I've searched around the forum and have not found answers to my questions so I'll ask here. I just got a Marathon GSAR, with the (I think) ETA 2824-A2 movement. I can't wear a watch at work, so it only gets worn around 5 hours a day on my wrist, except for weekends when I wear it almost all day. To compensate for this when I check the accuracy on weekends I usually wind it a few times to keep it from dying. Is this a good practice? If so, how many times should I wind it? Is there a danger or over winding the mechanism? Also, out of curiosity, how long does it have to be worn before it is fully wound, and how long does a full winding last?
