PURPOSE: A method for expressing time by using a variable area through color is provided to enable a user to easily grasp time by using the variable area of a clock plate with two colors. CONSTITUTION: A time display(11) is formed around a first disk(10). A slot(12) is formed on a position facing 12 o'clock from the center of the first disk. A cut part(21) is formed in the center of a second dick toward 12 o'clock. The second disk is overlapped under the first disk. The first disk is fixed and the second disk is rotated clockwise. The second disk passes through the slot of the first disk base on the cut part and goes up the first disk. |
