Hi Chaibill,
Quartz watches can be battery powered or cell powered. Eco-Drive recharge it's cell by light, while Kinetic recharges by mechanical movements. Some watches combine movement and solar to charge their cell.
To answer your question, depending on which Eco-Drive calibre, their accuracy varies. The Citizen E-510 Calibre used on the Eco-Drive Exceed series have an accuracy of 10s/year. I guess with a power reserve of 6 months, they must have some circuitry that compensates for it's accuracy.
