If you're looking for something with an addressable LED matrix in a clock style form factor, the Ulanzi TC001 [0] for ~$50 is worth having a look at.
Doesn't quite have the same aesthetic but inside it's just an ESP32 (flashed via the USB-C port) and there's various mature open source firmware replacements. I use awtrix[1] on mine and it's very easy to tie in HomeAssistant for doorbell notifications and that sort of thing. I did also knock up a Pomodoro app for it.
