. I've got the touchscreen working 100%
Nice! Is it the magic board, or a new one? Is the touch the auto sleeping type? Is the screen brightness more magic3 like or rock like? :)

Not Magic/Rock board, it's totally different, different pins all around. (https://github.com/yngv27/EWatches/tree/main/TK87G).
Screen is ST7789 240x280, very nice, I'd say it was Rock like. Don't know if touch is auto-sleep, I just put it to sleep on screen sleep (I adopted @jeffmer 's wOS object). It's light weight, like the (ironically named) Rock, much lighter than the Magic3.

I've kept my work on other watches relatively quiet, as I didn't want to steer anyone away from supporting Gordon monetarily. I think everyone should buy some kind of Espruino hardware to keep the proverbial lights on.
I feel fortunate to have learned enough from folks here HOW to build Espruino for various watches (all nRF52), and for me, the fun is in the discovery of the hardware internals. Like @fanoush I don't wear any of these hacks.
But since much of the cat has left the bag....
I'm working with two others right now:
P4: https://www.aliexpress.com/item/1005007150275911.html - 52832, but DaFit so hackable without opening. It seems to be having power issues (likely needs some pin pulled up/down - not sure). Classic DaFit: shared SPI for LCD and Flash, for which I use @jeffmer 's build to manage. This is something neither Bangle had to contend with, so it was the efforts of folks here who made that happen.
TK78G: https://www.aliexpress.com/item/1005008054139256.html (and above from @enaon )
52840 with tons of goodies like GPS, temperature, HRS, accel, two buttons and touchscreen. I've got the touchscreen working 100%, accelerometer usable (don't know what it is, so not sure what options I can set like changing sensitivity/power settings). I have been trying to figure out the GPS, as I know what pins are being used, but I can seem to turn it on. But if you want to explore, and learn, this is a good one to work with!
And as mentioned above: Pinetime (https://pine64.com/product/pinetime-smartwatch-sealed/) very similar to P8 and very well documented. New ones arrived sealed, which makes things a bit more tricky.. it takes a bit of effort to put the correct bootloader on this for updating to Espruino.
But the only way you'll get a full support watch is Bangle2. Everything else is "roll up your sleeves", and quite a bit of swearing.
