I disagreed and said that yes, something with a 1 inch antenna might at some time of the day might just get a strong enough signal to update, but that I doubt it couild update on demand, becaue there are times when the band is no good.

I have owned for many years now a Casio "Wave Captor" watch that 
automatically tries to receives WWVB (60kHz) every night, between 0300H 
and 0500H.
It does synchronize whether I am in San Francisco or McLean (center of 
the World). Would not work in Alaska last August. Does not work in Europe.
This morning it synchronized itself at 0505H (McLean time)
Never heard of a short wave version, although it might be possible to 
hear WWV on 10 MHz  most of the day
What was the make of your friend's watch ?

(There is apparently a newer version that can receive, in addition to 
WWVB, similar VLF signal transmitted within Europe)
