Quartz ECO or KINETIC DRIVE ,Watches are a BAD IDEA !

ECO or KINETIC  DRIVE  QUARTZ WATCHES were heavily promoted as watches you would never need to buy a watch battery .and this is true up to a point because instead of batteries their power source whether it be Solar powered or by movement of an Auto Rotor the energy is instead stored in a CAPACITOR which is hard wired into the watches mechanism so is very expensive to replace and rarely has a life span longer than 12 years  the part will have to be specially ordered from the manufacture and may take several weeks to obtain . Normal QUARTZ watches depending on quality of the movement can have a watch battery last anything from 18 months to up to 36 months and normal can be changed while you wait and for a fraction of the cost of a replacement capacitor
