Improvements in watches, which are characterized by providing them with a rotating sphere in unison with the transparent hour wheel at least in part and a lamp located behind said dial, allowing the projection of part of the representative numbers of hours and hours. Other representative signs of the hours and other representative signs of hourly fractions, against a screen, which may be the wall or the ceiling of a room, while a needle or other fixed reference is arranged on a transparent part in proximity to the part of a transparent sphere that is projected, thus projecting its shadow adjacent to the time projected against the screen.
