Equation of Time
An ‘equation of time’ watch shows the difference between ‘true’ solar time (that of Nature) and ‘mean' solar time (that of Man). It is a representation of our physical world that closely ties the watch to the sun's cycle to get to the heart of how we keep track of time. It is commonly supplemented with other astronomical signs.
