Overview of photodynamic energy watches, English is Ecology-Drive, is a built-in system to convert light energy to electrical watches. Due to the use of batteries that do not have to be discarded, it can save a limited amount of earth resources and reduce pollution, making it a truly eco-friendly product. In 1996 in Japan made the watch industry's first "eco-product mark" that. In 2001 won the Chinese watch industry's first "environmental labeling products" certification. Not only to achieve the "light driven watch", but also, rechargeable batteries are no longer used mercury, cadmium and other harmful metals. Moreover, the manufacture of the product material also avoids the use of other harmful substances such as fluorine, and has passed various stringent standards that convert solar energy into electricity through solar wafer and live in reusable titanium-lithium-ion rechargeable batteries. The energy generated by the battery through the integrated circuit to generate pulse signals to the coil and magnetic drive stepper motor to promote gear rotation and drive the pointer to indicate the time, fully charged can run 40-180 days in the dark, accurate travel time, rechargeable batteries Life expectancy up to 10 years. At present, the more energetic watches made of light watches are mainly Citizen, Casio. Light kinetic energy watch superiority: 1. Can use any light source to drive the watch to run 2. After ample energy, even in the dark can still run 1-6 months 3. With insufficient storage battery warning function 4. With school warning function 5. With to prevent overcharging 6. No need to replace the battery
