Global clock

A round-the-world watch comprises a watchcase, a watch dial and a transmission mechanism. The utility model is characterized in that the watch dial is driven to rotate by the transmission mechanism, the watch dial rotates for one circle in 24 hours, representative place names in all time zones of the world are marked in the circumferential direction of the watch dial according to the longitude positions of the earth, time scales from 1 to 24 are evenly marked in the circumferential direction of the watchcase, which is corresponding to the circumferential direction of the watch dial. The utility model has simple structure, and can reflect the time of all the time zones of the world visually and correctly, the rotating speed of the watch dial is the same as the rotation velocity of the earth, thereby the natural law of the diurnal variation of the earth can be visually represented, and the utility model is suitable for being used by people around the world.
