Strap for Elegant Collection Automatic 37 Stainless Steel / Grey / Bracelet

The lug width of the Longines Elegant L4.810.4.72.6 is 19 millimetres. This measurement represents the distance between the inner shoulders of the two lugs on the case and is critical for strap compatibility. When measuring lugs, it is essential to use a metal ruler positioned on the inner shoulders, avoiding errors that could result in incompatible straps or excessive play.

For the Longines Elegant L4.810.4.72.6, alligator leather represents the solution of aesthetic and functional excellence. The natural grain of the leather creates discrete luminous effects that complement the satinised case subtly. Alternatively, vegetable-tanned calf leather offers evolving patina and reliability, whilst Cordura NATO in anthracite-grey provides contemporary versatility whilst maintaining the formal tone of the timepiece. The choice depends on intended use and personal colour preferences.

The Longines Elegant L4.810.4.72.6 is fitted with standard 19-millimetre lugs. Strap change is accomplished by inserting appropriate tools (spring bar tool or pin extractors) into the lateral holes of the case, compressing the internal springs that secure the strap in position. Once the previous strap is removed, insert the new strap by aligning the holes with the retractable pins. This operation requires care to avoid scratching the case. If uncertain, consult a professional watchmaker.

Yes, any strap with a 19-millimetre lug width is compatible with the Longines Elegant L4.810.4.72.6. High-quality artisanal aftermarket straps, crafted in alligator, vegetable-tanned calf or NATO, fit perfectly to the original lugs. It is essential to verify that the strap is genuinely 19 millimetres, as even minor variations compromise alignment and stability. Online at milanostraps.it, 19mm straps are available specifically selected and verified for compatibility.

The lifespan of a leather strap on a Longines Elegant L4.810.4.72.6 depends on the material and usage. A high-quality artisanal strap in alligator or vegetable-tanned calf, with vegetable tanning and precise finishing, maintains structural and aesthetic integrity for 3–5 years of daily wear, developing a patina that enriches its character. Factors such as perspiration exposure, moisture and mechanical stress accelerate ageing. Periodic maintenance with specific balms and seasonal rotation of straps significantly extend the useful life of the piece.
