Have had my fossil titanium watch now for about 12 years and recently after the last battery switch my watch has been slowing down randomly and is behind maybe 30minutes when it does slow down. I originally thought it was a weak new battery so changed it out to a brand name battery and it still does it. If i wind it back up to the right time, its fine but will lose another 30minutes some random time in the future. THis hasnt happened before the latest battery changes. Did i damage the movement when swapping batteries?
