O Watch is an open source Arduino based smart watch kit designed for kids to create their own watch and learn the basics of coding, 3D design, and band making.

3D Printing: O Watch cases can be customized and 3D printed at home, a makerspace near you or via online 3D printing services. Sample 3D design files are freely available to download and customize.

Coding: Arduino is a very popular open source hardware platform for all ages to get started with coding. O Watch is based on the Arduino Zero platform and is programmed using the standard Arduino IDE.

Band Crafting: The watch bands can be made at home using several band making crafts like paracord bands and rainbow loom bands.
