Hi, I was told that the Bangle.js 2 is based on the SMA Q3 (nRF52840), but I can't find it to buy a unit. I have also seen that there are very similar watches, almost identical like the Mafa MX7.
I found ads on Alibaba, but the minimum purchase was almost 200€. On AliExpress I found only one ad, but far from 20-50$, it costs 74,32€ (a lot for me, especially considering that it is a Chinese watch and that it is not 100% sure that I will be able to install the Bangle.js 2 firmware):

I've seen this website you sent me, but no those watches don't have many apps (what interests me most about the Bangle.js 2 are the apps):

There are also many other nrf52 watches that can run Espruino but need some tweaking so if you are low on budget and don't care for specific watch (Bangle 1 is very different from Bangle 2 in almost every aspect) and are not afraid of hacking/customizing it yourself you have many choices (in $20-$50 range, sometimes even lower). OTOH what real Bangle gives you is supported watch that works out of box, for that there is no substitute.
I do have few such spare unused hackable watches (including one F18 which is same HW as Bangle 1), send me PM for details if you are interested.
See e.g. what jeffmer has here https://jeffmer.github.io/WatchApps/ and there are few more available. Also some nrf52 fitness trackers can run Espruino as a minimalistic variant (price and size).
