The Seiko C359-5019 watch movement is characterized by its main plate and bridge construction that is made of brass with a gold coating. The movement features an oscillating weight made of heavy metal, equipped with a ball bearing known as the ETA ROTOR. It includes an automatic recharging mechanism that is integrated into the basic movement, as well as classic ETA type pawl winding wheels. The movement is driven by a stepping motor that produces 1 impulse per second. The movement is pictured from the dial side.
