Today’s invention is a clock with no central mechanism.
Instead, the hands would each be located on a central axle, but be propelled by a small car at the distal end, driving in a circle at a speed of 1 revolution per hour or 12 hours.
These vehicles could be radio-controlled on eg a clock-tower face.
In the event of some malfunction, each vehicle could be replaced much more easily and cheaply than repairing elaborate clockwork.
