NIST (aka bureau of standards) invented an atomic clock movement that is the size of a grain of rice. That's almost good enough to fit in a self-setting wristwatch, if they can get the power needs down enough. A radio-controlled REAL atomic watch would be awesome, as it'll never be more than a few milliseconds off at any instant. The watch could even be designed so that the user sets in the city and it compensates for time of radio propagation. (like about 5 milliseconds from the WWVB transmitter to Chicago) An "atomic" watch is as of now is no more than a half a second off at any time, good enough for human affairs. (but not for a good time nut!)
