How difficult, for a watchmaker, can a G-SHOCK Carbon Core Guard be to stripdown completely, clean, rebuild and configure? This sounded like and interesting challenge and it came with the added bonus that a would create a video, this video, filled with rare footage of what is actually inside, deep inside, a G-SHOCK watch. Challenge Accepted !!!

Really enjoyed this - perfect with a Saturday morning mug of coffee. Im slightly embarrassed to say (although only slightly) I've got 5 gshocks now, mostly picked up used from ebay, and have had a couple open to change batteries. The debris that fell out of one of them was enough to plant a small plant, but under the real caseback it was mint - amazing really.
Thanks.
im a blacksmith based in Texas, i put my g-shock through absolutely horrendous conditions its the only brand able to stand up to the abuse. love it.
I'm a watch and clockmaker. I've owned my G-Shock since 1989. Only had to replace the battery once. It's now on year 9 of battery number 2. I even done a video of me throwing it at a pebble dashed wall and 50ft in the air to prove how tough it is. It'll outlast me.
I believe the limit is 2039, when the calendar reaches its limit. Newer gshock limit is 2099.
thanks for the info, it means a lot to me as a first time used of an original g shock ga 2100 sir...
@@KarunaMurti interesting, I’ll have to check mine out, then, I have a 1984 DW5200 (Hero)
@Karuna Murti I read there are ways to work around the year limit. Just set it to a year in the past with identical day/week.
@@KarunaMurti yes, it will explose then. True story
This gentleman made a charming and humble little video, demonstrating skills most of us will never have, to entertain and educate. And yet receives negative comments and even personal put-downs from viewers who seem to take themselves too seriously. Enjoyed the video. Encouragement to continue.
Don’t own a G-Shock. Not a watchmaker. Not sure why I’m watching this but it’s bloody marvellous! Great content. Thank you 🙏
Well done, Richard! In this episode, you have satisfied my undying curiosity of G-Shock watches. It has always fascinated me on the inner workings of these iconic watches. Once the watch was reassembled, and I witnessed the functions as the mode control was manipulated, I now realize the necessity for two batteries. This was quite enjoyable, and educational at once. Thank you for posting! Cheers!
Great feedback Alex! Much appreciated! Richard
Richard, when I first saw you doing this I was like "Why is he servicing a g-shock?"
Then i saw the crud that had worked its way inside.
So while a digital doesn't need to be serviced in the same way a mechanical watch does, it still needs to be cleaned occasionally. Bang on video, mate!
Hi JToddHubbard7 .... I did 'go a little further' a little further than was strictly necessary to remove the crud; but it was interesting right? An occassional clean as you say is a good thing with all watches I guess. Thanks for the feedback. Richard
Richard, I must admit I felt more anxiety watching you work with this module than I do when I normally watch you with mechanical watches. "Accidentally too deep" is a super scary term!
Hi Clay! Great to hear from you! Yes ... I was not really in my comfort zone. All's well that ends well though I guess! Richard
How nice you live in Pembroke Dock! I lived there as a boy in Gwyther Street, and my Gran and Gramps lived in North Street. My Gramps was the shipwright who built the Cleddau King & Queen Neyland ferries, and my Dad flew Sunderland bombers from the dockyards in WWII. Love Pembrokeshire.
Hi Eifion... That's amazing! Your family are truly Pembroke Dock with both the Shipwright and Sunderland contributions! Brilliant! Maybe you were here in The Dock's golden era... It's a little run down in places at the moment but I do like living here... Always something going on! So nice to hear about your family's connection and contribution to The Dock! Richard
Brilliant mate, love my G's. They're in rotation with much more expensive pieces but I get just as much if not a little bit more fun wearing them.
Appreciate seeing the guts of one, cheers my friend 👍🏼
Very interesting, I have only owned square Casios and never bothered to learn what the innards looked like on the other models, it having stepper motors really blew my mind. Very nice content 👍
If it's any consolation for forgetting the hands, I tried cleaning my old DW-2500 once and finished with 3 missing E-rings and 1 missing washer that held the buttons in the case😂
Hi Tarou Yamada ... Thank you so much for taking a moment to say you appreciated this video. Your comment about the work on the DW-2500 made me chuckle! Thanks again. Richard
Terrific!! Epic tear down, service and rebuild. I have this model of G-Shock in black, which I have mildly modded with a khaki bezel and Suunto strap which is much softer and more comfortable than the standard one.
Anyway, you have inspired me to dive deeper into the watch and apply white lume to the hour batons, this should lift the watch visually and improve it's already excellent usability. Looking forward to your next project, thanks for the detailed video for this G-Shock tear-down.
Thanks for the feedback Larx and very pleased this has inspired you to dive deeper yourself! Richard
Great video, and I too have always wanted to see what's actually in the back of these pieces. Brilliant Mate!
Holy crap balls Batman, I live in Sydney and by my standards, you went to a really nice beach! Excellent.
I used to scuba dive. After you've been to the beach it's extremely important to wash everything made of metal in fresh water to remove all traces of salt. In this case where it has a plastic over shield, leave it soak for half an hour with occasional agitation.
I would have been tempted to use a little rust converter on the rust stains. About 5% phosphoric acid for about half an hour. You can buy 85% food grade phosphoric acid and dilute 1:16 with a little distilled water. It does tend to leave bare steel with a blue/black patina (iron phosphate) but doesn't touch coatings (your mileage may vary). The bare steel can then be retouched with a little enamel paint or recoated to prevent further corrosion.
Hi Chris .... Yes my post salt water drills could definietely use a little improvement. Thanks for the tips on anti-corrosion, useful for these to be in the comments for everyone to read so thanks for that! Richard
I was wondering how on earth did the caseback rust in a year or two but salt water would do that indeed if not dealt with properly..
I wonder what that would do to the buzzer that's glued to the other side of the back plate though.
Just a tip for most analog-digital G-Shocks, press and hold the set button (top-left) for 5 seconds until it enters the hand adjust option. This allows you to “zero” the analog hands so they correspond with the correct digital time. Press the mode button (Bottom-left) to switch between the main hands and sub dial. Use the right buttons to move the hands position to get them back to zero. Press the adjust button (top-left) to exit this mode. This should be done every time there is a battery change, or if for whatever reason the hands don’t match.
Hi Neal... Thanks for this. I actually misaligned the hands a little ( in relation to one another) so I went back in and sorted that out. Then i read the manual and used the facility you describe to sync the hands with the digital read out. It worked very well. Good tip. Thanks so much l. Richard
Most higher end Casios have a "touch movement". This is Casio-speak for actuators on the hand motors that let the watch know their exact location. This is why they need to be adjusted after a battery change.
Also the buttons on G-shocks have dual gaskets instead of the more normal single gaskets, which makes water ingress unlikely. This also means the buttons are large.
a big help for a newbie like me...👍👍👍🇵🇭
I’m no fan of G-Shocks but that black and yellow one of yours looks pretty badass.
I love the look of your new Major "in the white" stainless steel! Maybe you could show us a little of putting these (or the next batch) together in a video.
Je vous remercie pour cette vidéo très instructive ! On est loin du charme et de l' élégance de l'horlogerie " classique ", avec son étalage de l'ingéniosité humaine et je n'aurais pas été plus avant dans l'étude de ce genre de montre, sans votre travail !
Interesting. Straightforward and really instructional guide for electronic watches. I can now do my G shock. The furthest I got into it, replace the cell batteries. Thanks
What's the difference between recklessness and courage?
Success. Well done, Major
Very interesting. I thought for a moment that you had forgotten the markers. I have to say that, every time I see your Major watch, I can't help thinking of Faulty Towers...
"Faulty, is that you?"
"Yes, Major."
Hi Eugene .... Good to hear from you! Haha! Faulty Towers is such a classic! Richard
I can't believe i just watched an entire video about disassembling and cleaning a watch... 😳 🤣
Satisfying!
Good so see another video Richard, has been a while....👍
I really enjoyed this. Thankyou
Wow so much patience and Skill. There’s something about you folks working on Watches, all those tiny Springs were making me nervous lol. Can you open up and clean a Gravitymaster GPW-2000. I liked how you gave the Coordinates of the beach at the end lol.
Most watch nerds love their G-Shock watches. I have mechanical watches that I wear to church, but the other 6 days of the week is my Casio. Ex-military man myself. The watch I brought with me when I went overseas, was my trustworthy G-Shock. The Japanese are to truly be admired for there contributions to the watch world. I also greatly admire the Seiko Spring Drive. Can't afford a Spring Drive right now, but some day...
hello from a wet and windy Swansea on shore for a change ( and not enjoying it ) great to see some else from South Wales has taken to this hobby Im still picking up watches from free sources to play with
"My G-Shock is going to smell so good ". 😂😂 Reminds me of your un- boxing
of the Invictor pro-diver when you "sniffed" the box .
Great video as always Richard. By chance I was in Pembrokeshire last weekend visiting MHCG & one of the coastguards on duty was wearing the exact same watch ! I'm now looking to ad this one to my growing collection of Casio watches, my first being the vintage classic A203 Blue Thunder received as a present in 1980 which is still going strong !
Looking forward to your next video.
Hi Simon ... Comforting to know that the folks at Milford Haven Coast Guard are discerning about their watches! The Coast Guard and RNLI are important folks and always pretty busy down here. 'Gingers' is the place a nice coffee and cake in Milford ... I find myself in there quite a lot! Richard
I thought these geo coordinates at the end were this beach 😁
P.S.
Very nice video, something different.
I saw that too. Is this an Easter egg or a typo?
I really enjoyed watching this Richard....29:12 looked like "I think I'd better look at the manual" moment there. :-)
Good to hear from you Station Plaza! Yes... And thats precisely what I did via a pdf from the interweb! So pleased you enjoyed this one. Richard
I have trouble setting the time on a G shock never mind taking one apart. We'll done.
You'd think a watch of that nature that may find itself in salt water on a regular basis would have a stainless steel case back?
On most G-SHOCKs those springs go flying when you take the metal backplate off. Most are a connection to a speaker on the backplate for the alarm and button push sounds. If you lose one a truck is to find the correct size lug bars (shock absorber looking things). Pull them apart and get the spring out of them. Cut the correct size length off and replace into the hole it came out of.. Put your backplate back on and voila. Your alarm and button sounds work again. They won't be brass but they still conduct electricity and work just as well.
I really enjoyed this video, and btw, a very nice watch.
well done... Just one note... That is the hour hand hasn't been placed exactly, in terms of direction, where it should be.
Hi there! Well spotted... I went back in and sorted that because it was bugging me. Also used the facility to sync the hands with the digital read out. Thanks for the feedback. Richard
Opened loads up over the years, I'd have scrubbed that back clean before opening though :)
Hi maxmixer! Yes.... Maybe that would have been the best way to go! Richard
Very nice and superb video thanks for your efforts appreciate !
Such is the engineering marvel of the Casio G-Shock that even watchmakers who works on mechanical watches own one.
I didn't like the way the G-Shock looked in the jeweler's case or the way it looked on my wrists. Now that I see what it looks like inside, I like it even less. Great vid.
And BTW, I like the Major
Hi Abe ... Sure, these watches are not for everyone but I am a fan and I know lots of folks are too. Thanks for the feedback and saying nice things about my video and watch! Richard
@@richardperrettwatchmaker sorry for not clarifying that I was only talking about my own personal preferences. Still a great video though. I wish I knew how to fix watches. It'd be a fun hobby.
I have the green one. Terrible to read and to operate, but very cool. I will remember this video when I need to repair it, although I don't expect that I will ever need it ;). Nice video.
You've probably found out by now but the SW batteries are for low drain watches with no backlight, alarm etc.
Your G-shock (and my GA2100) both need the SRxxxW style of battery.
Hi, Richard. Did you do something relataded to watches in army? I'm curious.
Hi... Not at all. I was involved more with tanks! Our tools were a 'a bit chunkier'. Richard
Excelente créame que nunca, dudé ni un poco de su capacidad maestro,,
Felicidades fue una experiencia muy
Emocionante , bendiciones
Very educational and entertaining video. Being on a fixed income, I can't afford a Casio G-Shock so I wear my Rolex everywhere.
Lol.
That cover plate should be stainless steel grade, if it's plated metal that's a sad surprise 😮. Amazing 👏 only for watch makers most users would end users up destroying it. Well done your a professional. 😺
Very interesting video and a pleasure to watch. Thank you!
Thanks David! Very pleased you enjoyed it! Richard
I think there is a hand alignment mode on the Casio analog watchs. No need to take them off of realignment!🤔
Hi ocean Zu ... there is! Hands on this movement are not independent so I had to go back in and correct the relationship between them but then I used the hand alignment mode to match the digital time. Useful! Thanks for the feedback. Richard
u can set the mode wheel in the whatch settings by holding the adj button for 5 secs
Great video, I am curious about the motors, they look like Lavet-type stepper motors (single coiled attested by this exceptional video), but Lavets usually are unidirectional, In this watch it seems Casio used Timex like step motors, which explains the difference and somewhat lagged hand movement result in the natural steps onwards versus backwards, FYI US patent 4205262, it's referenced by thus 1988 European patent application by Timex. This for sure will be a matter of discussion always about the cost versus engineering delivered from Casio to its customers.
Wonderful. Thank you very much but the one important question . . . !
Is this G-Shock tougher than say a Rolex - if you threw both watches against a wall - multiple times - which would survive longer?
In every day life - slaming a spade into rocky soil gives an automatic watch massive shocks and breaks some watches . . .
I tried diging with an older watch which then needed repairs . . . I now have a G-Shock 2100.
Would love to see a video on the 2100 series or even the later version with solar charging.
The other beauty of these watches - parts can be changed - I like the idea of a bespoke watch!
Would you be interested in adding bespoke parts?
At the moment sorting out the movement and a more attractive strap - would like to enjoy wearing the watch
Many thanks for the video,
I love my Citizen Attesa CC9015-54E. It’s an all-analogue display, with a titanium body and bracelet, anti-reflection coated sapphire crystal. It receives radio time signals and so is always correct to the second, it has GPS so on foreign trips it automatically adjusts to the correct tine zone, and it is charged by light, so no battery changes needed. Yet it’s really light on my wrist because of the titanium.
I was very surprised the case back wasn't stainless steal.
Very brave indeed!
The little spring is for the sound off the watch. Without it, the watch will work, but you will have no more sound.
I love Casio. To me it is the new Rolex. I own one of the cheapest & wear it with pride like it is the top of the line. Some day I will own the top Casio. You have done a great job.
It is a good man that will admit when he has made a mistake and not try to cover it up.
The first gshock I disassembled , I destroyed. Sad. But a lesson learned the hard way.
Hi Mac4Willy ... yes, it was touch and go for me a few times there and I do this kind of stuff for a living! Richard
Hi Richard
What Gshock model is this watch? It's very nice
Cracking video Richard thank you 👍
Thanks bigun635! Richard
@@richardperrettwatchmaker I sent you a message a while back on insta, have a gander if you get chance 👍
I have a G-Shock GA100 which I bought ages ago from Argos for £40 because I needed a watch at work right there and then. I absolutely hate everything about it, the way it looks, the way the hands always seem to cover the display when I need to see something on it. But it just won't die, and I've worn it on and off for years. Much better watches that I loved have come and gone, and at the moment my Traser has stopped, my Luminox needs a new movement and my Tissot's crown has fallen off - so I'm back to using this G-shock at work that I can't stand but just seems to be indestructable, despite being abused and having not a single days service in at least 15 years.
Agricultural, that's a good description!
Hi Richard. Leaving the corroded back plate unprotected in seawater is not a good idea. I would consider a rust inhibitor and/or a thin layer of silicone grease.
Way better video, when you are telling about the process. The rolex bling video was getting me sleepy 😴. That's sometimes nice, but I'm sure that's not what you are going for 🤣👍
Brilliant!
How do you dispose of contaminated cleaning fluids?
Trabalho feito com perfeição parabéns
Você é fera.
I reckon that cleaning solution is pink shampoo brought back from the Hotel.
just curious if you know anything about watches with a fuseé mechanism
i had a gshock. wanted one for years. when i finally was able to buy one i regretted it very quickly. once on my wrist i found i could not read the dial easily. i would buy another if i could read it.
Great video as always Richard. Here's an odd one for you. Would you mind explaining (if you haven't already) the meaning of your family crest? Something to do with jewerly... gold.. watchmaking? I'd be interested to know. Cheers from Canada!
Are the drivers you're using Phillips or JIS?
Gee, this is a really nice G shock
Yo tengo el mismo reloj.es un reloj increíble. Saludos desde Chile 🌶.
Now you have the opportunity to make your Gshock one handed.
Great video!! I had a ga-2000 but stripped the threads in several holes (for the caseback and rear guard) when changing batteries, so no chance of resisting water afterwards. Luckily, I found a used replacement in good condition. What can I do to avoid the problem when I come to change the batteries next time? I thought about pressing the caseback down while unscrewing, so the screws weren't under as much tension, but you didn't do anything like that!? Was I just unlucky?
Why the watch industry does not use Phillips screws?
The hands aren’t aligned….that would drive me crazy! Otherwise that was perfect!
Hi Brandon... Yes I had to 'go back in' and re-align them! Its amazing what I miss sometimes when I am so focused on the filming and less so the watch! Thanks for the feedback. Richard
12:14 is that a Xperia?
Hello, very interesting and instructive video, thank you very much however why make a comparison of a G-Shock at less than 80$ and compare with a watch of 10000$? Of course the materials and workmanship are not the same. Wouldn't it be more reasonable to make a comparison with an MRG-B2000GA-1A for example to get a real idea of Casio Premium?
Anyone know where i can get assembly diagrams for GA100 and also spare parts
thanks
please try a mrg next time, to see whether the mrg craftsmenship justifying her insane price tag.
carbon composite case contains several sensors
My partner is a Casio / G-Shock dealer - and they are not a great company to work with (in the words of my partner - a bunch of shits) - normal watches can have their batteries exchanges easily in the shop, these are more of a challenge and customers do not like to be charged extra - further if you want to sell other models then they are not flexible at all.
I wanted to purchase a casio watch for personal use and they said no ( and yes I would pay for it)
It now looks as if they will only sell on-line in the future
Thanks for this content really helpful . new subscriber
I'm waiting for my ultimate G-Shock still; analogue, no complications beyond a date, good lume (or a maybe a light) and solar powered so battery changes are unnecessary
a springy, tiny, magnetic component?
24:08 What is the mistake?
Yup
bro make a video on garmin tactix delta
And I gave up just trying to change the watch bands on one of my watches
Nice to see for entertainment value but pulling apart a G Shock like this is asking for trouble, we don’t really service them in the way you will service a mechanical watch, most parts are unavailable anyway, at best, if you are lucky can find a whole movement for it.
Hi Armand .... Very pleased you enjoyed this and yes this video was primarily made because I figured folks would find it interesting. I know I did! Thanks for taking a moment share your thoughts. Richard
I've had this watch, and sell it a couple month ago. And now, I feel sorry while watching this video
I suspect it was babied there after.
Hola.
No sé porque te obstinas tanto,comparándolo con un rolex.
Sabes muy bien que es un reloj de distinta concepción.
O solo es criticar a un producto japonés?
Saludos.
great video. it is hilarious after this amazing (and humble) display of techinical prowess, when you show the one on your wrist its wrongly set.. very funny.
I have the exact same watch in the same colour combo. I wanted an indestructible watch that I can swim and use in the gym etc without worrying and g shocks have done the trick for years. I’ve got Raymond Weil, Seiko etc but literally never use them. I just use the g shock.
Surprised how much corrosion there was.
Very disappointed that they didn't put stainless steel inside this watch
i'm not likeing how dirt accumulates between those plates 2:06, that will then keep leaking dirty water to then skin after taking a shower and cause fungus infection and smell. i think i would rather have another casio watch without that second plate.
🐈
Done in true British 'bodge it in the shed' fashion! Captivating and cringe-inducing at the same time. By the way, what bit did you forget to do on the reassembly? You didn't show or tell the answer..
