[time-nuts] Most accurate clock on your wrist

I've been waiting with baited breath for a GPS watch.  NOT a NAVAID on
the wrist but a simple GPS-synced watch.  It would seem to me that
making a miniature GPS receiver would be much easier than making a
WWVB receiver.

Unfortunately that watch ain't it.  Gad, they need a good industrial
designer!  

Maybe they'll put the same electronics in a table/travel clock.  If it
had a 1PPS connector on the back, so much the better :-)
