The Open-SmartWatch is an open source project created by "Paul's 3D Things". It consists of hardware modules, 3D printable cases, and a custom operating system to build smartwatches with the goal that they can be assembled, repaired, and modified by everyone.

It will include:
- Open- SmartWatch PCBA board
- 3D-printing Case
