Special thanks to https://www.PCBWay.com for sponsoring this video. PCBWay provides fast and easy PCB prototyping, 3D printing, and CNC services. I made my own smartwatch from basic components, and created everything except the board and screen, including the case, additional hardware, and the operating system.
The main board used was the Lilygo T-Display S3 AMOLED (https://www.lilygo.cc/products/t-display-s3-amoled), and features an ESP32-S3 SoC that provides built in Wi-Fi, Bluetooth, I2C, and USB-C interface.
The case was designed in Google Sketchup, and the operating system (mPOS) and applications were written in Python using the Micropython firmware, and the main AMOLED board driver was provided by nspsck on GitHub.

3D model of case, but you'll never use it since it's for this specific board: https://drive.google.com/file/d/1o5BmoGZvYbOHexXvD-pDrrlnK1t4bjFu/view?usp=sharing
