Atomic Watch Sync demonstration - 4 watches (GW-6900, GW-9400 Rangeman)

A cool little video demonstrating my 4 atomic watches getting perfectly in sync after a successful reception after being manually set to the wrong time and date.
The watches are 1xGW-6900 and 3xGW-9400

[@NetAndyCz]

They are nicely in sync even when I look at them frame by frame, pretty cool trick

[@WatchGeek]

I have to admit I didn't remember to check them frame by frame but it's great to know they are in sync even like that, so thanks 😊

[@supermushroomDX]

@@WatchGeek Are there experiments that I can perform to verify the accuracy of a radio controlled clock? If so, I would love to hear from you. Thanks again for taking time to read this! :)

This video really does perfectly show the beauty of any G-Shock with atomic time keeping. Wonderful...

[@xon3E]

Just bought the rangeman and somehow here in southern spain (Granada) it syncs perfectly with L3 (even though it's out of the range according to the range zones map). It's awesome!

[@jonrutherford6852]

Very nice. I like your enthusiasm for this technology, which, though it's no longer "new", is still an example of how science and engineering benefit daily life. Plus -- there's a pleasure in just plain love of gadgetry. Refreshing especially in these times.

[@Mr.M1STER]

It really is impressive and definitely looks cool. I have a Casio 5610 G Shock and it syncs every night at 1am. My watch takes about 2 minutes to complete the sync. I am from Ireland and receive my signal from the UK so I always get the strongest signal L3. I love my Casio.

[@itsallrobbish]

Superb, Ive just got a used GW5610 square with this feature for £50, I live in the U.K. where the signal is strong. The technology is great. As much as I like my mechanical watches, these can't be beaten as beater, fit for purpose timepieces. Approved now for use by NASA, who needs an Omega 'Man in the Moon' now haha. Great video!

[@WatchGeek]

+robert bishop with all the tech Casio offers at these prices the mechanicals do seem outplayed, but there is a beauty in old fashioned gears and I personally enjoy both watch worlds very much :)

[@MrXandi73]

I have the green negative display rangeman. Awesome watch!!! Cheers from Brazil!

[@abdulrahmana8623]

i LOVE the internet! this is EXACTLY what i was looking for. truly thankful for taking the time to demonstrate this cool tech.

[@jasonmiller9495]

I had the gbg-100a3 for a cpl years now and today just received the Rangeman 9400-1 . Man I love this watch . I hardly ever wore the ggb 100 I always chose the Garmin Fenix 6 but that changed today this watch is awesome!!!

[@makigrro]

In my case my G-Shocks sync better when sleep with them on my wrist. Thanks for your great video !

[@salmorreale7900]

Really cool! I cannot manually sync my 5610U, New Jersey USA. However the auto sync grabs it at midnight every time. Thank you for posting.

[@coachafella]

One note, if you are not in range of the atomic clock radio transmission there are smartphone apps that can be used to sync the watch. I have a Casio Wave Ceptor and have used the Android app successfully. The app syncs the watch to the phone time, but there's also an app to sync the phone to atomic time, so there's a fix for no radio reception by the watch.

[@jouwenlee7829]

What's the Apps?

[@coachafella]

@@jouwenlee7829 In the US use the WWVB Emulator app. There's also a version for Japan timezones called JJY Emulator. Those run on Android and use the phone speaker to sync the watch to the phone's time. On Android you can use the ClockSync app to sync the phone time to atomic time. There are also apps for iPhones but I don't know the names.

[@tommasocaretti1810]

Do you have a G-SHOCK with Bluetooth tecnology and without atomic watch? I wish to see if the time adjusted by the G-SHOCK smartphone app through bluetooth will be synced with other G-SHOCK model with atomic watch.

[@noctakus9793]

Hello, I need you to answer a question. I have two Multiband 6 watches, a Rangeman and a GW-7900. They both sync almost every night, but on the 7900 only the tiny streaks appear on the display for a bit. why? Thanks

[@Th3Acc0mplice]

So if you say you’re on the edge at 900km does that mean I will never be able to get mine to sync at 2000km in Georgia? Or is there a closer tower?

[@HitoriGnocchi]

i just tried this with 3 of my solar atomics (GW6900, GW-M500A/M530A) the GW-M500A/530A both synced together but 1 is 1.5s faster than the other. the GW-6900 finished sooner so it has a faster time of 15s ahead of the other pair. In the end all 3 have different times which is really odd. Not sure why there would be such a large difference in time even though in your video all 4 of your started out different yet synced together in the end.

[@maartenvandyck6768]

How to choose the home timezone? Im in antwerp brussels belgium. But paris is closer then berlin. Does it make a big difference? 😁

[@dylangarant3653]

I’m writing this comment on 5-17-2023. Does the atomic automatic time setting still work on these watches?

[@WatchGeek]

Yup

[@JLUnit416]

I had my 7900 next to my new 9400 and I think there was too much RF interference between the two of them. I'll try again tomorrow night, further apart, to see if that fixes the problem.

[@WatchGeek]

+jlunit416 👍

[@kv9395]

Never knew syncing takes so much time.

[@WatchGeek]

The quickest a watch can sync is 2 minutes as that is how long it takes for the atomic clock to send all the information, as it works like someone is telling you: The year is ... The month is.... The date is.... The hour is .... Etc.

[@TheRafala10]

Hi Watch Geek. Do you have any idea why my gw-m5610-1er doesn't manage to connect to the atomic time keeping? I press in the button Im supposed to, and after a while I get an "ERR" (i asume its for error?) and nothing happends. I live in Stockholm, Sweden if its to any help at all.

[@WatchGeek]

It should work in Sweden IF your home city is set correctly. Also just in case, watch my DIY ATOMIC AMPLIFIER video and try that technique over the night

[@TheRafala10]

@@WatchGeek Yea its set to Stockholm...strange. I will check your video out!

[@TheRafala10]

Thanks for sharing this demonstration! I own a Gshock GW-5510. It hasn't synced in the past three days. I haven't made any adjustments to the watch and I place it on the same window sill each evening. I live in California and read in the owners manual that there may be occurrences during certain times of the year or day where syncing is not possible?

[@WatchGeek]

+Under The Bus thanks for watching and yes, there are so many factors affecting reception that there can be days between successful syncs.

[@unknownanonymous123]

Did you have to place all 4 watches facing close to a window in order to receive the strongest signal? I've had trouble syncing atomic clocks in the past since I live in an area where buildings are in very close proximity.

[@WatchGeek]

In this part of my house I have no problems but in other parts I do. I however discovered a simple solution where I get the signal EVERY NIGHT and ANYWHERE in my house. Check it out, as it might help you too: kzbin.info/www/bejne/rXqXd6qHgqiBb9k

[@daliborfijan7126]

⁠@@WatchGeekZnam da je ovo stari post ali otkrio sam jednu foru za bolji signal kod multiband sinkronizacije. Puno je bolji prijem ako se sat stavi kod prozora tako da mu je stražnja strana okrenuta prema gore, lice sata da bude dolje a narukvica zavezana kao da se nosi na ruci. Vjerojatno je tako djeluje kao antena i jako poboljšava prijem. Odličan je kanal i redovito pratim nove recenzije. Pozdrav 😉

[@davidcollins4227]

Nice experiment. Have you heard about the rangeman lugs breaking where the strap is attached? Have you had any problems with any of yours?

[@WatchGeek]

+David Collins yes I've heard of that but had no issues with mine x however I do avoid stressing them at an angle that could cause that, such as doing push ups with the watch on

[@davidcollins4227]

Watch Geek thanks. I have just got the rangeman and think it's a lovely watch indeed. I also have the G9300 mud man which is also fantastic. I got the rangeman to replace my riseman GW9200 because that watch had a problem with some of the LCD segments fading only after about 1year of use. Not sure why that happen and Casio just replaced the watch with the G9300. Also what's really strange is I have a Protrek prw 1500 and that has developed the same issue with the LCD. Not sure why this has happen but that watch is under warranty and going back for repair for the 2nd time for the same issue! I hope the mudman and rangeman don't suffer from this LCD corruption fading segments etc.

Very cool video! Do they always sync at 2 a.m. watches time?

[@sajidkhanmahmood]

12am 2am and then 3am i think

[@alt0v14]

Strange thing, when I put my gw m5610 on the side (it's natural for this watch because it can't lay straight) it doesn't sync :(. I beleave this is all about antenna position. I am living on the 1.5 kilometer edge from german tower.

[@WatchGeek]

In 2 weeks I will be posting a video on increasing the reception capabilities that I discovered recently so stay tuned!! I am also on the edge of the German tower and sometimes mine sync, sometimes they don't. After using this newly discovered method they haven't had an unsuccessful sync in 4 weeks straight

I am 2120miles (3,411kms) away, but in the casio manual it says that it should cover my area. Do you think this has to do with not being able to sinchronize them? thanks for the help.

Do you use only one Rangeman?

[@bradsbunker]

[@94SexyStang]

I hate atomic.......No signal anywhere, what's the point!!!? I appreciate the fact they atleast put an "off" function to turn atomic off.......but it's just kinda stupid......not even 1 signal bar.......really thinking about taking this watch back!

+Loco Patojo thanks :) it is an incredible tech

[@a2eorigins]

Does anybody get the message "GET" after the synchronization is complete?

[@RockyBoltzano]

Yes, I do get the "GET" message, however, my watch is just a basic Wave Ceptor, not a G-Shock like these in the video.

[@loghome7061]

Is the 6900 a larger watch than the Rangeman?

[@WatchGeek]

Log Home not on paper, but because it has a pretty wide arching strap it sometimes wears larger on some wrists

[@dnationapocalypse]

Watch Geek do you have to sync at exactly 2a or as close as possible to 2a because i can't get my Gshock to receive the signal. I had no problem with my Citizen.

[@WatchGeek]

It has to be in the night as there is less interference. You can try my method I explained in my DIY AMPLIFIER video as it makes all my wathes sync every time

[@zarulkhaliff5107]

where did you do this? in your house? because mine never worked and I only got L1.

[@WatchGeek]

+Zarul Khaliff yes, in my house. The signal strength depends on many factors including distance from the tower, whether there are other buildings or power lines around you and interference of the Sun

[@zarulkhaliff5107]

Thanks Watch Geek. Actually, I've found a way better. Just use JJY simulator in case we only received L1 signal. Install that app, start the RC on a g shock and run the simulator and all we need to do afterwards is wait. :)

[@WatchGeek]

+Zarul Khaliff I used it on one of my watches, the problem is that the home time has to be selected as Japan, so the world time function is off, and if you switch the time zone back to your time, the watch deletes the RCVD symbol

[@zarulkhaliff5107]

Thanks dude, I just realised that. :( By the way, thanks for the great video!

[@WatchGeek]

+Zarul Khaliff thanks for watching 😊👍

[@RagingBad]

Im in Florida and my watch is having a hard time picking up the signal

[@WatchGeek]

You should check the coverage map for your radio tower and see if you are within reach, but even if you are, some locations can have trouble getting signal due to different factors (buildings, power lines, mountains etc.)

[@RagingBad]

Thanks, the tower in the US is located in Colorado, tonight I'll point the watch on that direction and see what happens

[@WatchGeek]

+maximus10463 according to the map you should be able to get it to sync, you are far, but still within reach, try different positions in your house or apartment. Mine syncs better in a room pointing in the opposite direction to the tower, so I guess it depends on many factors

[@RagingBad]

Will do, im even thinking on putting it on my car outside

[@sajithwijekoon1313]

I am in Sri Lanka can I Sync my GW 6900 watch also? If so how? Please educate me.

[@WatchGeek]

+Sajith Wijekoon I don't think it's possible since you are too far away from any of the towers

[@vasantha0771]

Sajith Wijekoon U can use JJY SIMULATOR

[@sajithwijekoon1313]

Vasantha 07 What is JJY SIMULATOR?

[@WatchGeek]

JJY simulator simulates the signal from the Japanese atomic clock making it possible for an atomic reception watch to sync using your phone. The bad thing is that the watch has to be set to TOKYO as the home time zone meaning the world times will be wrong
