Seiko Clean Energy Watches

With clean energy watches, the Japanese watch manufacturer Seiko shows respect for the environment and makes watches run with no battery change ever needed. The Seiko Solar, for example, takes its energy only from light and saves it in a recharging battery in the inner of the quartz watch. With the first Solar watch being developed in 1977, Seiko counts to the earliest pioneers in solar watch technology. The solar cells are invisibly integrated in the watch’s dial. In fact, the only indication that the watch is working with the power of light is the word “Solar” on the dial, otherwise the dials are truly the color you chose, like really white, black or blue.

 

Even though Seiko Solar watches work best with sun light, they also work with fluorescent light and charge very quickly. For most watches, one minute of sun light is enough to deliver one hour of charge, after three hours of incidence of light the watch usually is fully charged and would even retain its charge during 6 months of total blackness.  

Other examples for Seiko Clean Energy Watches are the Seiko Mechanical, the Seiko Kinetic and the Seiko Spring Drive.
