A phenomenon where you look at wrist in order to check the time on your watch which you swore you put on before you left the house this morning and realize its not there. Can lead to ridicule if done in response to someone asking for the time and he/she realizes what just took place.
Guy1: "Dude do you have the time"
Guy2: "Yeah sure let me just check" *looks at wrist, realizes there's nothing there*
Guy2: "So...maybe I should ask someone else?"
Guy1: "Goddamn ghost watch...."
