The CITIZEN name was established in 1930 when the Citizen Watch Company began producing its world-famous timepieces. Over the following decades, Citizen applied the precision production technologies developed through watch manufacturing to provide a wide range of electronic components and products. This vertical integration has led to the development of advanced production equipment. Among these are the highly precise, highly versatile Swiss-type turning centers known in the trade as CINCOM (Citizen Numerically Controlled Machines) and MIYANO high precision, fixed head automatic lathes.
