    Hi all,

    Does anyone has experience changing the date on the Aquatimer 812? I suppose
    they do not have a quick set date change, but rather one has to turn the time
    until the date changes past 12 midnight, am I right ?

    Hear from you soon!

    I do not own the cal. 8541 D but if I remeber correctly, there is some sort of
    a quick-set function for the date. Try moving the hands from 15-20 minutes
    before midnight to just passed midnight and then back and forth again. This
    may advance the date "widow wiper" style.

    That is correct Ben.
    The hands are advanced past 12 and the date will change, then go backwards
    until you see the date wheel make a little jump, then go forward past 12 and
    it will advance again.
