Strap for Record 26mm Stainless Steel / Black-Diamond / Bracelet

The lug width of the Longines Record L2.320.4.57.6 is 20mm. This dimension is measured between the two vertical lugs that anchor the strap to the case. It should not be confused with the case diameter, which is 26mm on this model. To verify compatibility, use a calliper or ruler to accurately measure the distance between the lug terminals.

For the Longines Record L2.320.4.57.6, the most suitable straps maintain balanced proportions. Genuine alligator in slim thickness (4-5mm) is the classic choice to avoid weighing down the 26mm case. Vegetable-tanned calf leather offers natural patina over time. Polished shell cordovan imparts sophistication. For a sporty aesthetic, a woven NATO strap in neutral tones is ideal. Structured butyl rubber guarantees technical versatility.

The Longines Record L2.320.4.57.6 uses the traditional removable spring bar system. Remove the old strap by gently pushing the spring bar to one side with an appropriate tool (spring bar removal tool), extract the strap, and insert the new one by aligning the terminal holes with the bars. Ensure the spring bar is firmly positioned on both sides. If unsure, entrust the strap change to a professional service to avoid case damage.

Yes. Any strap with a 20mm lug width is compatible with the Longines Record L2.320.4.57.6, regardless of brand. Compatibility depends solely on lug width (20mm in this case). However, to achieve harmonious proportions with a 26mm case, we recommend straps in contained thickness (no more than 6mm) and in leather or flexible materials. Always verify the lug width before purchase to avoid incompatibility.

The lifespan of a leather strap depends on usage, climatic conditions, and material. A quality alligator or shell cordovan strap, worn regularly on a compact watch like the Record, maintains structural integrity for 3-5 years. Leather develops natural patina and minor creasing is normal. Humidity and sun exposure accelerate ageing. To extend lifespan, avoid prolonged immersion and store in a dry environment. Artisanal vegetable-tanned straps, renewed every 2-3 years, guarantee optimal performance over time.
