The workflow is basically: weights → escapement → minute driver &rarr 1/60th reduction. Both the minute hand and 1/60th reduction output to the face. The weights will probably follow a design similar to the knex escapement - the string will be wound around a larger coil to reduce variation in the power output. The weights will use a multiple-pulley system to leverage their limited drop distance. The output will go through at least one reduction before being regulated by the escapement. | |||

The gearing is made fairly easy by the gears provided by Lego. I've built some demos, but need to start making some actual prototypes and start putting everything together.
Escapements:
