    Hello, would someone please help me with this Gruen caliber watch. The stem falls out and I do not know how to repair it. It was a presentation watch from 1972. Thank you.

    Hi Old Man 2011,

    I do not know which caliber 513CA could be, I am only aware of a 512CA and a 518CA, but I have not seen them all yet.
    The 518CA would be a Gruen labeled AS2063 movement, also 25 jewel, so I assume it would be at least similar.
    If you open the back of the watch and put the watch with the crown facing away from you, you should be able to locate a tiny screw left of the stem.

    Slot in the stem fully and fasten this screw with an appropriate screw driver. This should be it.

    Just checked a closeup photo ot the 518CA which I own and had to find out that this movement does not have a screw at the described position but kind of a pushbutton. Need to have a closer look to the movement later the day to see how the stem can be tightened in this case.

    Some watches with the ETA 2824-2 automatic movement were sold under the Gruen name some years ago; don't remember when I got mine. Walmart had the watches for a few months. That movement is behind dials with many names on them.

    OK, I checked the movement. If the stem stays loose with an AS2063 I think the setting lever jumper is either broken or best case it is loose. Same would be if it is an AS 2066. But may be you are lucky and your movement has a detent screw and all is fine...
    In case of an AS206x movement you need to remove hands, dial, datewheel and probably some other parts to access the setting lever. A fresh one looks like this:

    Best case the screw which sits in the upper whole of this photo is loose, or something is broken. You may get an idea of the movement if you take a look here:

    Unfotunately German but the photos should give you an idea...

    When I went to attach these photos, I notice that the stem is broken. Now I know why it falls outs! Now, how do I get the broken part out?
    Thanks for your help everyone.

    OK, looks like it IS an 518CA aka AS2063 movement. You need a pair of good tweezers to grab the stub and push the button next to the stem with another pair of tweezers or something else. While pushing the button, pull the rest of the stem out...

    Well. I am having a bad day. Yes, of course you are correct, it is a 518CA not a 513! I have tried to get this out but I have decided to take this to a jewelry store as they will probably have the tools. Thanks again
    everybody​
    for all your help.

    That sure looks like 513 in the photo. Not that it matters as far as the problem is concerned, the instructions are the same. Peter

    I'm curious about the LCBO marking on the dial.... as in the Liquor Control Board of Ontario?

    Where did you get the watch?
