Counter-clockwise hour ”motor” doesn’t work

I have a Vivomove Sport hybrid smartwatch,  from a while I started to notice a frequent misaligment of the hands.   Already tried all Garmin procedures for aigning, even asked to support but did not received any answer.    Then I noticed that the problem is only with the hour hand.   When both hands align 9 - 3, the minute hand always work fine returning to its original position but the hour hand has an erratic movement.   After some tests I found out that it only moves CW (it shoud have both CW and CCW movement), even when trying to align this hand.   It is probably a mechanical issue, but haven´t found any solution yet.  If someone already solved this kind of issue, please help me.
