This 1587  table clock is the masterpiece of the Nuremberg clock maker Paulus Schuster. The large dials on the one side are an hour indicator as well as an astrolabe, those on the other are an annual calendar. The small ancillary dials show the day of the week, quarter-hour and minute as well as serving to set the alarm and the striking mechanism. The silver figures of Neptune alternately move their heads ech minute for 15 seconds, and the rooster on the top crows at the full hour while two men strike the bells.
