From the sizes, the Powerwatch X is bigger, perhaps a bit bulky, but the 51mm case size suggests a watch that’s definitely not for smaller wrists, while the 47mm case sizes of the other two could be adjourned moderate and certainly will look great on more wrists compared to the 51mm case size.

Matrix Powerwatch smartwatches are quite exceptional for being thermoelectric powered. These watches use your body heat to remain active. Very exceptional, I must say.

However, while the Powerwatch and Powerwatch X are thermoelectric powered, the Powerwatch 2 takes it further, featuring the thermoelectric capabilities and as well is solar powered. Meaning if it’s not on your wrist, you can still charge it up by exposing it to sunlight.
