If you are into tracking just the number of steps you take a day to logging your entire workout, you probably have a digital watch that does it for you. But you’d also need to charge it very often. Especially if you have GPS turned on or your playing music straight from the device.

And let’s face it. Some of us hate the fact we have to charge our devices every day when we get home. Adding a smart/sports watch to the list of tools we have to charge is a pain. But what if you never had to charge the device.

This isn’t the first iteration of the device. Back in 2017, it’s Indiegogo campaign to make the Matrix PowerWatch a reality raised $1.6 million. Matrix Industries followed this up with PowerWatch X at CES 2018. Both were only powered by body heat and feature a power meter which the device prominently displayed as a ring around the watch. Showing the user how much electrical power you are generating and how much juice is left.

The first device was expensive and had only limited fitness tracking features and no support for smartphone notifications. The second iteration of the device fixed the smartphone notification issue and was more rugged.

This time around the device runs both on thermoelectric and solar cell technology, meaining it is powered by body heat and ambient light. This latest iteration has built-in GPS, a heart rate sensor, compass, and a full-color LCD. Giving the user detailed running data including splits, pace, cadence, heart rate zones and a map of your route. And it is good to a depth of 20 bar. The acompanying app is also benefiting from a refresh, and there is integration with Apple HealthKit and Google Fit.

It measures 47mm in diameter, has a depth of 16mm and weighs 70 grams. The device is currently available for pre-order on Indiegogo for $199, a sizable discount on the $499 it will sell for once it’s officially launched in Q2 2019.
