The colors of the rainbow watch face.
A minimalist watch face showing the current time with changing colors of indexes and hands, also displays the current phase of the moon. The dial pattern can be changed for Wear OS.
By clicking around 1, 3, 6, 9, 11 o'clock (as shown in the picture), you can start any application you set.
There is a widget available in the phone application.
(Note: If Google Play says "Incompatible device", open the link in the search engine on your computer or mobile phone and install the watch face from there.)
Have fun ;)
