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.
