The origins of the Nederlandse Uurwerkfabriek (NUFA) lie in Paauwe’s Volautomatische Kalenderuurwerken, a clockmaking company founded in Amsterdam in 1937. After the Second World War, clock production continued under the NUFA name. From 1947, the company manufactured electric synchronous clocks, among other products. In 1975, it continued operating under the name NEDKLOK-NUFA.
