Soon everything will be solar-powered, now it's a matter of refining the designs so that it's easy on the eyes -- just like the Sol Watch is.
Designed by Shin Azumi, the Sol Watch is more specifically a hybrid watch that features solar panels that extend the battery life by 50%. Currently part of the MoMA collection, it is being sold for $100 ($90 for members).
