FAQ
What is the lug width of the Laco Navy Watches 862090?
The Laco Navy Watches 862090 is equipped with 18mm lugs. This lug width is critical for correct strap attachment: a strap with lugs not precisely 18mm may cause friction on the case pins or generate dangerous play during daily wear.
Which strap is best for the Laco 862090?
For the Laco 862090, we recommend straps in vegetable-tanned leather (calf or alligator) in black or dark brown tones. These materials respect the sober and functional character of the German watch, allowing natural patina development over time. For sporty contexts, a cotton-polyamide NATO strap or an FKM rubber strap offer practicality and water resistance without aesthetic compromise.
How do I change the strap on the Laco Navy Watches 862090?
To change the strap on the 862090, position the watch on a silicone mat with the case facing up. Use a spring bar tool to apply gentle inward pressure on one of the two pins (spring bars) that hold the strap to the lugs. When the pin yields slightly, remove the strap. Repeat on the other side. To install the new strap, align the lugs with the pins and gently insert the pin into the hole, ensuring both sides are fully seated in the spring groove.
Can I use an aftermarket strap with 18mm lugs?
Yes, any strap with 18mm lugs is compatible with the Laco 862090, provided the lugs are made of stainless steel or equivalent material and correctly dimensioned. Milano Straps' artisanal straps are designed and tested for this lug width, guaranteeing precise fit to the case pins without friction or play.
What is the lifespan of a leather strap for the Laco 862090?
A vegetable-tanned leather strap with 18mm lugs has a typical lifespan of 2–4 years with daily wear, depending on exposure to moisture, perspiration and climate conditions. The leather develops a natural patina that improves its appearance in the first year; deterioration accelerates after 3–4 years if frequently exposed to water. With proper maintenance (periodic cleaning, drying after moisture contact), the lifespan can extend beyond 4 years.
