Radio Wave Sync

Incredible. Bought a new G-Shock that was giving me trouble getting time sync. Technically I don’t live that far away from Colorado, but getting a good time signal is difficult, even at night in a window facing southeast. Been strapping it to metal bars and trying different positions and nothing. This app got it to sync. I have no idea how this works and I even have a HAM radio license. Good work!!

I have a Casio wv-58a and it seems to have trouble picking up time signals where I live. If it’s anywhere away from a window at night, it won’t sync. I read about these types of apps and wanted to try one for a ‘just in case’ scenario. For this to work on my watch I had to place it face down, 12oclock facing my iPhone XR speaker. And it worked!

Synced my Casio Protrek in less than 2 minutes, and is dead on with NIST time. Didn't need headphones or anything, just turned volume up all the way on iPad and set my watch next to speaker 12 oclock position facing speaker, and that is all.

I’m not sure how but it works. I’m in FL and too far from atomic transmitter and rarely get automatic time updates. I placed my Casio watch face down with 12 o’clock up against phone speakers, about 2 min a successful time GET.

I live in NYC, where the signal is very weak. By using this app, my watch miraculously gets the signal and sync with the US signal station. Thanks
