Martini Cocktail Clock Martini Cocktail Clock It's never last call and it's always happy hour with our devastatingly hip Cocktail Clock. Shaped like a jaunty cocktail glass, this 11-1/2" (29.2 cm) tall clock has no numbers  a sure sign of chic sophistication. The second hand looks like it's stuck into a pimento-stuffed green olive and the pendulum is the delicate stem of the martini glass. Made of thin plastic. Requires one AA battery (included).
