This item is a vintage 1950s/1960s mechanical wind-up table alarm clock, manufactured in Western Germany.
The case features a distinct Mid-Century Modern "two-tone" styling, composed of a dark charcoal/black enameled metal body bracketed by a bright brass bezel and teardrop feet. It features a unique dual subdial layout on the face: the upper subdial sets the alarm time, while the lower subdial serves as a ticking seconds tracker. The top bar functions as a physical shut-off switch to silence the alarm.
