    Loose watch crystal

    Hi again all!

    Unfortunately I'm in need of your words of wisdom once again! This time with a situation not of my own doing!

    One of my watches' crystal fell off today all of a sudden. I've placed it back on and it fits snug which holds it on. But when I touch it, it quite easily comes loose. I've seen on the internet that it needs gluing down with some cement. But before I do so just wanted to check if anyone has any other advice?

    Thanks a lot :)

    It has probably been replaced prior to you buying it with a crystal that is slightly too small. The crystals for these watches should fit tightly without the need for any glue.

    So what to do? Well, firstly, if you do not have a replacement handy, then carefully replace the crystal you do have so that the hands or the dial do not become damaged.

    If you have the tools and know how, find a replacement crystal of the correct size. If you do not have the know how, then you will need to find a watch maker who can do this for you. It is a quick and easy job but requires the tools and know how.

    Hope that helps.

    Thanks Sekondtime. That's really interesting! I don't have any spare crystals and I imagine that the one I would need would be only a fraction larger than the current one (ie very likely for me to buy the wrong one). I'll have a look around on eBay but I imagine going to a watch maker may be the best option.

    If the crystal is reasonably good fit (not way too small) then you can easily address this issue.

    1) get the crystal glue from the ebay. GS HYPO CEMENT GLUE HOBBY, CRAFT AND WATCH CRYSTAL GLUE. Just a few $
    2) take the watch mechanism out. Let me know if you need help with that
    3) clean the groove that the crystal goes in with a toothpick
    4) glue the crystal in. Remove excess glue with the rubbing alcohol. If you mess up, remove the crystal and repeat.
    5) put the watch back together.

    Later, if you happen to get the better fitting crystal, remove old (rubbing alcohol to the rescue) and put the new in.

    Good luck.

    Does Isopropyl Alcohol dissolve GS Hypo then?

    Yes, This cement is not something that hardens as a ‘stone’. It is similar to silicon. Stays a bit soft and flexible. The box for the glue has the instructions how to apply it. Once you put the glass in some of the glue will be squeezed out to the glass. That I promptly clean with the alcohol.

    You can also just rub the excess with a finger. Hypo cement "pills up" similar to rubber cement or partially dried hot glue

    For crystals I use Henkel's Pattex Total Gel. Looks like this:
    100% Repair Gel
    It dries in about 15-20 minutes (easier to work with), and it turns into transparrent rubber silicone. Very easy to remove later, it detaches in one piece. Sounds a lot similar to what Odessa proposed.
    Also it's cheap and available in many stores.
