Continuous sweep, High Torque C battery
This standard size quartz movement uses a "C" size battery for long battery life. Use this movement with any of the hands for quartz clocks we sell (including our extra long hands). This model is for dials (faces) up to 3/8" thick. Continuous sweep means that the hands move smoothly rather than once per second as in a step quartz movement.
The shaft diameter is 3/8", the threaded portion is 7/16" long and the total hand shaft length is 7/8". And yes, it can use a sweep second hand. The movement box is 2-1/4" w x 2-3/4" h x 1-1/16" thick
Face and dial thickness is how thick the material is that the hand shaft goes through.
