Pivot point sets hand to the center of the clock face.
The transform center, or pivot point, is the spot about which a rotation takes place, or to and from which a scale occurs.
All objects have a pivot point. You can think of the pivot point as representing an object's local center and local coordinate system.
The pivot point of an object is used for a number of purposes:
As the center for rotation and scaling when the Pivot Point transform center is selected
As the default location of a modifier center
As the transform origin for linked children
As the joint location for IK
You can display and adjust the position and orientation of an object's pivot point at any time using the Pivot functions in the Hierarchy command panel. Adjusting an object's pivot has no effect on any children linked to that object.
