#Whole Watch Pretty boring, looks just like every F-91W, apart from the binary time display. Top vertical segments are hours, bottom vertical segments are minutes, horizontal segments are there for locating the bits.

#Frame The wire sticking out of the bottom left hole is connected to Vcc. It has been used to power the watch during firmware development.

#Perfect fit Like magic, all components fit perfectly within the plastic frame. Little space has been wasted.

#Blank PCB I case you're curios, there it is:
