Strap for Heritage Diver

The Longines Heritage L2.795.4.52.0 has a lug width of 20mm. This is the standard measurement for Heritage models of this generation and ensures correct proportions between the 43mm case and the strap. The distance between the lugs is approximately 49-50mm, so a strap of exactly 20mm width maintains the aesthetic and mechanical balance designed by Longines.

For the Longines Heritage L2.795.4.52.0, straps in alligator, shell cordovan, or vegetable-tanned calf are recommended, as they amplify the vintage-sporting character of the case and recall the instrumental origins of the model. Alligator offers authentic 1960s grain texture, whilst shell cordovan develops a deep patina over time. Vegetable-tanned calf is versatile and creates elegant day-to-evening pairings. For nautical or sporting contexts, fabric NATO straps remain faithful to the military heritage of the chronograph.

Strap replacement is performed by releasing the spring bar pins from the lugs of the case. Position the watch with the case facing upward, use a dedicated tool (spring bar tool) to compress the internal spring of the pin and slide it out of the lug. Repeat on both sides. The new strap must be exactly 20mm in width and must fit between the lugs without forcing. If unfamiliar with the procedure, contact Casati Milano for professional installation.

Yes, any 20mm-width strap is compatible with the Longines Heritage L2.795.4.52.0. MilanoStraps artisanal straps are crafted from superior-quality leather and customisable in measurements, materials, colours, and finishes. Compatibility is guaranteed for thickness and buckle or deployante construction, which adapt to standard 20mm spring bars.

The lifespan of an artisanal leather strap depends on use, maintenance, and material. Under normal conditions, a high-quality alligator or shell cordovan strap lasts 3–5 years, whilst softer calf leather may last 2–3 years. Leather develops patina and character through natural ageing. To extend durability, avoid prolonged moisture, keep the strap clean and dry, and periodically rotate with other straps. MilanoStraps guarantees 18 months on the artisanal work of Casati Milano.
