Flip clock (original) (raw)

A flip clock (also known as a "flap clock") is an electromechanical, digital time keeping device with the time indicated by numbers that are sequentially revealed by a split-flap display. The study, collection and repair of flip clocks is termed horopalettology (from horology - the study and measurement of time and palette - and the Italian "orologio a palette" - Italian for "flip clock"). People interested in the collection, restoration, buying and selling of flip clocks are known as horopalettologists.
