ABSTRACT:
A radio controllable clock includes an analog display having a plurality of clock hands each fastened to a uniquely associated one of a plurality of clock hand shafts that each rotate about a common axis. The clock also includes a plurality of rotary gears each uniquely associated with one of the clock hand shafts, for rotating the clock hand shafts. Each rotary gear has a face perpendicular to the common axis, wherein each of the rotary gears includes a protrusion extending substantially perpendicular from the face. A microcontroller provides a plurality of drive command signals and the rotary gears are driven responsive to the drive command signals. A reset claw is operably positioned to engage at least one of the protrusions to stop the rotation of the clock hand shaft associated with the protrusion in order to position the clock hand associated with the protrusion at a datum position.
