I have a round analog clock with a particularly strange arrangement: it has a second hand (that ticks every second), and it has a minute hand that only moves every fifteen seconds.
(It's a radio-controlled clock: it has the second and minute hand on separate motors presumably because syncing to the actual time if there were only a motor for the second hand like a conventional analog clock would take too long (and probably make determining position more complicated). There is no independent motor for the hour hand, so it does have to roll the minute hand around to move that one.)
