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.
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.
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.
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.
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!
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
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.
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
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!
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.
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
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.
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.
@@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?
@@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.
A good story sometimes ends where it started, glad to see the G shock made it back to the beach. More G shock content of this caliber on RU-vid is needed
This is a very interesting video Richard. Although I don't own a analogue/digital G-Shock watch I do own two 5610 radio controlled/solar powered G-Shocks. I have always wanted to see the inside workings of them though. One day I might get an analogue G-Shock but I wouldn't want to do what you did in case it never worked again. Thanks again you are amazing 👏
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 👍🏼
As a newcomer to Casio G-SHOCK really enjoyed the video . I have an omega planet ocean quantum of solace watch which was never of my wrist from 2007 until he stopped in March this year . It was sent of to omega for a service and still not back 4 months later I needed a watch so got a Casio mud master which is an amazing watch but then started collecting G-SHOCK up to 5 now and stopped chasing omega up to find out when it will be sent back might even sell him as I have my eye on a few more and my girlfriend in on the act now wearing babyG which gets for more comments than my omega ever did . Thanks for the video will start watching all videos now a subscriber many thanks phil in Blackpool
Lol im with you have a couple of omegas too, same on the plannet ocean. Started off with basic mud master, built up to maharishi yellow strap version, red strap version, earth and acionn, mananged to ge t a frogman icerc,, love it for the colours,, love them, deffo collectable,, keep your collection, going
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.
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
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
Hi Fajar! Good point sir! And yes I used this facility when I went back into the watch to correct the hand misalignment that was apparent when I had finished shooting the footage. Thank you for taking a moment to highlight this to folks reading the comments as it is a useful point. Richard
That was an enjoyable journey into the unknown. The fact that it was your first time entering the G-Shock allowed us to follow your method and thinking and also discover as you did, in real time together. Thanks 👍
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
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
Wow !! This video is so interesting, It could be a reference to repair G-Shock watch ! So nice job Mr. Richard and of course thank for sharing ! Happy to see you on the channel again !! ✨👌
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
Nicely done! I came upon your video and since I have the same watch in all black I was excited to watch. I would have never thought there would be any debris inside. I thoroughly enjoyed watching this. Thanks for sharing it. 👍🏻
Thanks for this video! Absent of your watchmaking skills, a dirty and water-damaged G-shock would be unceremoniously introduced to the bin. I thank you for granting new life to at least one. But if you're going to clean and rehab one of the watch world's more economical brands, that "1965 Seiko-Matic with the dodgy bracelet" is absolutely entitled to some love!
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.
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!
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!
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.
I worked in the security industry and wore a G-Shock all that period. It was great as it took the knocks of hard everyday outdoor wear. Any other watch would have shown the scars of commensurate environmentalist age but not so the G-Shock. Most military and p0lice wear them as well, because G-Shock takes the heavy and often outrageous nocks the outdoor activity.
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."
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.
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.
Hi Greg... Seiko Twin quartz is such a discerning niche sir! These are really excellent watches... be prepared for tiny pivots in the low torque power train. Enjoy! Richard
@@richardperrettwatchmaker thanks, Richard. I've spoken with two watchmakers about having my 9943-8000 serviced. One told me it would be a waste of time and money, the other said anything with a gear train should be cleaned and oiled after almost 45 years. Have to say I'm in agreement with the latter.
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.
I should have known that a former officer would be concerned with timekeeping 👍. I have several Gshocks dating back to the eighties - my latest solar has been going strong for 14 years and counting.
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.
I remember have a G-SHOCK in my old teen times, but nothing compared to this one. Omg that tiny piece... i really listen you say "little..." (for the piece) but i didnt think was SO little hahaha
Richard your macro photography is really good! Thanks for the video, I own a number of G Shock watches and battery changes are about my limit of being comfortable taking one apart. Cheers from Nova Scotia…MikeR.
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.
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...
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.
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..
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
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…
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.
"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
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
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.
When you restarted the watch it went to alignment mode. When it was flashing "sub" it actually meant that you could then align the sub dial to the proper position and pressing mode button once would take you to main dial which said "0:00", which meant that you at that point can align the hour minute hands. No need to open the watch and align those dials manually. Sorry that my explanation is not perfect but you could look at other videos on how to align gshock dials, you'll then get a clearer idea.
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.
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
