I have the T-Watch 2020 collecting dust on the shelf. Biggest downside is the battery which can't last a single day (and has to be charged through USB micro port with a flimsy plastic cap). The "speaker" and microphone are both very low quality. Other than that the hardware works as advertised. It's a complete ESP32 device in a very small form factor that could be repurposed as home automation interface. Software support is quite bad. The arduino examples are mostly useful to confirm the HW is working. The provided OS with UI and gestures is not robust or pretty. It's best to drop to the toolchain that espressif provides, and there are some repositories that make this easy. Last I saw, there's no good foundation to start writing "apps" on top off, you have to treat it as bare metal embedded system and start from scratch. This is where I shelved it, after about two weeks of board bring-up with MicroPython and C++.
