Swarovski has joined hands with wearable startup Misfit to create the world's first solar-powered fitness and sleep tracker, says a report.

The solar-powered fitness and sleep tracker was launched at the Consumer Electronics Show (CES) 2015 in Las Vegas. The trackers come with a clear or violet crystal face, however only the violet crystal offers solar harvesting capabilities. The Swarovski fitness and sleep tracker can also be worn as a necklace. A full charge lasts for a few days and can be obtained with around 10-15 minutes of sun exposure, adds a report.

The report further adds that the Swarovski shine collection features a crystal face and comes with a self-charging battery that never needs replacing. The crystal is both functional as well as decorative, focussing light in a concentrated beam onto a solar cell beneath. The Shine Collection will be sold in starter kits ranging in price from $170 (£112) to $250, with nine additional accessories costing between $70 and $150.
