The base of this sundial is a classical equatorial sundial, but the plate is movable by a mechanical system. This mechanism contains a manually rotatable dial. On the face of this dial inscribed a date scale, and a correction dial is fixed on its axle. The radius of the correction dial is fit to values of the analema curve in each points respect to sundial mounting location. If date dial is rotated to the actual date position the mechanism adjusted the plate position and the sundial indicates the correct mean time, not the solar time. The mechanism includes two switch. First of these switches between the local mean time and standard time, the second switches daylight sawing time. The Moon-phase display is driven by cog-wheels from the axis of the date dial.
The construction designed by Hungarian engineer Béla Kupás-Deák in 2004, created in the laboratories of the Budapest Tech, helped by senior armourer Lajos Nagy. The blazon of Budaörs is visible on the western side of the truss. The caption is “Anno Domini 2004. Budaörs”. On the eastern side the blazon of Hungary is visible with this caption: “Maria Regnum Marianum”. The cross on the top with stone is a miniature copy of the cross of Ko Hill locates nearby Budaörs. Inside of the truss readable a part of a Hungarian version of The First Epistle to the Corinthians from Paul of Tarsus (1 Corinthians 13).
The sundial has been erected in 2005 at the Templom square by local government of Budaörs.
