Can you tell me guys if there are tower clock design out there that uses only two wheels? If none then do you think I am the first to design this kind of clock movement? In my next project I am going to build a clock movement with hour wheel and the center wheel only as the active components. They are driven by two separate motors that are being controlled digitally. I was inspired of the quartz watch that came out of the market long time ago named Casio. It has an analog display but the entire display was LCD. The hands run at stepping motion and that the minute hand has more bigger steps than hour hand that has smaller and fewer steps. Any comments?
