Quartz Watch Movements

Automated assembly lines in the clean room

In the manufacturing process of analog quartz watch movements, we make full use of equipment such as high-speed pressing machines that can process large quantities at once and injection molding machines that can freely process both metals and plastics. These are dedicated devices that are adjusted independently and can mass-produce parts with high efficiency and high precision. This allows us to manufacture even very small, complex parts in-house. In the assembly process within the clean room, watch movements are assembled by robots with advanced programs that carry out the various operations, including assembly of each part (mounting of ICs, coil blocks, quartz crystals, etc.), accuracy adjustment, and inspection (vision system). The combination of manufacturing know-how, cultivated since the company’s founding, with the latest technology such as robots enables us to achieve both precision and productivity.
