These are balanced 10 inch second hands designed specifically for use with our Q-66 and Q-67 Continuous Sweep high torque movements. They will not work properly on any high torque movement that has a "stepping" second hand motion. If you are using hour and minute hands, make sure that they have a minute hand that is less than 17 inches long from the mounting hole to the tip.
Hour and minute hands are sold separately.
These hands require a High Torque (Higher Power) Clock Motor. You can find those motors by clicking here. Looking for a Pendulum or Chime Clock Motor? Click Here and choose a High Torque Option.
