No, it's 12 volt. It's not a continuous current draw. It has a coil inside that acts like a solenoid. It snaps open a set of spring loaded points that make the gears turn. Once the points close again, it gets another blast of 12V to open the points again. In between when the points are open, there is no current draw. Like any other clock, the mechanism can get sticky and the movement stop working. Use some contact spray to clean and lube it.....if you can get inside to do it.
