Laco Watch Navy Valencia 42 861651.2. Just like the aviator watches, the Laco maritime watches allow you to hold one thing in particular in your hands: a piece of history. Both the aviator watches and the maritime watches from Laco look back on a legendary past and a rich history. The requirements to start constructing them came from the German Marine Observatory in Hamburg, and only a few factories were able to fulfil them in the 1940s. Laco was one of those companies. Today's watches are still oriented toward the look of yesteryear in their appearance. Thus, with a maritime watch from Laco watch manufacturing you always have a piece of history made in Germany in sight.
