Strap for Lyre 30 Automatic Stainless Steel / Blue / Bracelet

The lug width (or anse width) of the Longines Lyre L4.361.4.92.6 is 15mm. This dimension falls outside standard industrial specifications (typically 16mm or 18mm) but represents a deliberate constructive choice for this model to maintain harmonious proportions with the 30mm case. It is essential to verify this measurement precisely when purchasing a replacement strap.

Polished alligator represents the most natural solution: the geometric texture of the scutes enhances the minimalist aesthetics of the case and dial design without visual competition. For those desiring an evolving patina over time, horse shell cordovan offers authentic chromatic depth with progressive consolidation of the leather. Structured calf leather suits those preferring contemporary finishes and formal precision.

Removal is accomplished by extracting the spring bars (or spigots) from the lugs using a specialised dual-ended tool. Position the elastic pin so the internal spring compresses, withdraw it gently from its seat, remove the worn strap, and insert the new one by aligning the holes. This operation is straightforward but requires care to avoid scratching the lugs.

Yes, provided the lug width is precisely 15mm. Milano Straps offers a curated collection of 15mm artisanal straps in various materials (alligator, cordovan, calf) specifically engineered for compatibility. It is essential to avoid dimensionally approximate straps that would compromise case stability and overall aesthetics.

A quality alligator or calf strap in normal conditions typically lasts 3–5 years before replacement becomes necessary, though natural leather evolves throughout this period. Shell cordovan tends to endure longer, up to 7–8 years, owing to the density of the dermis. Frequent use in humid environments or prolonged sun exposure accelerates fibre degradation.
