While looking for arduino-based hardware to move my LED watch prototype to, I stumbled on the times square watch. Not merely perfect, but better than anything expected to find!
Already on order.
However, I have two questions:
Can any of the LCD matrix parts you sell reasonably be used in place of the one in the kit? In particular, the bicolor one would allow me to build the watch whose prototype is running on my desk now. I don't expect that to work, but it would be great if it did.
Second, is there some way to develop faces on an arduino other than the watch? Running the Watch library (possibly hacked) on a Uno with a compatible (which means?) LCD and RTC?
