README.md

People like photos, so I took some.

#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.

#Populated PCB Despite of the small-sized components (all passives are 0402), populating the pluto PCB is doable given a microscope and plenty of flux. The inductor at the bottom left as been harvested from the original PCB. The crystal is wrapped in sticky tape to avoid shorting C1.

#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:
