Strap for Elegant Collection Automatic 29 Stainless Steel / Grey / Strap

The lug width of the Longines Elegant L4.310.4.72.2 is exactly 20 millimetres. This is the precise measurement required to ensure perfect fit with the watch's lugs. A 18mm strap will enter with excessive play, whilst a 22mm strap will not fit at all. Lug width is measured in the interior space between the two lugs, from wall to wall, using a ruler or calliper.

The optimal choice is an alligator strap with vegetable tanning, ideally in dark brown or black for dark dials, or burgundy or medium brown for silver dials. Alligator perfectly reflects the elegant identity of the watch and develops a noble patina over time. Alternatively, a calf leather strap with fine grain and vegetable tanning offers chromatic versatility whilst maintaining aesthetic restraint.

The Longines Elegant L4.310.4.72.2 uses a straight lugs system. To change the strap, position the watch on a soft cloth, locate the pin or spring that connects the strap to the lug, and using a dedicated tool (a spring bar tool or small screwdriver), gently lift the fastening upward. Once the pin is extracted, the strap detaches. Repeat on the opposite side. To install a new strap, reinsert the pin ensuring it enters correctly into the holes on both sides.

Yes, absolutely. Since Longines rarely provides its own straps as separate replacement parts, aftermarket straps are an ideal and recommended solution. Simply ensure that the lug width is exactly 20mm and that the aesthetic style is coherent with the watch's elegant identity. Straps in alligator, calf leather with vegetable tanning, or natural rubber maintain elegance without compromising the original design.

The lifespan of a leather strap depends on the quality of tanning, frequency of use, and care. An alligator strap with vegetable tanning, worn daily in non-aquatic settings, typically lasts 4–6 years before showing visible wear (colour fading, crease marks). Comparable-quality calf leather lasts 3–5 years. Exposure to direct sunlight, persistent humidity, and water significantly shortens useful life. By rotating between multiple straps and cleaning regularly, longevity can be extended.
