This is a nice chronograph from Junghans with a Caliber j880.2 which is in fact a Valjoux 7750, a sturdy and precise mechanical movement. The design of the case and dial are from the famous Swiss architect and sculpter Max Bill (1908-1994).

The watch was originally released in the 1960's but its design is timeless and still considered beautiful by many. Junghans therefore rereleased the watch and it's still for sale new.
