Gideon Dagans clock captures the essence of pure minimalist design. A seemingly gravity-defying ball travels around the dial to mark the time creating an eye-catching illusion. Based in California Dagan has designed numerous consumer and commercial products including hand-held computers and electronic instruments. His innovative designs have been recognized in many patents and awards both in the United States and abroad. The Timesphere Clock reflects the Museums long history of documenting and displaying timepieces from the modern era many examples of which are featured in the Museumâ€™s collection. Made of injection-molded ABS plastic the clock features a high-torque precision quartz movement. One AA battery is required (not included).
