Pivot point of watch hand wobbling

I created a watch hand from a jpeg image and applied it to my watch face in GWD. It appears to be centered visually. However when it rotates, the rotation point of the handle wobbles slightly up and down and left and right - maybe a couple of pixels or so. How can I fix this?
Thanks in advance for any replies,

I found you can right click the watch hand, click Show Pivot and the you can grab the pivot point and move it around. Problem solved for the watch hand.

One of your parameters like rotation angle start point end point and/or pivot is out of sync
need more info with images

I believe you need to use a .png file instead, I think that is the issue. I know it is an issue with animation.
