Strap for Elegant Collection Automatic 37 Stainless Steel / White / Strap

The lug width of the Longines Elegant L4.810.4.12.2 is 19mm. This measurement is the distance between the two lugs that attach the strap to the watch case and determines compatibility with aftermarket straps. It is essential to verify that any strap you choose has exactly this width to ensure correct and secure installation.

For the Longines Elegant L4.810.4.12.2, alligator in French tanning remains the excellent choice due to its natural texture and formal character. Shell cordovan offers a deep patina that evolves over time, whilst calf leather in vegetable tanning provides an authentic and accessible alternative. Structured rubber is ideal for a more informal approach without compromising the classical proportions of the case.

To change the strap, you must remove the spring bars (small metal pins) at the ends of the case using a spring bar tool or dedicated device. Extract the bars from the old strap, then insert them into the new one, ensuring it is perfectly aligned with the lugs. The width of 19mm must correspond exactly. If you are uncertain, consult a professional watchmaker.

Yes, you can use quality aftermarket straps compatible with the 19mm lug width. Artisanal straps in alligator, shell cordovan, or calf offer greater stylistic choice than original Longines options. Ensure the strap is made by reputable manufacturers and that the width is exactly 19mm to guarantee perfect and secure fit.

The lifespan of a leather strap depends on use and material quality. A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) can last 3 to 8 years with regular maintenance. Daily use, sun exposure, and humidity reduce longevity. The standard warranty on artisanal straps is typically 18 months, during which the manufacturer covers manufacturing defects.
