Strap for Lyre 35 Automatic Stainless Steel

The lug width of the Longines Lyre L4.860.4.72.2 is precisely 18mm. This specialist dimension requires straps manufactured to specification and is incompatible with standard 20mm or 22mm straps. Always measure with a digital caliper positioned between the inner lug shoulders.

Vegetable-tanned alligator represents the optimal choice: natural grain texture dialogues perfectly with the case's classical geometry and 35mm proportion. An equally refined alternative is Fjord calf leather, which develops natural patina over time. Avoid NATO straps, which are visually incompatible with the model's understated elegance.

The procedure is straightforward: locate the two horizontal spring bars at the strap ends, use a thin lever tool to lift the pin, slide out the old strap and insert the new one by aligning it with the opposite lug. Avoid excessive twisting of the bars. When in doubt, consult a watchmaker.

Yes, any strap in 18mm width is compatible. Artisanal straps in vegetable-tanned leather or alligator offer superior quality compared to generic options and permit customization of length, colour and details. Always ensure thickness does not exceed 3-4mm to prevent lateral play.

A quality artisanal leather strap typically lasts 2-4 years under daily wear, depending on tanning method and sun exposure. Vegetable-tanned leather tends to last longer, whilst alligator develops patina yet remains durable. Protect the strap from prolonged moisture and occasionally apply leather balm to slow ageing.
