    So this is going on on with my AT (3603) 3330 column wheel chronograph. At certain times when I press to stop the chrono the minute hand on the chrono will slightly move forward (like 02mm) and when I press it again for the chrono to continue it will return to its previous position.
    It is hardly noticable and it doesn't always happen.

    The watch was just serviced by omega and has 2 years warranty.

    I'm not sure if this is normal for this movement or not
    Any help would be greatly appreciated.

    Is the 3603 supposed to be a model reference? Because the 3603 and 3330 movements are very different movements (not related at all), so not quite sure what you are referring to.
