I was given a 1973 seiko lord matic (5600-9001) recently and I am very fond of it. The acrylic is in pretty good condition and the case isn't too scared up. There are only 3 problems with the watch. First, the case is a little bit dirty between the lugs. Second it gains about 15 seconds a day. Thirdly, the original bracelet is too small, so I tried to replace it and found that one of the spring bars is stuck. I don't really know what to do with the watch so I came here to get some advice. Should I take it to a local jeweler, send it to the seiko service center (probably a bad idea), or try to work on it myself? If there is anyone on the site that is able to work on the watch I would consider that as well.
Thanks in advice for any advice.0
