I'm curious if anyone has tried one of the newer e-ink smart watches you see on Alibaba, which use ESP-32 or other low-power SOCs. I saw one recently at a meet-up and the guy who was wearing claimed it was completely open-source and he could run whatever he wanted to on it. It did not have heartrate monitoring or anything other than clock on it, as far as I could tell.



The original was Watchy: https://watchy.sqfmi.com/

Not only can you run anything you want on it but it supports the Arduino IDE and Micropython. I assume all of the Alibaba ones are based off of Watchy.


I have one of this still in it's box unassembled.

I like the idea. But I've been wearing mechanical watches for about a decade now...


The biggest issue is the software. It's mostly abysmal. The best effort I've seen so far has been InfiniTime for the PineTime. It's very difficult without full-time employees working on improving things.


What did it look like? All the ones I've seen have been pretty ugly - plastic cases, etc.


It looked like exactly what you said. Plastic.
