World time clock face for directly showing the time in different countries of the world without needing to convert the local time where the user is

摘要

The clock or watch has a housing, a clockwork mechanism with three concentric rotatable finger axes and a clock face, a short finger and a longer finger and a calibration ring with 60 points to show minutes and seconds. A time zone ring surrounds the calibration ring. This is divided into fields corresponding to the 24 time zones of the earth and showing the names of countries in those zones. The clock face rotates with a 12 or 24 hour period and the hours are displayed in an anti-clockwise sense.
