The 'Conductor' alarm clocks feature three knobs on the rear of the clock to change the time, alarm time, and turn the alarm on or off.
This 'Conductor' features the ivory case. It was originally available in Ivory or Brown. The clock was manufactured from 1940 to 1942 and again from 1945 to 1947. It was very popular as over 246,000 were sold. The art deco styling features a green sweep second hand and alarm pointer. The center dial turns to set the alarm time.
