My first creation!
The logo of the Batman TV series from the 60s (with Adam West as Batman) for those who love retro style.
The hands are simple triangles, hour + minute in blue, seconds in red.
Pulse (average) corner top left, top right outside temperature.
Lower left corner battery in %, bottom right the day (no month).

EDIT: version 2 with changed (lighter) blue for pointers for better contrast.
