Both quartz and Eco-Drive movements provide highly-reliable timekeeping. The advantage of a watch equipped with an Eco-Drive movement is that it doesn't need the battery replacement. The watch gets charged from any natural or artificial light absorbed through the crystal and dial. The energy is stored in a permanently rechargeable lithium-ion battery that keeps the timepiece running forever.

The revolutionary Eco-Drive technology has the energy cell that stores enough energy to power the timepiece for up to an 5 years even in the dark. It depends on the model.

As for a watch with a quartz movement, usually you need to have the battery replaced once in 2-3 years.
