Abstract: The present invention discloses devices for projecting holographic content from a watch and methods therein. Devices include: a watch base for housing the watch; an opaque watch face attached to the base; a transparent watch cover for protecting the face; a light wand having a series of controllable light-emitting elements configured to project the holographic content, wherein the series is disposed on the wand such that light emitted from the elements is projected primarily toward the cover, the wand is disposed: mostly parallel to the surfaces of the face and cover; and between the face and cover with a spacing greater than about 40% of a face/cover gap adapted to produce suitable, projected holographic content free from distortion caused by the proximity of the face to the wand; and a spinning axis for mounting the wand, configured for rotating in order to spin the wand for projecting the holographic content.
