These new models incorporate Neon Illuminator. A black light LED illuminates special luminous ink on hour markers, the hour and minute hands, and on the dial. The Roman numeral hour markers are arranged in two different layers, while the 12 and 6 o'clock markers are located on the inside of the glass. The result is four layers that make this watch as attractive as a bangle or other fashion accessory. Gloss white resin band analog and digital watch with metallic silver face.
