Strap for Skin Diver Stainless Steel / Black / Calf

The lug width (ansa width) of the Longines Heritage L2.822.4.56.2 is 22 millimetres. This measurement represents the internal distance between the case lugs and is the fundamental parameter for selecting a compatible strap. You can verify it by measuring the case directly with a digital calliper or consulting the official Longines documentation.

The Longines Heritage L2.822.4.56.2, for stylistic and functional coherence, performs best with a strap in vegetable-tanned leather or alligator. Tuscan honey-burnished leather offers an evolving patina over time and authentic dialogue with the Heritage spirit. Alligator provides elegant texture and natural sheen. For sports versatility, calfskin or nato straps in neutral tones remain entirely appropriate.

Strap replacement is achieved by removing the spring bars that connect the strap to the case. Use a specific tool (strap splay or spring bar tool) to slightly expand the bar and extract it from one end. Repeat the operation on the other side. Then insert the spring bars of the new strap in the same positions, ensuring they are positioned securely. If unfamiliar with the procedure, consult a professional watchmaker.

Not all 22mm straps are identical: compatibility depends on the shape and total length of the strap, as well as the position of the anchor holes. Handcrafted straps from Milano Straps are made specifically for watches with 22mm lugs and guarantee correct fit with the Longines case. We recommend verifying the overall length (bracelet plus soft part) before purchase to ensure comfort on the wrist.

The lifespan of a leather strap depends on the quality of tanning, the material chosen, and frequency of use. A high-quality artisanal vegetable-tanned leather strap, under normal conditions (4-5 days per week), maintains structural and aesthetic integrity between 3 and 5 years. Alligator and shell cordovan extend beyond 5-7 years due to the natural robustness of the fibre. Casati Milano's 18-month warranty covers manufacturing defects and ensures proven reliability over time.
