    Matrix PowerWatch 2: the smartwatch you do not need to load

    Matrix PowerWatch 2: the smartwatch you do not need to load

    This watch is powered by both the sun and the heat of the body. We tested this promise for the future.


    The Matrix PowerWatch 2 is manufactured by Matrix Industries, a Californian start-up specializing in thermoelectric that had released a first version that worked well but was not great. This new version is much more successful and finally approaches a watch everyday.

    We have it on the wrist non-stop for almost a week and the level of its battery has not dropped one iota. And if everything goes as planned, we will never need to recharge it.

    A connected watch is powered by solar energy and body heat

    It's still far from the best connected watch we've ever worn, but that's not the goal of its designers. It is first the fact that it never needs to be recharged which is the most amazing. The production of solar and thermal energy can be tracked graphically on the screen.

    The first Matrix watch could only follow the steps and give the time. The PowerWatch 2 features GPS fitness monitoring, notifications, step count, sleep tracking, calories consumed, and heart rate. After a week of use, everything is fine. We receive notifications with a haptic alert, but they are sometimes difficult to read on the color screen always on which is subject to reflection. The navigation is not tactile, it is done by side buttons. The PowerWatch 2 syncs with the Apple Health and Google Fit apps. For the rest, the data is basic: number of steps, calories consumed, sleep (which is not as detailed or as useful as Fitbit's Sleep Score app) and information on daily energy production.

    The choice of dials is not huge, but the default dial is clear and readable, especially in bright sunlight. You can see the number of steps, the heart rate (taken at intervals, not continuously) and start a workout, but the GPS signal is a bit slow to hang. Matrix suggests using GPS only 30 minutes a day before battery life begins to run out. A micro USB charging dongle is included in case the GPS will drain the battery faster than the PowerWatch can restore it.

    What disturbed us most is the fact that notifications do not always appear on the watch and result in a simple vibration.

    Navigation in the interface is not as intuitive as a touch screen. You have to juggle four buttons, which is not very practical. But for all that, we like to wear this watch. Its somewhat bulky design is not weird and it is totally usable everyday.
