Yesterday my watchy arrived and it took me 13 straight hours to get it to work. I followed the official documentation but neither ArduinoIDE nor PlatformIO seemed to do the job as I was constantly hit with a huge list of errors, no matter what variables I optimized. When I was pretty close to just surrender and send the watch back, the user GuruSR#6043 (much love) on discord let me know that I should try to update the firmware via ArduinoIDE BUT to change the upload speed to 115200 and to do all that on a laptop instead of my PC as there can be voltage spiking issues with the CP210x when using a PC.
I would love to have that info in the docs and maybe that is a thing that can be changed in future models. As seen here you already switched from DS3232 RTC chips to PCF8563, so maybe there is an alternative to the CP210x that also works on PC.
