It does not appear in the search engine, so here are a few notes on it.
What is it - an ESP32 with e-paper display in watch format. Silly price from PiHut.
I've not had success with e-paper and this appeared to work so I bought one.
It is a big lump of watch with stunning display and 4 tactile buttons. Comes with a watch strap but I had thought it might be more useful as an IOT terminal/controller.
The supplied and programmed software is the biggest lump of ESP code I have ever seen - It's a watch with battery monitor, pedometer, temp and weather which it gets via a menu to search and choose your WiFi router. It seems to take forever to compile and upload and I failed to get it to work under Arduino 1.8 so have to come to terms with Arduino 2 which works fine.
Regretfully it does not have GPS.
To get my head round the board I ripped apart the supplied software to leave just the menu system and the clock screen which I simplified to get to terms with the display. It now compiles quickly and uploads equally quickly. It runs about a week on it's tiny lithium cell.
Here it sits, amazing display, waiting for me to think of something to do with it,
This is actually pretty cool, although it's been decades since I wore a watch.
I just checked Mouser, but it's out of stock, same with Pi Hut. When it's back I might pick one up and play with it, I'm thinking that it might make a cool custom remote control for a robot or IoT app.
Thanks for pointing it out!

My pleasure, it really is a solid piece of kit with good switches and a useful battery life as controlled by their demo software that seems to do the compromise of sleep/awaken quickly, very well, the menu button is instant wake up.
The screen is unprotected but I've seen a link to buy one for about $2.00.
@hilldweller That is super cool! I'll have to check it out. I am currently working a project where I am trying to build one from scratch : https://forum.dronebotworkshop.com/esp32-esp8266/esp32-digital-watch-status/#post-41738
Keep me in the loop!

That is pretty amazing today, common when I was young, last century. When I've been trying to engage with my grand kids the problem is always whatever I could do is out there already ten or a hundred times better. Pressing a button and an LED lights up, even if the button is on a phone and the LED is across the room, it's nothing. Once Pacman was amazing, now kids expect full 3D rendering.
One area that does impress them, a little, is WS8212 LED strings, big and bold. This Watchy could well be remote controlling some this Christmas ( or, today, this end of the year holiday ).
That second video is a magnificent effort, very similar to Watchy but not a patch on the e-paper display which makes it usable, an OLED display will have such a limited battery life.
Good luck with your project.
@hilldweller I really love that watchy display. What library(s) are available for that? To be honest, battery life was one of the main drivers in my design. Even though an oled, I am pretty sure I can get 2 weeks between charges with a 600mAh battery. However, I think with that epaper display....mamacita!
@fishbone What library(s) are available for that?
I used the huge 7_SEG sketch that was on the watch as standard, then simplified it to get my head round it.
I have now lost track of when I last charged it, it's been showing battery empty for a week and I guess about a week before that showing decreasing battery. With the e-paper I can just wait 'till the time stops updating, then it's flat.
It happened today - screen stopped updating. That's a very long battery life.
The downside. I put it on charge and it then displayed bad date and time.
I reset the time and date and it showed the correct time and date with a shadow of the setting screen, so on minimal voltage the screen cannot update fully. However an hour later all is back to normal with a "clean" display.
At least I now have a logged charge time/date.
