The Tone Wall Clock by Huygens combines the highest quality materials to deliver an incredibly accurate timepiece that moves in silence. A glossy transparent spot varnish is printed on the matte dial to create a ton-sur-ton effect. Depending on the light, the index print is clearly visible, slightly visible or not even visible at all, giving the Tone a contemporary edge. Place in the office, bedroom, or a place where time is relevant. Available in three sizes. NOTE: Requires 1 x AA battery
