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

The lug width of the Longines Elegant L4.310.0.87.6 is 16mm. This measurement represents the internal distance between the two spring bars that hold the strap in place. It is essential to verify this dimension before purchasing an aftermarket strap to ensure perfect compatibility and eliminate any gap between the case and strap.

For the 29mm Longines Elegant L4.310.0.87.6, the most recommended straps are in black or dark brown alligator for formal occasions, vegetable-tanned calf for versatile daily wear, or shell cordovan for those seeking superior quality and natural ageing. The choice depends on intended use and personal colour preferences, and you can alternate multiple straps on the same watch.

To change the strap, remove the spring bars holding it in place: use a dedicated spring bar tool to lift the small lever on the bar, extracting it gently. Once the case is free, align the new strap's holes with the bars, lowering the lever until you hear the click indicating correct positioning. Proceed carefully to avoid scratching the case.

Yes, you can use aftermarket straps compatible with 16mm lug width on your Longines Elegant L4.310.0.87.6. The important factor is verifying the exact measurement (16mm) and build quality, preferably artisanal leather straps with professional finishing that respect the watch's refined aesthetic. Specialised brands ensure durability and optimal compatibility.

The lifespan of a leather strap depends on the material chosen, frequency of use, and maintenance. A quality alligator strap lasts 3-5 years with daily wear, whilst calf has similar longevity. Shell cordovan, owing to its superior elastic properties, can last 5-7 years. Regular maintenance (cleaning, occasional conditioning with specific oils) significantly extends strap life.
