Binary pocketwatch

i'm new here and was wondering if anyone knows how to make a binary poketwatch.
Like this only binary.

I've been interested in building a binary clock, as well, and found this tutorial to be very simple -

You'd have to scale it down some to fit in a pocketwatch, though. I'd say smaller LEDs will be the first downgrade.
If you do a search for "binary clock", there are several different setups you can use, but you should probably use a microcontroller based one so it will fit in the case, and integrate a switch to turn off the display so it doesn't eat batteries. You should be ably to run it off a 3V battery.
