The Zaria 2009A watch movement, produced from 1959 to 1979 with an estimated production quantity of around 100,000, is based on the design of the Venus 150 movement. Its serial number of 00003 suggests an early production model. The setting-lever spring of the movement consists of four gaps for specific functions: 1) winding, 2) no function, 3) setting, and 4) inaccessible for the pin. The movement features a manual-wind chronograph with a 60-second and 45-minute recording capacity, operated by a pillar wheel mechanism. Additionally, it includes a sub-second display.
