CITIZEN WATCH Co. "...in 1976, we created the world’s first light-powered watch. The technology was named Eco-Drive."

"Eco-Drive converts any kind of light into energy to power a watch, storing the surplus on a power cell. On a full charge, an Eco-Drive watch runs for months even in darkness with no need for regular battery replacement. It’s designed to charge from ordinary everyday light sources like indoor fluorescent lighting and desk lights. You can go about your everyday life confident that your watch will never stop."

We prefer to shoot photographs outside when weather is permitting. However, when we shoot indoors, please be aware that we shoot our photographs inside of lightboxes that are lit with 360 LED bulbs. This indeed magnifies any flaws. Usually, they are much less obvious to the naked eye. Having said that, we never photoshop any of our photography, remove blemishes, etc. We adjust the lighting, when necessary, but what you see is what you are getting, and we take pride in that. 

The condition is pre-owned. 
The item may have some signs of cosmetic wear but is fully operational and functions as intended. 
Please review the photos and feel free to ask any questions you may have.  

It will be carefully packed.
