    Question on Seiko SEIKO 6139-6005 VINTAGE CHRONOGRAPH 1975?

    Hi All,
    About a month ago my Mom found in her things my Seiko I had left at here house during a visit 20 plus years ago and we had both forgotten all about it. I believe I bought this in 1975 or 76 don`t remember for sure.It still runs but I believe it needs a cleaning. It makes one second hand rotation then stops a 12, shake it and it makes a full rotation again then stops a 12.
    Any help from the experts would be appreciated. I would like to sell it and need to know as much about it. SteveName:  400637462.jpg

    Turn the chronograph off (top button - once) and wear it for a hour or two. It should now be wound enough to play with the chronograph functions.

    Test 1 - Start the chronograph. let it run for a few minutes. Does it work?

    Test 2 - Time the chronograph against the time only hands. Set the hands to 12:00 and start the chronograph. After 10 minutes check the minute counter against the minute hand. Do they agree?

    If the answer is 'yes' to both then it is worth getting it serviced.

    Thanks I will give it a go.
    Any idea on the year produced? I think it was 75 to 77? and its possible value in good working condition?

    The manufacture date is April 1977 from the serial number.

    Your best bet for value, is to look at the trading forum for similar models. Use 'Pogue' in your search as well.
    Do the same search on eBay under 'completed auctions'. This will give you a good idea of it's value in it's current condition and what it could bring if properly restored...the value will range from lunch money to many hundreds of dollars.

    I saw one just recently. Not as good of shape though and no bracelet and the seller was trying to BS me. When i mentioned the poor condition he withdrew the watch and said i dont get the appeal (!). I think it is a cool watch if you can get it working.

    Thanks for the input guys, I have a very nice dress Seiko that I only wear when I go out with the wife. Never like wearing a watch and always carry a pocket watch, so I will put it up on ebay or consider any offers, It seems to be running fine, the dial turn very smooth but I have no need to put $75 to $150 into restoration into a watch I will never use or may not sell. I dont know if it will or would need work since it sat in a jewelry box for over two decades. But it is a one owner watch that I think is in good shape, so for those that might like it send an offer.
    Thanks again Steve
