Ever get frustrated in the winter when you want to check the time and your watch is buried under multiple layers of long-sleeves? Deisgner Mac Funamizu of Petitinvention did, and came up with the Clip Watch concept–a watch designed to look like a button and powered by the sun.
The Clip Watch attaches easily to your outer-wear and is designed to look like nothing more than a button (albeit a rather strange one, such as a Secret Service agent might wear.) Yanko Design reports that all you need to do to check the time is click the face once; you’ll get the date and time on the glass face for a few seconds before the device reverts to it’s strange little button-like face.
The device makes use of a battery that gets topped off periodically by solar energy–a design that takes into account the fact that sunny days in the winter tend to be few and far between, if you live in a climate cold enough to make your wristwatch inaccessible in the great outdoors.
