This is the clock with phosphorescent numbers that appear to float in mid-air. Providing an illusory holographic visual effect when seen in the dark, the numbers for 12-, 3-, and 9-o’clock are offset from the clock’s face with 11/4" posts while the 2-, 4-, 6-, 8-, and 10-o’clock numbers are offset by 1" posts. The varying number heights assign to the clock’s face three-dimensional depth that makes an intriguing display—especially when the clock is viewed at an angle in the dark. Clock will glow for about two hours after a day of direct sunlight. Requires one AA battery. 12" H x 12" W x 2 3/4" D. (2 1/4 lbs.)
