Perspective is a truly unique time piece, guaranteed to turn heads! Literally! At noon, 12oclock is straight up and at midnight, 12oclock is straight down. So I guess that’s how it displays AM and PM. The face rotates to the left while the hands rotate to the right. The face is 20” diameter so it doesn’t look puny on a large wall. This apparatus runs well on 7 pounds. It will run over 24 hours depending on height. The face is driven via the dial train like the hands so setting it is no extra hassle. It is a consistent running clock. You will enjoy having this time piece on the wall!
