Strap for Navy Watch Wilhelmshaven / Stainless Steel / White

The lug width of the Laco Navy Watches 861205 is 18mm. This measurement represents the distance between the two spring bars (perni) located at the ends of the case. It is essential to verify this dimension before purchasing an aftermarket strap, as an incompatible lug width will not fit correctly into the case holes.

For the 861205, we recommend straps in vegetable-tanned alligator leather, which develops a natural patina over time, or vegetable-tanned calf. For a style more closely aligned with its maritime heritage, a reinforced canvas or wool NATO strap is an excellent choice. For humid or intense marine environments, fluoroelastomer rubber ensures superior durability without functional compromises.

To change the strap: 1) Obtain a spring bar removal tool or small flat screwdriver. 2) Position the watch on a stable surface. 3) Insert the tool into the small hole of the spring bar and apply gentle pressure to release it. 4) Remove the old strap. 5) Insert the new strap by aligning the holes at the ends of the lugs. 6) Reinsert the spring bars with light pressure until they click into place.

All straps with an 18mm lug width are compatible with the 861205. At Milano Straps, you will find a selection of 18mm straps in leather (alligator, calf, shell cordovan), fabrics (NATO, military), and rubber. Always ensure the lug width is specified as 18mm and that the spring bars are compatible with the case width of your watch.

The longevity of a leather strap depends on intensity of use, climate, and maintenance. A naturally tanned leather strap, used daily under normal conditions, will typically last 2-4 years before showing significant signs of wear. Constant exposure to humidity, perspiration, and thermal variations shortens lifespan. Regular maintenance (periodic cleaning and conditioning) extends durability and develops a desirable characteristic patina.
