Citizen Analog BF2006-86A Quartz Men’s Watch

Citizen designed the first light-powered analog quartz watch that can generate electricity from just any light source – natural or artificial, bright or dim. It keeps the watch running forever and since there is no need to take the case back off to replace batteries, the factory seal stays intact for as long as you want. The watch represents an exceptional technological achievement that reflects concern for the preservation of ecological balance.
