable tanning offers natural ageing and patina development. If daily wear is intended, cotton NATO straps of aeronautical grade or vulcanised rubber provide practicality without aesthetic compromise. The Lyre, owing to its urban geometry, favours materials that mature over time rather than those that remain static.

Strap removal is performed by unscrewing the suspension pins (spring bars) with a dedicated tool: a two-pronged bar or a spring bar tool. Position the watch with the lug facing downward, insert the prong into the groove of the pin, apply gentle downward and lateral pressure to compress the internal spring, then extract the pin. Repeat for the opposite side. Mount the new strap by reversing the procedure, ensuring the pins seat symmetrically. If uncertain, consult a professional watchmaker.

Yes, any strap with a 20-millimetre lug width is compatible with the L4.960.1.11.7, provided it is crafted with artisanal quality. MilanoStraps offers a dedicated collection of 20mm straps, customisable in leather, hide, rubber, with choice of buckles and thread colour. For even more bespoke solutions, the Casati Milano atelier creates made-to-measure straps with direct consultation.

A quality leather strap, with vegetable tanning, typically lasts 3–5 years with daily wear, developing a natural patina characteristic of well-maintained objects. Longevity depends on exposure to perspiration, humidity, and climatic conditions. Premium alligator or calf straps can exceed 5–7 years whilst maintaining structural integrity. Minimal maintenance—periodic cleaning, protection from excessive humidity, natural air-drying—significantly extends strap lifespan.
