PhobiClock v.1 - A norwegian TwoClock clone

I really loved the TwoClock design and idea, and I wanted one. But it is to expensive, and I though, how difficult would it be to make my own?

The lettered front is lasercut at work on a two-layer (black on white) sign, so I unfortunately don't have anything to share here.
