    This is a really nice Rhythm Watch Co battery movement; but a clumsy oaf (not me) knocked the clock off the wall, and it messed up the chime.

    Two notes are no longer chime-y. They are out of key and harsh and ugly.
    I know almost nothing about battery clocks of this complexity, but do you think
    the chime notes could somehow be corrected? I don't even know what part
    of the clock produces the chime, or how it does it, and the likely answer to my question is No;
    but I thought I'd ask. It is a really cool movement, if it could be restored. (I'm thinking
    of making a voodoo doll for the clumsy oaf.)

    It is most likely a hairline crack in the circuit board or a solder connection which became dislodged.
    There will be some kind of oscillator circuit with an IC and a capacitor to generate the tones.
    Try to do a close up inspection and resolder any joints which look suspect.

    Its a longshot but make sure that the movement or speaker is not loose. I've experienced where the speaker was able to vibrate against whatever it was connected to and make some horrible sounding chimes.
