The hours never looked more chic - thank you, Seiko Black Wall Clock - 12.25 in. diam. With a streamlined, versatile modern design, this wall clock features a black-finished plastic case - an elegant contrast to the hands, numerals, and markers, which all illuminate in the dark. You’ll also find 24-hour markers along the inside of the dial for military time, and the quiet-sweep second hand eliminates loud ticking. One AA battery is required.
