Each number is made of a 2-dice roll.
The dots are printed as small holes on the dice, and I've used a permanent marker to bold the ones showing the numbers. It didn't come out as nice as I thought but it is still a nice design (IMHO). Some of the dice look as if they are about to fall from the body.
The body has a hole to attach a clock mechanism to it, but I had to cut the dial hands a bit.
I've attached the Fusion360 export, there you can play with the model (for example, you can change the basic cube and it will effect all the dice in the clock).
