Not Just Wrists: The New Look of Fitness Gadgets

This wrist-bound jewelry is Netatmo's June, which has a diamond-like jewel that actually monitors the sun's rays. It's meant to be worn as a bracelet or a brooch and estimates how much time the wearer should be spending in the sun according to data like skin type.

Every day, the app provides a summary of time spent in the sun and when UV rays were at their peak. It'll cost $99 when it hits stores later this year.
