The Eterna is a wood and glass alarm clock with a high-gloss white piano finish on the top, base, and rounded side columns, 7 inches tall. Its white dial carries black Roman numerals at 12, 3, 6, and 9 with square hour markers between, and luminous black hands for low light, behind a glass crystal and a polished silver-tone bezel. The sweep second hand is silent. A felt bottom protects the nightstand. Quartz alarm movement, powered by one AA battery.
