Used(not new) clock / timer with part # WB19X73 that was pulled from a 1969 GE Americana range. It is in good clean condition and functions fine. It keeps perfect time and the buzzer works great. You can hear the clock motor running if you put your ear next to it or if it is in the middle of the night, but not too bad. As long as these clocks with the Telechron motors are in good condition and don't lose power they will keep perfect time because they are synchronized with the alternati...ng current produced by the power company. The actual oven it was pulled from is shown in the last photo. Display dimensions: 3-1/2" wide x 4-3/4" tall
