A circular knitting machine for knitted or hosiery items includes a supporting structure; a needle-holding cylinder rotatable around an axis of rotation and supporting a plurality of cylinder needles that are movable for producing a knitted fabric; a dial assembly, arranged above the cylinder and comprising a needle-holding plate rotating around the axis of rotation and supporting a plurality of plate needles that are movable for producing a knitted fabric. The machine includes motion generation elements, in order to rotate the needle-holding cylinder around the axis of rotation, and motion transmission elements configured for forming a motion transmission chain capable of transmitting to the plate, synchronously with respect to the cylinder, the rotation generated by the motion generation elements. The motion transmission elements include a first toothed wheel, receiving the rotary motion of the motion generation elements; a second toothed wheel, mounted coaxially with the needle-holding plate; an offset device, located between the first and the second toothed wheel and comprising an inlet gear, engaged with the first toothed wheel, and an outlet gear, engaged with the second toothed wheel. The inlet and outlet gears are mounted coaxially with one another and are translatable by an actuator, so as to change the engagement of the inlet gear with the first toothed wheel and/or the engagement of the outlet gear with the second toothed wheel.
