Daytona sub dial hand movement

[hsung]

I have stopped my Daytona's timer hand at 53 seconds or so ... where it does not obstruct the words beneath 12 o'clock, and the minute and hour sub dial hands are still pointing 12.

I have noticed the hour sub dial hand moved slightly to the left after some time without any major bumps I can recall. This has happened twice now and I had pressed the reset button to reset the hands before stopping the long hand at the same position.

Has anyone experienced this and should this be a concern?
