Jewelry, Eyewear and Watch Design Jupiter Watch by Dabi Robert Inside the Jupiter watch, steel spheres are rolling in hydraulically pressed channels, held in place by magnetic force. The wavelike dial is inset into the convex shaped crystal glass, which prevents the spheres from leaving their paths. A glass dome covering the top watch area transitions into the stainless steel casing seamlessly. With omission of a visible stem, watch hands or markings, there are no elements to distract from the time-telling spheres. Despite the absence of visible watch hands, a conventional quartz movement is being used to drive the planetary time indicator.
