The clock is housed in a wooden case adorned with carved ornament, featuring a glazed front door that opens by pressing a button on the left side panel. At the bottom of the right side panel, there is a hole for the playback device drive handle. A white enamel clock dial is mounted on a brass plate, featuring black Arabic numerals indicating the hours, two black hands, and a hole for winding the clock movement with a key. The clock movement is a pendulum type with an anchor escapement and a spring motor. Inside the case, behind the back door, is the playback device mechanism with a soundbox, a small upward-directed horn, and a tape-drive mechanism for a 50 mm wide and 99 cm long celluloid tape loop, which contains 48 recorded sound announcements of the current time from noon to midnight every quarter of an hour. A sheet of paper with a diagram of the playback device is pasted onto the inner side of the back door. There are openings for sound output on the top panel of the case and the upper part of the back door.
