12 volt clock.

I replaced my factory CD player with an alpine which has a clock feature but I have to press a button to use it. I am looking for a 12 volt clock that I can install into the plastic area around my map lights. Or put it in the plastic surround above my CD player.

Any suggestions? The reason I think doing it near the map lights would be in case I messed up the cut this piece will be cheaper to replace.
I have yet to find a quality clock that will look good.
