This is done either by a press on the button at the top right - a quick(!) double tap - or by rapidly moving the watch upwards and rotating it towards you.

I have described this in detail in another blog post: Lilygo TTGO T-Watch 2020: Getting Started / The Software Framework.
#BACK TO THE FUTURE SPEEDOMETER INSTALL#
The very first step is to install and set up the Arduino IDE. This watch will just be fun to look at, and without WiFi and Bluetooth, but with a good power management, the watch will be able to run three or four days without charging. This watch is not a smart watch! It does neither use the Wifi nor Bluetooth connectivity of the watch (I wouldn't know what I would use this for anyway). Being a fan of the "Back to the Future" trilogy, in which the topic of "time" is omnipresent, I decided to make a Back-to-the-Future fun watch - and to share this. So, I decided to make my own, and share this. But then, I started to search the web for great watch faces for the T_Watch and I did not find much. When I bought mine in December 2020, I thought I was already late to the party. A programmable watch with reasonably small size (looking somehow like the Apple watch), based on the ESP32 processor with an accelerometer, plus Wifi and Bluetooth connectivity at a price of only $30-$40. The LilyGo T-Watch 2020 hit the market in May 2020.
