I commented on another RUclips channel that I could not figure out how a smartphone is doing this using the speaker. The issue is that a speaker produces a physical sound wave that propagates through air, while RF, or radio frequency consists of an electromagnetic wave. (Absolutely fascinating by the way; an RF wave does not need a medium; it consists of two wave-forms: electric, and magnetic which are at 90 degrees from each other, so that each component uses the other as the medium through which it propagates.) I have dug a bit into this phone technology used for this app, and apparently unshielded speaker wire can produce an RF transmission, so I assume the developer(s) behind the Clock Wave app (and others like it) have determined the right signals to send to the speaker that will produce the right RF signal - kind of using the speaker wire as an antenna. For WWVB I believe it is 60 KHz. It seems like it would be a bit tricky to modulate the amplitude in the right way to send data, but that must be what they did. I have a few multi band 6 watches, and they all sync successfully to this app.
Thank you for this amazing video, on my g shock gw 9400 rangeman some days it doesnt sync with the tower, when I'm bored or when it doesn't sync for a good amount of days I will definitely use this app to sync it manually, but where I live it should not be an issue tbh but still an amazing app for people who have trouble connecting to the tower
Thanks! If you’re interested, you can see how I made that sign on a video from my other channel. ruclips.net/video/kOt9x4oh6ok/видео.htmlsi=WSXB74kmalgtCfog
It's going to use your phones time not the actual atomic time. I live in VT and get the time sync about %75 of the time. You have to put the watch next to a window that faces colorado, its a very low frequency signal and will not be affected by most weather.
It transmits the phone's time. The phone is producing a radio signal that is theoretically identical to the signal from the actual radio tower using the phone's time. The phone syncs with an Internet time at least once per 24 hours, so it should be accurate to within less than a second.
I would pay 2 dollars on a iPhone app only if it guarranteed world peace, the end of hunger and no suffering for children. And I would be just as excited and happy about it as this guy is. But for an app that helps sync your already super-precize quartz watch with an atomic clock... it's just stupid.
Pain in the neck to use an app for this. waste of time for something that is supposed to be automatic every night. Look for Arduino or Raspberry Pi projects to do this automatically every night, or set up an antenna to get a better signal.

There's a free android one - radio watch sync
Faster and cheaper to look at phone time and reset the seconds manually on the watch.

Just Wow… Also your Sign is amazing..

Now this is super cool!
Thanks, Sammy! I’m glad you like it. Yes… it is cool! 😎

Excellent video, clear explanation
The actual time will be phone time or the atomic clock time that will get synchronised?

I tried this app on my Casio G-Shock watch and it didn’t work
Oh no! That odd. It sucks too. Sorry it's not working for you.
I found this app two years ago and it really does work, although sometimes it takes several minutes.
Yeah… it does take a while. Still… I’m glad it works.
If only this video was released 1 month earlier.. I wouldve bought the multiband version :((
Bummer. Well… perhaps you can add it to the wish list.
Well, you need and Apple smartphone? Now way for me, this brand is not compliant with my values.

Sir, do you have any link please?
