The mechanical anniversary clock, also known as the 400-day clock or torsion pendulum clock, is one of the most popular clocks ever invented. Anniversary clocks are recognizable by the decorative balls beneath the dial that rotate one way and then the other.

Called the anniversary clock because it needed winding only once a year, it has carried on into the days of no winding at all.
