This is a digital clock that uses the Xiao ESP32-C3 board from Seeed Studio along with their round display. No soldering is required and Arduino sketches are included, along with intructions on how to set everything up. 3x M2x8mm bolts and 3x M2x16 bolts are required for assembly and a USB C cable with either a 90 degree plug or a cable plus a 90 degree adaptor.

4 variants of the sketch are included. There is a light theme and a dark theme, and a second version of each which does not have the animated seconds dot. The sketches can also be edited to change the colours by editing the RGB values in colours section near the start of the sketch. (The section is commented to indicate it.)

The board and screen are available in many vendors but I found the best prices were on Aliexpress, the board being around £6 and the screen around £20:
