    Crystal change on a DW-8200 Frogman


    I haven't opened the case as yet, but was wondering if anyone has replaced (or attempted to replace) a crystal in a Frogman DW-8200. From the way it looks, it appears to be a standard circular crystal (not sure about the thickness yet) and should be fairly easy to replace. It does not appear to be sub-surface printed, but I can't be sure until I open it up. I have a crystal press and likely the correct size crystal (as long as it's nothing unusual) so I was wondering if anyone has any experience in this little project. Thanks in advance for your input!

    Re: Crystal change on a DW-8200 Frogman

    Update on this project! I stocked up on a supply of various appropriate sizes and thicknesses of mineral crystals and proceeded to remove the caseback, gaskets, movement etc. and got to the plastic "dial" insert (the part with the windows that separates the display segments). This part is "keyed" in and it seems as though it is dropped in from the front of the case, before the crystal is installed and actually held in place by the crystal. Problem is, as I see it, there is no good or safe way to push the crystal out from the back of the case without destroying the dial insert. Is this correct? Has anyone been able to remove the old crystal without damage? Or should I just give up on this project and live with the crystal issues?

    Based on my spare 9200 case, the crystal goes on top of the plastic dial dividers, so I would say that the plastic part is set in first and the crystal is then pressure fitted over that plastic part. I think you will have a bear of a time to remove the crystal without damaging that part. I guess that's why Casio sells the whole case as a spare with everything already fitted already in place.
    Cheers!

    If you are definitely going to replace the crystal, why dont you break it first and you should then be able to remove the pieces without damaging the plastic insert.

    Thanks for the replies! Mitch, I considered breaking the crystal, but I would risk damaging the insert. I guess if it bugs me too much, it's time to contact Casio!

    Did you remove the pusher stems? They are held in with e-clips.

    Rogerlike, I thought about that, but it didn't look like the case would have come apart into two pieces, nor did it look like it would have made a difference. At first, I did think that by removing the pushers, the case had a metal insert that would come out and release the the dial insert, but I didn't see any seam or a way for the case to come apart any further. Was I wrong?
