Laco Watch Pilot Watch Original Graz Erbstuck 861946. A Laco watch is more than a watch. It is an expression of character. Because, no matter whether you wear a robust aviator watch, a precise chronograph or a timelessly elegant classic on your wrist, each Laco has a unique character, which is distinguished by the love of detail and passion, with which their watchmakers built it, with complex and sophisticated craftsmanship.
