Strap for Elegant Collection Automatic 29 Stainless Steel / MOP / Bracelet

The lug width of the Longines Elegant L4.310.4.87.6 is 18 millimetres. This measurement is specific and not compatible with straps of other widths. To verify it, use a digital calliper positioned on the inner shoulder of the lugs, from the end of the spring bar on one lug to the corresponding end on the opposite lug. Our 18mm straps fit this model perfectly.

Alligator represents the classic choice par excellence for this model, thanks to its regular grain and natural tones that respect the minimalist aesthetic. Calf leather offers softness and versatility, ideal for those who prefer chromatic uniformity. Shell cordovan remains a niche option for those seeking durability and natural lustre. NATO fabric represents the lightweight sports alternative. We recommend evaluating the context of use: formal for black alligator, business casual for medium vitello.

The Longines Elegant L4.310.4.87.6 features removable lugs with spring bars. Obtain a specific lug removal tool or a small flat-head screwdriver. Position the watch with the caseback facing up and the strap in tension. Locate the small hole on each side of the case: push the spring bar towards the centre with the tool, reducing spring tension, and extract the old strap. To fit the new strap, align the lug holes with the case pins and push until you hear the spring's retention click.

The lifespan of a leather strap depends on frequency of wear, material quality and maintenance. For a Longines Elegant L4.310.4.87.6 worn daily, a handcrafted alligator or calf strap maintains structural integrity for 2–3 years. The material undergoes natural repetitive stress during wear, particularly at buckle level and fold zones. Exposure to moisture, perspiration and climatic variations accelerates deterioration. Straps from milanostraps.it carry an 18-month warranty. We recommend rotating among 2–3 different straps to distribute stress and extend the overall lifespan of each.
