Bought my Oris Aquis date 43mm a few years ago, from a grey market seller (so no warrantee at this point). About a year ago the movement started to behave differently, it would run like a champ within a few seconds a day if I wear it constantly. If I remove the watch for even a few hours, it will stop or lose hours of time. On a few occasions it's even stopped on a winder. So my question is, whats wrong with my watch and how much should I expect to pay to fix it or should I just look for a new movement? Thanks in advance for your thoughts.
