The device described in the question is an actigraph, which is a wristwatch-like device that records movement and can be used to assess sleep. The other answer choices are not specific to measuring sleep and do not involve movement recording. A polysomnograph is a comprehensive sleep study that measures brain activity, eye movement, and muscle activity in addition to movement. A somnograph does not exist. A polygraph is a device used for lie detection.
