Existed everywhere in the world since radios became common. I have an old solar powered Casio g-shock multi-band watch and it gets signals from transmitters located in US, Germany, UK, 2X Japan and China. I have never needed to put watch on time, or change batteries. https://gshock.casio.com/intl/technology/radio/ https://gshock.casio.com/intl/technology/radio/

These are indeed very cool! If for some reason you are a few standard deviations more paranoid about not having the correct time than the average person, they now apparently have models that can get the current time via GPS, time beacon, or Bluetooth from a connected smartphone :) https://gshock.casio.com/us/technology/3way/ https://gshock.casio.com/us/technology/3way/
