There have been attempts at making and selling source open source-friendly devices, from desktops to tablets to, of course, smartphones. There are even open source and privacy-oriented smart speakers. All that's missing is a smartwatch, one that's not just a smartwatch OS slapped in proprietary hardware. Rising to that challenge is Pine64, creators of a line of ARM-powered open source friendly computing products. While it says that PineTime smartwatch is just a side project, interest could catapult it to an actual product in the very near future.
