    Re: G Shock Signal Reception

    I'm near Indiana's north shore, so not as far from CO. My first
    tabletop/battery powered RCC was a Sharp. It worked off and on for maybe
    a week and over a period of 8 years has not received a signal since
    either manually or automatically. My second table top unit is a
    Presidian. It loses about a second a day (not good) but will reliably
    reset in the basement of a brick house with 3/4" oak floors. I had to
    put it in a steel ammo box surrounded by ammo against the basement's
    west concrete wall and shooting through the garage floor to stop it from
    receiving so I could rate it over a 10 day period. So it seems like some
    are natively excellent, and some are just duds.
    
    As to the Casio wrist watch, I recently purchased a $30 Casio Wave
    Ceptor RCC with stainless band (tired of $10 band replacements on $20
    watches). It may not reset on the first auto attempt, or a manual
    attempt under iffy atmospheric conditions past midnight, but has never
    failed to reset if left on the ground floor (on my wrist or on a counter
    top). Having rated it over a 20 day period when new, I now leave it on
    the night stand in the basement, and that little bugger resets about 80%
    of the time. It might take several attempts and finally succeed at 4:06
    AM EDT, but it gets it done.
    
    Mine has the ability to shut off reception, so I did that to rate it
    over 20 days when new. It runs 0.1 sec fast per day. A wonderful feature
    is the ability to press the "D" button and it tells me the date and time
    of the last reset, so armed with it's rating and time of last reset, it
    is no big deal if it misses a reset or two.
    
    This is a long shot, but unless you are that rare male who can resist
    the urge to play with your new toy's features, could you have
    inadvertently disabled the RCC feature? Not likely for a person of your
    acumen, but other than that yours may fall into the "dud" category and
    should be replaced under warranty. If you bought it through Amazon and
    are within their return time limits, I would suggest sending it back for
    a refund. Then purchase one with the display you want. A win-win.
    
    As to rating it against a known standard and using the nist time.gov
    site I hold the watch over the computer screen with the face next to the
    computer second display and focus on the watch face. While not in the
    Fovea centralis, I can observe the motion of the nist digits and if I
    know the rough difference in seconds it is relatively easy to spot the
    sub-second difference without shifting my eye.
    
    The optimal solution is a time tick. I use a $40 pocket radio (Kaito
    KA11) which can receive the 10 MHz and 15 MHz broadcasts. Despite their
    claim that the nist computer display is "corrected for network delay," I
    often see/hear a slight difference (maybe 0.2 to 0.3 second).
    
    The above is a long ramble to suggest you have a lemon. Holding your jaw
    and tongue in the right position, standing on your head in the
    north-west corner of your yard while chanting won't alter that fact :-)
