About Laco
Frieda Lacher and Ludwig Hummel opened their workshop in Pforzheim in 1925. The Laco brand came from the alliance with Durowe, Hummel's movement maker, in the mid-1930s. It was one of the five suppliers of the large 55 mm B-Uhr observation watches.
Laco still makes pilot's watches with type A or type B dials, in smaller sizes for everyday wear.
