Abstract: An analog universal watch has an area dial 4 showing different areas of the world attached to an area dial spindle 10 and an area dial wheel 11 linked to a timepiece drive mechanism through a minute wheel 15. A pawl fastened to an hour wheel 17 engages with a ratchet wheel 12 fastened to the area dial spindle 10 so that an hour hand spindle 16 is driven indirectly. Provisions are made to permit correcting the area dial spindle 10 by means of a hand setting stem through the minute wheel 15, along with the independent correction of the hour wheel 17 by means of the hour hand correcting wheel 25 that engages with and releases the hand setting stem. Thus, the timepiece permits not only the ordinary correction of the pointers but also the setting of the hour hand alone to the local time of the desired area.

Abstract: A clock, a calendar, and a two dimensional model of the earth viewed looking at the polar axis as the earth is rotated during a twenty-four hour period thus showing day and night, dawn and dusk. The shadow cast on the earth by the absence of the sun's rays are also shown. The changing of said shadow to show the seasons of the year is also shown as the shadow is rotated once every 365 days. The disc containing the rotating shadow has a pointer that tells the observer the month of the year and the day of the month along with the sign of the zodiac. The rotating earth map has symbols to represent the major cities of the earth and a symbol to represent the pole.

Abstract: A universal world clock (10) for indicating universal standard and fast time at any geographical location in the world. A south polar projected world map superimposed onto a manually rotatable map disk (14) is divided with twenty-four time zone indicator lines (20) representing the time zones of universal time, the map disk (14) being positioned such that the user's geographic location is vertically oriented to represent map north, and the map disk (14) being further positioned so that the time zone indicator lines (20) are aligned with time zone pointers (22) located on a separate zone pointer disk (16) which is fixed in position over the map disk (14). A time disk (18) having hour indicators differentiated by a.m. and p.m.

Abstract: Disclosed is a world time clock, which has an hour plate designed to rotate at a constant speed of 24 hours for one turn. The hour plate is printed with the official name of world important countries according to world time zone classification so that every local time is shown while the hour plate is carried to rotate on a fixed plate which has graduations for indication of hour, minute and second. As an alternate form of the present invention, an hour plate is printed or engraved with graduations to match with a face plate, which is printed with the official name of world important countries according to world time zone classification, for world time indication.

Abstract: A recorder of multiple events and durations of time, using one or more rotatably mounted dials graduated in a clockwise direction, with a means for displaying temporary memoranda which describe events associated with the said graduations, and used for directly recording and reading the actual or simulated times of one or more events either in absolute time or relative to the current time.
