I was skeptic at first but it works. I have a Casio G-Shock GW7900 (3200). Some atomic radio signal watches must also have a speaker in addition to a radio antenna. Start the app, crank up your phone volume to maximum, and point your phone towards your watch at close range (almost touching). I had my phone pointed at the right side of my watch.

The best weather app ever. You will be happy!
