Strap for Navy Watch Navy Black / Stainless Steel / Black

The Laco Navy Watches 861615 features a lug width of 18 millimetres. This measurement represents the distance between the inner pins that secure the strap to the case. To verify compatibility, use a calliper to measure the space between the pins: it must correspond exactly to 18mm. An incorrect measurement would result in improper fitment or difficulty inserting the strap.

The choice of strap depends on intended use. For daily elegance, we recommend alligator or calf leather with vegetable tanning, which develop a natural patina over time. For marine or sporting environments, nylon NATO or vulcanised rubber offer waterproofing and durability. Each material maintains visual balance with the compact 36mm case.

Strap replacement requires two tools: a spring bar tool and a light source. Position the watch on a soft surface to prevent scratches. Insert the spring bar tool into the pin hole, gently push to compress the internal spring, and slide the pin outward. Repeat on the other side. Insert the new strap's pins into the lugs and press until they click into position.

Any strap with an 18mm lug width is compatible with the Laco Navy Watches 861615. You can choose from specialist strap manufacturers offering premium materials such as alligator, shell cordovan, vegetable-tanned calf, nylon NATO, and vulcanised rubber. Always verify the lug width before purchase by consulting the specific 18mm catalogue.

The lifespan of a leather strap depends on the material and usage. Vegetable-tanned calf leather typically lasts 18-24 months with daily wear, developing an aged patina. Alligator has greater longevity, up to 3 years. Vulcanised rubber lasts 2-3 years under intensive use. Protecting the strap from excessive moisture and dirt extends its useful life.
