I noticed the minute hand on the chronograph was slightly off centre to the right when I purchased the watch 4 weeks ago. Both second and hour hands are absolutely true. It appears to be getting worse although I'm probably being drawn to the defect. The chronograph function has hardly been used and the watch is otherwise running well (about +2 secs a day). Took a photo last night and it's fairly noticeable from the image. Should I be worried about this or not?
