What is the difference between quartz, kinetic and solar powered watches?
We often get asked for Kinetic, Eco-Drive or Solar watch ‘batteries’, so we thought it might be helpful to provide a little information about the different types of watches we specialise in repairing.
Quartz
Quartz watches work by utilizing the natural quartz crystal's piezoelectric properties.
A small piece of quartz crystal inside the watch vibrates at a precise frequency when an electric current is passed through it. This frequency is incredibly stable, which allows for highly accurate timekeeping. The vibrations are transmitted through a series of gears and levers, which move the hands on the watch face.
They are powered by a small battery that typically lasts for years before needing replacement.
Kinetic
Kinetic watches don't use traditional batteries or manual winding to stay powered.
They use the energy generated from the natural movement of the wearer's wrist and arm to keep accurate time. Inside the watch, there is a rotor that spins as the watch is worn, generating energy that is then transferred to a capacitor. The capacitor stores the energy and powers the watch's quartz movement, ensuring precise timekeeping.
Some kinetic watches feature energy storage indicators that show how much power is left in the capacitor.
Solar & Eco-Drive
Solar and Citizen Eco-Drive watches use small photovoltaic cells, built into the face, to convert light energy into electrical energy that is used to power the watch. The watch's solar cells absorb both natural and artificial light and convert it into electrical energy that is stored in a rechargeable battery. As long as the watch is exposed to light, it will continue to recharge and run.
The recharging efficiency of a rechargeable battery may gradually deteriorate for various reasons, including long-term use. In this case, we can supply a new rechargeable battery.
