G-SHOCK versus Watchmaker

www.majorwatches.co.uk/sea-wo...
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.

[@RedDogForge]

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.

[@michaelholevas9385]

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.

[@EvilUnderTone]

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.

[@KarunaMurti]

I believe the limit is 2039, when the calendar reaches its limit. Newer gshock limit is 2099.

[@joselitojuera3120]

[@WrightsW5]

It's great to see a proper watchmaker working on another form of proper watch that millions of people own, digital, without being stuck up about it. Great video.

[@TheChiraagG]

What's crazy is I've been playing around with the inside of G-Shocks since I was a kid. Not to this extent, sure, but just to open, clean, change batteries, reseal, fit new springs, fix poor button connectivity etc. I would struggle with mechanicals I'm sure of it., I always used to outsource those repairs. The work done here is pretty intense for my abilities! P.S. I've actually replaced those pernickety springs with trimmed springs from spring-loaded pins and the watch beeps have been fine!

[@tonioreyes]

So you have watched another channel? Because when opening the watch there was a lot of sand. Instead of cleaning it first, he opened the case, so sand is in the watch at that point. After that, he turned the movement upside down with sand on the case. I would not let hem near any of my watches, ever!

[@nealstacy4393]

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.

[@richardperrettwatchmaker]

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

[@gmtoomey]

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.

[@joselitojuera3120]

a big help for a newbie like me...👍👍👍🇵🇭

[@alexdeleon7135]

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!

[@richardperrettwatchmaker]

Great feedback Alex! Much appreciated! Richard

Hi Patrick ... Yes it was a bit of a 'journey into uncharted (by me) territory'. I thought it would be fun and folks seem to like it so very happy with that. Richard

[@larx4074]

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.

[@richardperrettwatchmaker]

Thanks for the feedback Larx and very pleased this has inspired you to dive deeper yourself! Richard

[@theronwolf3296]

Lot of fun watching this. I've changed the batteries in my G a couple of times, but never went that deep into it. One thing, at the end when you are trying to get the mode wheels and hands properly linked... in the Casio manuals for the specific module (available for download), there is a step by step procedure to get everything properly aligned without physically working with the hands. It's different for every module, but anyone can resync without even opening the watch.

[@Gzeroy]

A couple of months back I opened and stripped a G-Shock completely. It is really interesting to see how small the actual movements are,on the these modules, each smaller than the battery, and how tiny small the motors are. They are smaller than the smallest screw on the movement.

[@neelsengupta662]

Nice video from a pro perspective. I did the same with a Timex Ironman 8 Lap from the early 90’s (?) and it really reminded me why I truly loved that watch. Great watch for working out and outdoor activities. I wouldn’t sell it for anything.

[@UnholiestJedi]

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!

[@richardperrettwatchmaker]

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

Thank you Richard for another watch anatomy class. Always enjoy the quality of your shots, your steadfast hands and clear narration in every video. So got me curious if you film, work on the watch, and narrate simultaneously. Or you just focus on filming and working on the watch, and dub your voice during editing? Anyhow really enjoy all facets of your videos and hope you will find time to produce more great comments and your Major watches.

[@raycollington4310]

I enjoyed this video. As someone with a host of the usual Swiss Rolex, Breitling, IWC watches, since retiring I now have four G-Shock watches. The MTG-B1000, GWG1000 Mudmaster, GWN1000 Gulfmaster & GPR1000 GPS Rangeman. They make great daily beaters IMO and I love not having to worry about damaging something expensive.

[@richardperrettwatchmaker]

Hi Ray ... I think Casio have done something very clever with G-SHOCK because these watches seem to transcend the whole of the rest of the watch market and have a following amongst luxury watch enthusiasts and folks that are really just interested in G-SHOCK. Thanks for for the feedback which corroborates this view! Richard

[@JAMESWUERTELE]

I wear my GPR 1000 all the time! I need to charge my 10 others lol.

[@joshwarrey3728]

Those models are still expensive but not obscenely expensive.

[@edwardmurphy8622]

What an interesting video. Thank you! Nice to see craftsmanship in any form. In case it is useful to know, the central protruding spring which extends beyond the insulator on the back of the circuit board is to connect the watch electronics to the piezoelectric speaker for the alarm noise. This speaker is visibly mounted on the inside of the metal watch back. I don’t think the spring has any other purpose. Putting the metal back in place may have further compressed the other non soldered electronic connections or the zebra connector against their contacts to make the electronics fully functional. It was unlikely to be related to the spring I think.

[@gromit1996]

Fantastic to see the level of miniaturization that casio achieved on electromechanical parts. Just some comments, The Spring on back is to make contact with the piezoelectric speaker attached on inner face of back metal plate. All g-shocks have same approach to electric ans mechanic connect the speaker. After the change batteries it is also necessary to enter on hands alignment procedure as described in owner's manual.

[@SpikeXtreme]

Thank you for the follow up video to your purchase of the Carbon Core. I used to have a large collection of battery powered G-Shocks but always dreaded the battery change. I now only own the solar versions because i could never test water resistance after opening the back. G-shocks are a wonderful range of watches and i wouldn't want to wear anything else to work.

[@drain7738]

That's exactly my thoughts and with solar it should be years before a battery change is needed

[@Chrisamic]

Have a look at the Chinese pressure testers. They are about a tenth of the price of the Swiss made ones and do precisely the same job of testing to 3 atmospheres (the swiss standard). That's all most testing is done to, unless it's for industrial purposes (like actual deep dive equipment, which is extremely rare). It's a pretty safe test. The watch sits on hanger in the tank above the 300ml of water which you put in there. You then pressurise the cylinder to 3 atmospheres (most dials go to 6 max but there's really no need). After about a minute you then lower the watch into the water and slowly let the air out. A leak is indicated by a significant stream of air bubbles coming from the watch. A little coming out around the bezel is normal.

[@ianjamieson3985]

@@Chrisamic Hi Chris, I never thought if actually being able to afford pressure test equipment! What site/s can I get one from and roughly how much do they go for?

[@Chrisamic]

@@ianjamieson3985 I got mine from Ebay, AU$270 including shipping, and I've been using it about a year so far. It's one of those things you use occasionally, but no other tool can replace it. I charge $20 additional for pressure testing (clients choice) so it has probably paid for itself a few times. I think all the seals and 0-rings are standard parts so it is probably serviceable if it ever needs it. At that price it's easy to justify the purchase.

33:23 actually you can do the disc adjustment with buttons combination (I forgot which buttons, but it's in the manual) Because the disc will slightly misaligned sometime if you drop or bump the watch (it's outdoor watch, so that to be expected) It's good that Casio provide a solution to aligned the disc (and the hands too) without having the user to open the case, they know we will abuse the G-Shock

[@richardperrettwatchmaker]

[@d4diecastsales796]

Probably a good idea when you noticed the sand and dirt under the yellow case back would have been to stop and brush it off/ blow it off before opening the watertight seal. Some analogue g shocks also have the ability to set home points (with a series of button presses) for the hands and wheels, most likely in the instructions.

[@sashodasho]

Appreciate the care and precision you bring to this watch. A guy on one of the G-Shock channels attacks his watches with a battery operated screwdriver.

[@Chrisamic]

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.

[@richardperrettwatchmaker]

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

Fascinating video. I am amazed with the quality of a simple G shock watch. It would be interesting to take apart one of the more expensive Master of G models like the Frogman GWF-A1000 or a really high end Oceanus model wihere the fit and finish of the case is similar to Grand Seiko watches.

[@markiangooley]

When I see that those supposedly 10 seconds per year ETA PreciDrive (thermocompensated quartz) movements have jewels (3 to 8, depending on the model), I’m always of two minds. Part of me is saying “quality!” and “it can be serviced!” and another part of me is saying, “I paid under US$200 for this Certina watch new, though the list price is far more, and service would consist of replacing the movement with a new one that’s $65 retail, so wouldn’t I be better off with a no-jewels movement like the one in that solar radio-sync Citizen watch I wore daily for ten years and still occasionally wear?” If a watch is quartz-based and too cheap to be serviced (barring sentimental reasons such as being Dad’s), are jewels just points of failure? Maybe? I’m stunned that the G-Shock case is so leaky! It looks as if it’s impervious but apparently it’s only as good as it needs to be… or rather, the delicate innards are safe behind that gasket, but the outer portions of the case are free to accumulate water and dirt in small doses.

One thing you missed, is that the pushers come out too. Behind the button they have a cavity where their return sprint lives. This place collects a lot of gunk too and here it'll affect the feel of the pushers too. They also have tiny O-rings that can benefit from a bit of grease. Having that centre spring electrically floating isn't a problem to these modules, it only handles the beeps. What was probably happening is that the light pusher pushed the module out a bit, preventing it from actuating. Usually these watches have a reset contact point, which you should connect to ground (the metal module frame) for a second after a battery change. You can probably realign the wheels in software as the stepper motors have no way of keeping track of position and can drift when turning while receiving shocks. It was cool seeing how incredibly well-built these fancier G-Shocks are. I've dug DEEP into my GBX-100 in my modding adventures with it and it's nowhere near as well put together. Same with the few cheaper non G-Shock Casio's I've taken apart, but all is relative as they stand far above the other cheap digital brands.

I’m no fan of G-Shocks but that black and yellow one of yours looks pretty badass.

Great video Richard,, I damaged my gshock that I wore for work, years ago, just trying to change the battery,, ha ha,,, so my recent purchase, is a solar Gsteel, which hopefully, I'll never have to open up, with my clumsy sausage fingers,,, lol.. Interesting that the screws on the bezel are "dummies"... All the best,,, John..

[@richardperrettwatchmaker]

Solar GSteel is such a good choice! I am a little envious of that and yes it should just go and go for years. I was a bit supprised about the bezel design too it is super quick to put on I guess so makes sense for CASIO in production terms. I expect the MRG designs is more traditional! Richard

[@markiangooley]

For ten years I’ve worn (mostly) a solar radio-sync Citizen and… went through five leather straps before buying a cheap steel bracelet. Maybe the capacitor will die someday. Now I own a few more watches and perhaps someday I’ll ruin one trying to change a silver oxide or lithium cell…

[@juliocazares]

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.

Really good long form video thanks. I do have a question: how do the smallest parts in, say, a Rolex compare to the smallest parts in your G-Shock, in terms of size ?

[@mikeoreilly4020]

Brilliant!

Trabalho feito com perfeição parabéns Você é fera.

Love GSchocks. Insanely good watches for the money. Cheap and cheerful GA 2100 is my favourite. 2nd favourite after my Seiko PADI Try a drop of ACF50 on the corroded back. It will remove the corrosion and arrest it from getting worse leaving an ultra thin protection coat in place

[@gigglybears]

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?

[@michaellong4813]

I just got this model in the same color. I love the model but the black/yellow is exceptionally attractive to me. Great salesmanship!😂

[@thego-o-dstuff1036]

A very professional disassembly .

[@paullangton-rogers2390]

I've never seen such an immaculate workshop even his tools are colour coded! You should see mine Richard (or best you don't) and I'm not a watchmaker like yourself who I hold tremendous respect for after having a go myself at repairing a vintage watch (how hard can it be, right?) and having springs flying out everywhere and a bag of 30+ parts for my trouble. To me as someone who has designed and built computers and written software, watchmaking repairs is akin to performing open surgery on a living patient. It's that hard and technical, you need very very steady hands and astonishing skills. I really enjoyed the story of the watch and seeing the repair process anyway. I'd be exactly the same if I was Rolex to be fair, a big brand of extremely high value with a reputation to protect you stay well clear of products which have been fitted with non-Rolex parts . So that makes Richard BETTER than Rolex for still taking on the task! I did wonder if the watch might be haunted or something paranormal going on, a watch running so fast losing 4 hours a day is quite bizarrel.....alien abduction of previous wearer?! lol I have some watches and clocks over 100 years old still keeping good time if regularly wound up properly that have never been serviced in decades.

[@LollipopUnicorny]

36:24 that wheel spinning looks pretty cool

[@adrianw3985]

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...

[@michaelhazen3153]

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.

Would you be able to do a restoration video on a seiko 6602, or a seiko 7a38 if possible? Please
