Judging by your "overview", I am convinced that my preferences are different to yours.David.
LOL 
Having seen the face of that clock you're building, I think you should go for some retro / creative font.
Something like numbers 4 or 7.
But i'm not sure how well one could read that.
Like David, i wouldn't use such fonts myself but that doesn't matter.
It's your project.
You've already drawn your characters, can't you pick a few and test them in the almost ready product ?
Shouln't be too hard to change fonts.
