Exemplary arrangements relate to a universal world timepiece such as a clock having a movement (11) in connection with indicators such as hands (16, 18, 20). The timepiece includes a stationary oriented 24-hour clock face (101, 301, 401, 501) including hour marks for each hour, and a dial (103, 303, 403, 503) which is movable relative to the 24-hour clock face. The example dial has a unique icon such as a different Latin letter for each hour of the 24 hours. A computer (10) of the timepiece may operate to determine geographic coordinates and/or or to receive wireless time signals and to determine the time zone in which the timepiece is currently located. The computer operates to cause the dial to be rotatably positioned responsive to the time zone determination, to cause a particular icon to be linearly aligned with a particular hour mark of the clock face. The arrangement enables a time in a designated time zone such as world time to be read, along with the local time and enables users in various time zones with clocks including such dials to set a future appointment at the same real time through designation of an icon.
