Strap for Record 30mm Stainless Steel / Black-Arabic / Bracelet

The lug width of the Longines Record L2.321.4.56.6 is 20 millimetres. This dimension is the critical parameter for strap compatibility: any strap mounted on the case must have an internal seat of 20mm to adhere perfectly to the attachment tubes without play or forcing.

The materials most coherent with the austere aesthetic of the Record are genuine alligator (structured grain), vegetable-tanned calf (noble ageing), and Japanese shell cordovan (natural lustre and durability). Vulcanised rubber remains the most practical option for daily wear, whilst NATO straps require selection in thin fibres to avoid visually overwhelming the 20mm lug width.

Strap replacement is achieved by extracting the attachment tubes (spring bars) from the case seat. With a dedicated tool or small flathead screwdriver, gently push the tube downward, releasing it from one side, then extract completely. The new strap is inserted by clicking the tube into the opposite seat, ensuring it is firmly anchored at both case corners.

Yes, provided they respect the 20-millimetre lug width and have a total length compatible with the 30mm case. Full-leather straps, alligator, calf, and rubber structured specifically for this measurement mount without adaptation. Manual verification of lug width before ordering is always recommended to exclude manufacturing tolerances.

A full-leather strap with vegetable tanning offers a lifespan of 3–5 years with moderate daily wear, depending on exposure to moisture and perspiration. Genuine alligator and shell cordovan maintain superior elasticity, extending life to 7–8 years. Vulcanised rubber exceeds 10 years if preserved from scratches and direct UV exposure. Leather ageing is a natural process that increases aesthetic value over time.
