Parsec Enterprises Inc.
    They do LED watch repairs but I have only my own personal experience to verify this. I do not know if they repair all brands or not. A phone conversation with the receptionist there told me they have one man that does LED repairs and repairs can take a long time. If you have dealt with them, please let me know! Their website has good information about Pulsar LED's including a small FAQ.

    Talking watches (and other things) from Maxi-Aids. They specialize in items for impaired people, but the talking watches ingest batteries much like LED's, so I thought a link would be appropriate!
