    replace stem on 40 year old Seiko 5?

    My Seiko 5 ca 1970 has the following problem: the crown snapped off flush with the tip of the stem still screwed into it. There are still a few threads left on the end of the stem, but I'm sure I would need to replace the stem as well as the crown.
    I don't know enough about movements to know if this is a prohibitively expensive repair of an inexpensive watch.
    Its value to me is sentimental, so I'd like to fix it if possible.
    Any advice?
    What do you get when you open the box and turn it over and pour it out? What do you get?

    A crown and stem replacement should be a straighforward and inexpensive repair.
    Take the watch to a watchmaker (jewelers usually send watches out for repair). They may recommend a service, but should just do the stem crown & replacement fo. you.
    A service is probably a good idea tho, if your watch hasn't had one in some time.

    Hi.

    I'm not too familiar with Seikos, but in general this is quite straightforward. If you look at this article:

    http://www.pmwf.com/Watches/WatchSch...20a%20movt.htm

    you will see there are various systems. Usually:

    a little screw

    or

    a little button to press down

    or

    a little screw that also has to be pressed down as well as loosened

    or

    a little lever

    and then the stem pulls out. You will need a new stem. If you can't get the tip of the stem out of the crown, you will need a new crown as well. A simple job for a watchmaker if you don't fancy doing it yourself. One of our watchmakers will correct me if I've got anything wrong.

    Marrick -
    that link is wonderfully informative. I didn't realize the stem could be removed/replaced without disassembling the movement. I'll get the watch over to the local watchmaker and have the stem/crown replaced.
    Thank you!

    If you are goeing to do the job yourself,
    How to make a stem correct:
    - Screw crown on stem.
    - insert stem.
    - push stem in winding position (not with Seiko ofcourse LOL)
    - measure the distance between case (not tubus as that one goes inside - crown) and crown.
    - take stem out.
    - unscrew crown.
    - shorten stem with distance measured.
    - file stem end thread round so it won't destroy thread in crown.
    - screw crown on stem
    - mount stem again.
    - control if distance between case and crown is as little as possible.
    not too tight! this will give date change problems.
    - If nesecery take everything out again and ajust stem only with a file!

    SUCCES!

    The Watchmaking Forum was moved from the 'Theme Forums' to 'Main Forums'... that may not have been noticed.

    "The watch has to be surrounded by a history.
    You need more than just a great design. You need to create an atmosphere around the product.
    Who is the company behind it? Why are they using this material?
    People need to be able to identify the watch with themselves. It's based on emotion." - Ralph Furter

    ...that's just my opinion and I've been wrong before and will be again and might be now!
