Strap for Navy Watch Casablanca / Stainless Steel / Superluminova

The lug width of the Laco Pilot Watches 861776.2 is 20mm. This measurement refers to the distance between the lugs (or spring bars) that secure the strap. Any aftermarket strap must feature lugs of exactly 20mm in width to ensure a precise fit and secure attachment. Always measure your watch's lugs before purchasing a replacement strap.

There is no single "best" strap; the choice depends on your intended use and personal aesthetic. For formal elegance, a vegetable-tanned leather strap (alligator or shell cordovan) develops character and patina over time. For tactical durability, a robust NATO fabric strap or FKM rubber provides constant grip and minimal maintenance. Structured calf leather offers an ideal balance between visual refinement and everyday resilience.

Strap replacement is straightforward and requires no specialised tools. Use a spring bar tool (or a small flathead screwdriver) to depress the metal spring bar that holds the original strap, then slide it out. Insert the new strap, aligning the holes with the spring bars, and allow the spring mechanism to resecure itself. Verify that your strap is 20mm wide and that the spring bar is fully seated before wearing the watch.

Yes, provided the strap features a 20mm lug width and has been constructed to artisanal quality standards. Specialised workshops such as Casati Milano produce bespoke straps that respect the proportions of your watch's case and the robustness of its construction. Avoid generic, low-quality straps: a Laco deserves materials and craftsmanship of the highest calibre.

Longevity depends on the type of leather, climate conditions, and intensity of wear. A shell cordovan or vegetable-tanned alligator strap may last 5–7 years with daily wear, developing an increasingly beautiful patina. Structured calf leather has a slightly shorter lifespan (3–5 years) if frequently exposed to moisture. A NATO fabric or rubber strap does not degrade and is essentially permanent if kept clean. Periodic lubrication extends the life of any leather strap considerably.
