Every part of this watch face is "handcrafted". It uses only OpenGL and the base Android system. Every part of the face is programatically rendered, except for the fonts, which are drawn by the superb LibreCAD software on the outstanding Fedora OS.It is OLED/AMOLED display friendly. On these displays the blue component wears out fastest. This watch face doesn't use any blue component.
In Ambient mode it periodically switches between filled and outlined font rendering, it aims to reduce the burn-in effect.
It is optimized for 320x320 display resolution, it should scale up well to 400x400 and scale down well till 256x256.
It is currently tested on ASUS ZenWatch 2 (the bigger version). Early beta versions are reported to work on other watches too (see photos).
