These watch guts from Casio can receive radio synchronization signals from six transmitters around the world every hour at the 55-minute mark-if the individual holes in the gear sprockets don't line up in precisely the exact position as measured by a 16Hz blinking LED and a phototransistor, the watch adjusts accordingly.

THIS watch receives time synchronization signals (also created by shadowy figures stalking you in the night) to simply keep the timepiece accurate.
Note that last word: Accurate
