The Shadowline is a black arched glass alarm clock, 6 inches tall, with tapered sides, satin silver accent stripes, brushed aluminum base plates, and a polished silver-tone bezel. The white dial carries black Roman numerals and luminous hour and minute hands for reading in the dark, and the quiet sweep second hand means no ticking beside the bed. A felt bottom protects the surface it sits on. Quartz alarm movement, powered by one AA battery.
