Mandom

Unlike most stands, Mandom has a physical manifestation rather than a psychic one. It's physical manifestation is it's users (Ringo Roadagain) wrist watch. By turning the hand on the wrist watch, Mandom can rewind time by exactly six seconds. Ringo stated this himself when he was describing Mandom's ability: "not a second more, not a second less". Those in his presence seem to be the only ones aware a time reversal has taken place. A fact exploited by Gyro when he constructed a plan to defeat Ringo using a piece of wood he saw before Ringo used Mandom's ability to turn back time.
