Ice-Watch ICE Solar Power Unisex Wristwatch with Silicone Strap - Medium Size Solar-Powered Watch for Men & Women - Perfect for Outdoor Activities, Sports & Everyday Wear

Solar powered Ice watches are great. I have collected several by now. They are just as accurate as traditional battery powered quartz watches, except they don’t use planet-killing batteries! They last many months on just nine or 10 hours of charging under a strong light. In addition to all this, they look really cool and they come in a very wide variety of patters and colors!
