What is a 400 day anniversary clock?
A 400 day clock, also known as an anniversary clock, is a clock that uses a torsion pendulum mechanism to keep the time. A precisely weighted wheel turns around the base of the clock, like a pendulum that turns, rather than swings. This clock is called a 400 day anniversary clock, because it is said to go 400 days without winding, or can simply be wound on an anniversary, once a year.
