Is the light kinetic energy of Citizen better than that of Seiko?
Must be a citizen. Photokinetic energy is a citizen's patent. Seiko has only one solar energy at most, but it can't be compared with it, and it's not at the same level at all. Citizen optical dynamic watch is developed on the basis of Citizen quartz watch movement. The dial, integrated circuit and battery have been improved accordingly, and a solar chip has been added. Compared with quartz watches, Citizen optical dynamic watches have all the functions of quartz watches and unique functions of optical dynamic watches. You don't need to change the battery often, you can always follow the sunshine or the lights at home, which is very convenient.
