Misfit and Swarovski have teamed-up to create Swarovski Shine, an exclusive collection of two new wearable products and nine accessories, developed and designed by the companies for 2015. The Swarovski Shine Collection adds a touch of modern-tech to Swarovski’s signature crystal, adding the benefits of Misfit’s wireless activity and sleep tracking technology to the popular accessory brand.

The collection adds two new, fully waterproof wearables; a clear Swarovski Shine with a brilliant crystal face and a violet Swarovski Shine which uses a patented “energy crystal” technology to allow for efficient solar charging on a small surface to power itself. The latter is the world’s first wireless activity and sleep tracker that utilizes an energy harvesting technology to eliminate need for charging or replaceable batteries. Users simply expose Swarovski Shine to light to keep it charged.

Both designs feature a large faceted crystal integrated into Misfit’s hardware, and automatically track steps, distance, calories burned, and sleep quality and duration.

“Shine is the first truly fashion forward activity tracker, and Swarovski leads the way in the fashion jewelry and accessories market globally. This collaboration pushes the envelope as to how beautiful technology can be,” said wearables designer and author of Fashioning Tech, Syuzi Pakhchyan.

The Collection is now available for pre-order in the US exclusively on misfit.com, and will be for sale this spring in Swarovski retail locations in the US, Hong Kong, and China and on Swarovski.com.
