Mantel Clocks. Mantel clocks are generally offered in one of two different types of movements: mechanical key-wound or quartz battery-operated. Arguably, the more sophisticated types are key-wound. These types of mechanical mantel clocks are powered by springs that slowly unwind as the clock runs. The springs will unwind and generally power the clock for up to seven days, at which time they need to be wound again by inserting a key into the holes of the dial.
Analemmatic sundials are a type of horizontal sundial that has a vertical gnomon and hour markers positioned in an elliptical pattern. There are no hour lines on the dial and the time of day is read on the ellipse. The gnomon is not fixed and must change position daily to accurately indicate time of day.
