After looking for Lego designs, I found one for a Lego grandfather clock. This gave me the idea for to find an analog clock design, but there were none geared from only legos. So, after a few failed attempts, I made one myself and it works great. 
The first 6 pics are overhead shots and finished product.

the rest are photos of construction. 

Use Motor 71427 (output 360 rpm)!

you should try making one with concentric arms. i designed one a few years ago using a turntable for the hour hand.
