Nice clock.
I guess you need a 10grams PCB to replace 100grams of wires if doing a final version.
Is there any documentation of this project and design in your blog, or elsewhere?

Unfortunately I can't find the schematic. It is very old as I said. All I can say is that... it consists of 4060, 4020, 4017, 4011. It is very easy circuit. So sorry I don't have time for reverse engineer ;-) I'm out.
