Set Atomic Watch with No Reception 

The radio signal is an AM radio signal. AM radio basically utilizes long range induction to transmit sound. The signal from ft. collins is at a certain frequency that gets modulated in a certain pattern that the watches decode, like a VERY slow telemetry stream. The app is getting the time from a server and then using the speaker coil to create an RF field at the same frequency as the radio signal and mimicking the modulation. Really, really smart. Put a portable AM radio next to your gshock and press the mode button to trigger some beeps. On any AM frequency, you'll hear the beeps, at the same exact note and octave. Cool, huh?

Great information and presentation shared this with a friend he was working with some others synch issues in the same sort of area as you. So thanks for this I think it will really help.

I’m glad u found this app I love it use it every time and every day for perfect time keeping

You my friend are a wizard !!!! I have the Dw6900 as well and it won’t sync no matter where I am I finally got it to sync using this tip !!!!! Not the same app tho i used a free one ! Thank you !

Finally!!! It worked with the app! Thx mate!! I have the gwg-1000 and never updated until now!

Awesome video, thanks. PLEASE tell me how reach the "get" screen. Thanks so much.

It worke!!! I live in the Caribbean, nowhere near any of the antennas available, although it was worked a few days ago. I tried this with a different app in my Android devive (radio watch sync) and after around 4 mins it synced. Thank you for this.

nice .. it worked on my Rangeman ..where did you get that strap for the 6900 ? iv got one id like to put one on

I am very stoked right now as I believe that this app indeed help synched my watch. Whenever I roughly set it when I first got it earlier today I set it to my car's clock. Which is positively not accurate. About 3 minutes faster. When my watch finally synched it is displaying the exact time shown on time/gov, up to like 0.2 seconds. So it did work. I don't know the heck how. Judging by how you need to hold the watch to the speaker it must affect it via sound, i don't think g shocks have microphones.(that would be terrifying). It seems to first use the much more powerful smartphone antenna to lock onto the radio station then somehow broadcast the info to the watch. How the heck does it do it with sound? I wish I know better. But that was a great relief and learning experience! Again thanks for sharing!

WoW I can't believe it! I really can't believe there is such a thing! I've been using a controlled radio for a while now and I was very dependent on the German radio antenna now that I've seen your video, WoW!Being at a distance (I say quite large) from the antenna, I did not calibrate the time so often, but now with this application ... excellent!On the Android the app is radio watch sync .

Yeeeee ha, perfect ! Just got this App sensational…… what a week, purchased a mint condition GW -9400 Blackout for £105, I looked back on the Sync it hadn’t updated for over a month, within less than 2 minutes boom, done. Thanks a million 👏🏽

Thanks so much !!!! This worked great !!! 👍🏻👍🏻

I got a free app that does the same thing (Clock Sync) for my Casio Oceanus S-100 and it synced in less than 2 minutes. All I had to do was set the watch to R (ready), turn up the volume on my phone to max, place the speaker end to touch the watch, and after a bit, the second hand went to W (work), signifying that it worked. Easy peasy. I only got one successful sync with the Ft. Collins radio wave by placing my watch within my Terk stereo antenna and facing it to the window but it never worked again. Some folk have success by placing or hanging the watch on large metal objects like barbells, pull up bars in hallways, etc. This seems to be the best hack.

Very cool! Thank you Sam 😊👍

Was frustrated getting my gshock to download from the atomic clock. Download this app based on your video and it worked.

Useful. Thanks Sam.

It works , thanks 😊

What a brilliant video, Just tried it on my new Pro Trek pre 35 Works like charm Thanks

wow, love it!

Very cool, heard you talking about this in your latest podcast!

Great info!

I live in Portland which is about the same distance from the Ft. Collins clock as you are. Manual reception is always harder during the day because of other interference to the broadcast signal of the tower. That’s why when my Atomic watches sync with the clock they do it at around 2:00 AM when the signal transmission is strongest due to atmospheric conditions and reduction in interference from other radio waves. You should also keep your watch away from electrical lines in your home because they also operate at 60 Hz. I set my Casio on a table with the bottom or what would be the 6:00 portion of the dial facing the window and it receives and syncs with the Ft. Collins clock every single night without fail at around 2:00 AM. Yes, manual syncing is harder, but that’s because you’re trying to do it during the day when there’s far more interference. I also have a Sharp Atomic wall clock that also syncs every night without fail. Cool app though. I’ll check it out.

Thanks Sam!

Awesome! I am lucky enough to live about 70 miles from the Ft Collins station so I never have any issues receiving a signal, but I was wondering about these apps when the rumor was going around that the government was going to cut funding for the atomic clock broadcast. Good to know this works in case that ever actually happens.

Righteous, I just purchased an atomic citizen only to find that I couldn't get it to receive. Then your video saved the day!

Hello sir recently I bought rangeman gw 9400 so how to get manual signal in India

Great find..by accident or genius!..Well Done. Works great with any metal bar,can of shaving cream or obviously a bike. Thanks for sharing!

Its work thx

I was really skeptical but it actually fixed my WallarGe clock!

I am planning to purchase a g shock model GWM530A-1. I live in the Dominican Republic and I am wondering if the signal is strong enough that when I purchase the watch, it can be able to sync from here with one of the atomic clocks

I love that watch

You're awesome!

What strap adaptors are those? Tks

I can not believe it actually worked. Just picked up a gwf1000 from a bloke nearby. Had to drive about 5 hours round trip. Dropped five bills. So really hoping its worth it. Dude looks honest and doesn't smell like a snake, watch looks great, everything seems to be working. Then I realized the auto EL doesn't work. Solar panel responds to light and that but the screen doesn't show 8888 when I tilt it under the specific test mode. Now I'm stuck on the verge. Is this a high end counterfeit or just has a rather common defect in its tilt sensor?? Only way to find out for sure is to see if it receives. Been running around town the whole afternoon trying to get a good reception. The signal level will fluctuate but never ever got a successful receive. Was getting a bit bummed until I saw your video. Downloaded a free version of such app and wroked on the second time. Now My watch clearly indicates that it has rced radio waves on 10:04 pm. Thank you so much for allowing me to sleep easy tonight.

im planning on getting an atomic watch but I live in the middle east and I won't be receiving any atomic clock radio signals there!! will the app fix that?

I discovered this app several months ago and use it all the time with my G-Shock collection, …it’s great! However, it NEVER works on Sundays for some weird reason, and no matter how many times I’ve tried with any of my watches, daytime or nighttime, on Sundays I always get an error message, …any idea why this is the case?

Really couldn't believe that this works. But I tried it (in Germany) and it dies the trick. WHAT a hack. Thanks 1000 times!!!

Have you ever encountered an issue where your can't manually engage the atomic radio? I have a 5510 and it's not working.

How did you force the watch to go into manual mode?

Really nice to know I have the same watch but I don't have any problems I live in New York I put it up by a window at night and like magic it updates every night

Will this app works for my atomic wall clock?

Probably uses tiny emp from speaker coil. Then all thats needed is to generate a 60 hz carrier wave and modulate the carrier with same information format the radio stations use. Or the phone itself is receiving desired signal, with superior speed and reception of 5g, it's probably able to do real-time transmissions. I don't know how time is established via internet.

Hi dose that app work with multiband 5:)

Sadly it won't work with my old MrG which is set to receive tones from Japan and the USA with their time zones.

Is it important which station we choose? Or must we choose the closest one to our city?

I heard if you attach your earphone to your phone it will amplify thus make the watch syncing time getting easier, probably earphone act like antenna like when you open radio in your phone... Is that true?

I made a surprising discovery when I swapped out the regular bracelet with a magnetic mesh one and was able to connect to an atomic time tower in a region where there's none. Didn't need an app to do this as I guess the metal mesh bracelet and magnet has become an antenna to amplify the signal gathering.

I've watched this video through twice, and it sure would be NICE if you'd give a mention of the app you're using to accomplish this amazing feat! Going by your accent I gather you're a Brit. We Americans need things spelled out for us a bit plainly. So how bout it, sport? Give us a hand here mate? 😎

with my casio mtg there is another step needed. i cannot do a time sync command on watch unless home country is set to a country where one of the transmitters is. i in new zealand. what i do is set my home city to tokyo and second time zone to wellington. in home city mode i receive the signal and then swap back to second city wellington. app works well.

How accurate is the time on your phone, though?

I never had any luck with my G-Shocks receiving the signal either. This is very interesting. I probably will try to se if this works.

Is there an option, to automatically set the app, to transmit the signal? Thanks a lot

I am always amazed at not only how much effort humanity has a whole have put into keeping track of time but also doing so as precisely as possible on a global scale. And we all share it, expect North Korea of course..

I have to oay for the app for just about 2 dollars, but it is worth it... It works!.. Just place your watch on top of your iphone on the upper speaker but do not place it exactly on top of the speakers to avoid magnetism frm the magnet of the speakers.. just place it 1 cm below the upper speakers just enough for the watch to hace L3 signal...

It converts electromagnetic waves to sound waves for the conversion.

I've tried syncing my Casio G-shock with this app, but it doesn't work. I even tried to put the watch inside my Bose QC35. However, when i hanged the watch on my curtain rod, it worked flawlessly

In this video, aren't you holding the watch next to the microphone input, down by where your mouth goes, instead of the speaker output, up where your ear goes? If I know how cell phones work, it sure looks like it to me. Anyway, thanks for this video. It helped me synchronize my watch.

There is no atomic clock in my region, what if i choose local time zone??

Anybody have the android app name

App didn't work for me, but I tried two different ones.

Which strap is that

This is the GW-6900

hello there is a solution to that place your watch on a metal tube place the watch on it as if it were in your wrist and you will receive an atomic signal every night, I do it so, I live in Ecuador South America and I receive a signal from Ft Collins station 😊😊

What happens if i use the the American or the Japanese signal but I'm in Italy?

I don't find this application!? Why?😢

If I bought an atomic timekeeping watch that I had to set manually I would be pissed. Satellite watches are more reliable at receiving the signal, but they’re not without mishaps.

Thanks, eh? 😉🇨🇦

Well my watch is now over 8 months behind. Tried a few Android apps. They don't fix anything. Unfortunately this appears to be an app that might work if I get $1,000 phone to set my $100 watch.

I thought this was going to be great, but honestly how is this really any better than setting the watch yourself? If you prize precision to the second, fine. But if you just want a hassle free watch the fact that G-shocks won’t update on their own is a problem. I wish they would just increase that atomic clock signal output.

Is there an android one that does that ?

use Junghans for Android

It's not a free app 🤔

This is sync with the phone time, not atomic. Gosh, enter your phone clock app. Make sure it shows seconds, click the adjust button on the watch, wait until your phone shows 55 seconds, place your finger on the lower right button and begin counting along with the watch. Press the button when you feel it must be zero. If needed adjust minutes. Well done. Your time is synced.

It's actually 60 kHz not 60 Hz. Only out by a factor of a thousand so I'll let you off. 😁
