A travel clock in a brown leather case featuring a silver metal face with black hands and gold painted numbers. To set the alarm, there's a second dial at the center of the main one that features a gold hand. The face of the clock is surrounded by a frame, which is possibly made of brass, and the leather which surrounds the framed face as well as the top of the case is decorated with a dot and oval design in gold. The clock is marked "Eterna" at the center, and directly below the number six on the clock face is the winding knob, which is possibly made of brass. Eterna is a manufacturer based in Switzerland.
