I think it would be limited by ergonomic considerations (size of buttons limited by fingertip size?) and probably battery technology because GPS transmitters tend be quite hungry. I'm guessing something around the size of an IPod Shuffle?
Breitling once made an Emergency Transmitting watch that had a pull out aerial that could only be used once before being sent back to the factory for resetting.
So again something watch / IPod Shuffle sized i would think.
Just a guess...
