Hello Perth Watch:
I would like to thank you very much for the extremely clear video. I needed to change the battery on my Casio G-Shock DW-9050 (2163) and thought it would be straight-forward. I removed all 8 (4 lug + 4 back) screws; removed the back + gasket and then the rubber "buffer" plate; and...was completely stymied by the metal clip holding the (single CR2016) battery in place.
I searched Google for instructions, and a few videos were not clear at all. Then I came across your video…perfect.
Your instructions on how to use a pin to “unspring” that metal battery hinge were truly a lifesaver; they were very clear. Within a few minutes I had replaced the battery (Renata CR2016); re-installed the back and the lugs; set the time; and the watch is running perfectly! Not bad for a 25 year old watch!
Again, thank you so much. Your instructions are so well done, and your contribution is fantastic.
Best regards, ciao,
Tomaso.
Thank you very much for the kind comment - I am very happy to hear that this has been helpful to you. This is exactly why I thought to put up this video. Cheers! :)
@@PerthWAtch Hello, Yes, the video was incredibly clear and helpful. Not many videos are that precise, and that precision is so key to us non-experts. Really well done, and your comments back to people who post here indicate also your humanity. Your work is truly an asset, and given the the time it takes to produce and post is no small favor. Best regards and cheers to you as well.
a friend gave me his old ProTrek yesterday, it was made in the 90s, have ordered the 4 batteries costing a total of around $5 ... looking forward to replacing them and bringing the old thing back to life (not my friend, i mean the watch, my friend is doing fine, haha, don't worry) ... loved also the exchange between the two of you, it's amazing what things we learn in life, good luck, Tony, Glasgow :)
@@tonycassidy4112 Rest assured the process is fairly simple. Just be a bit delicate when lifting (with a pin or very small tweezers) the little metal clips that hold the batteries in place...starting at 04:55 in the video...the same process on a 1-batt or 4-batt watch.
That done, the rest is incredibly simple. Just disassemble over a catch surface of some kind as some of the screws are really very tiny. Again, the video really is extremely well done and so clear. Thanks much to Perth WAtch.
I am having good results with Renata batteries, fwiw.
Best of luck and stay safe! Cheers.
@@venessian8579 thanks for the advice Tomaso, that's very kind, yes you too, take care and stay safe
Good useful video 👍 strangely enough I enjoy changing batteries for family and friends thanks Ivan 😁
Thanks - haha strangely so do I! :)
The Casio Pathfinder PAG 40 is very similar to the Pro Trek shown in the video and it is very easy to change the 4 batteries. It follows the same procedure as the one you showed. Thank you.
“Very easy” is subjective… some people would not go near this!
Thanks for this, I have a 1470 and had the batteries changed at my flea market, he said 2 batteries and I thought it was too expensive at $15 but am loving the watch.
Now I know how to do it myself, even though a different model. Thanks from California.
Cheers mate, glad this was helpful!
Very nice and useful.
If I may add one thing, sometimes after battery change the watch is still off. In that case all you need to do is stick a needle inside the hole in the middle of the back metallic part, usually indicated by an arrow! Thanks
Thanks - yes you're right, sometimes you need to do a little "reset" after changing the batteries on these things.
My watch is still not on after putting a pin in a hole that was just off the middle
@@deeoverthesea1 you need to touch two points - look for the "AC" hole, use a stainless steel tweezer or paper clip (change the shape to a "V", insert to the AC hole (you can see a gold surface) and touch the back of the battery (+) terminal. Both end will need to touch these spots so the watch can reset. touch for 3 to 5 seconds and your watch will be reset and you should see the display showing "12.00"..
@@kuthsith4128 This advice is commonly offered but always raises more questions: eg of the 4 gold terminals, do you touch each one separately, jointly by shorting all to one another and is the tweezer or paper clip earthed?
@@Maxadolf exactly, whatever it is used (tweezer or paper clip shall be earthed) missed that point there.
Never seen so many batteries on a watch. Always a good idea to use silicone greese on the rubber gasket before putting the back on. Keeps the rubber supple and watertight
Yeah good point about using silicone grease on the seals... guess I should look into getting some!
@J CAT05 wow. Impressive.
very helpful. saved me a lot of hassle. thanks.
Most welcome :)
Good tutorial. The only thing I do different is that I put on a pair of gloves when I handle the batteries so I don’t leave any moisture from my fingers on the batteries. I don’t know if it helps or not
Yeah probably does help particularly if one has sweaty hands or if it's quite humid. Thanks for that! :)
Great video.
I replaced the battery on a G-Shock DW-5600-1E. It was successful. Take your time and see if yo can find a tuitorial for your model.
I tried doing it on a Casio F105 and bend the retainer cl p so bad a had to throw the watch away. Luckily it only a $17 US watch. With a really low end digital watch the battery could cost almost as much as the watch.
Thanks for that - yeah if you can find a video of your specific model, all the better!
I love how adjustable every hand is on the shock watches, so simple to synchronise everything perfectly with the digital display on my mudmaster after replacing the batteries
Yeah that's part of the convenience of digital G-shock :)
Thanks Ivan...Wow four of them in one watch! I like the tip about the Renata batteries.
Most welcome man - haha yeah, this is most I've ever seen :)
*You saved my watch from being jumped on, burnt and hit numerous times with a hammer.*
I'd gotten to the bit where all the screws and panels were removed to expose the 4 batteries. So out came the instruction manual... And after a quick look through that in every language it provided, I was back to square one.
*How the heck do I remove the batteries?*
So my watch says _"Thank you."_ for still being _relatively in one piece._ Even though it's actually in 13 pieces if you include the watch, plates, rubber seal thing and the 8 screws! The 4 small screws on the side of the watch are in two different types. Currently as I look at them, I can't remember which holes they went into 8-((... Oh! Well... _C'est la vie..._
Time to order the batteries and hope the bugger still works. It's been dead for... I don't know... 15+ years!!
Haha great to hear that mate - I hope it all works out once you get the batteries in!
Thanks I just picked up a Sea Pathfinder I'll be doing this tomorrow
Never heard of that one - interesting combo of words!
@@PerthWAtch exactly the same module sf 40
Cool
Great video man🤟
Thank you :)
Your video was very helpful for me as I bought 2 of these watches recently on ebay from 2 different sellers. Both watches were dead and both seem to have the original batteries in them , as both watches batteries were made in JAPAN. The watches look brand new , no scratches , cracks or even any wear on the canvas strap. I was not able to get the strap off either watch , the screw just kept turning both sides of the screw. I tried another screwdriver on the other side to hold the screw from moving as I turned the screw from the other side, but the watch was not stable enough to do so. I wish you showed that step in your video. Looks like I might need to use some kind of jewelry vise. I also bought a Casio Protrek PRG-50 which was New Old Stock from ebay as well. Very similar to the PAG-40 watches , but with a Titanium band and Tough Solar , but it doesn't have the stopwatch function that the PAG-40 has. Thanks again for the video.
Thanks for that - I’m glad you found at least some helpfulness from the video. With regards to removing the strap, it can be very tricky. Maybe get another person to help you hold the watch?
By the way I used Renata batteries in both watches.
Great info BUT somewhat long winded. Inspite of that thank you.
Thanks - hope you found this helpful :)
cracking video, all very clear, thanks, Tony, Glasgow
Most welcome, glad it was helpful :)
excellent thanx
Most welcome
Cool...thanks!
Most welcome :)
One way I can always keep track of my screws is getting a piece of paper, draw a rough outline (maybe tabs for side mounts) of the stuff you are about to disassemble and taking out a screw you punch it through the paper. It keeps them from rolling away and keeps track of where the screws are to go and in which order.
That’s a good idea! Thanks for sharing.
I do this when dis assembling an engine. Its perfect all the time.
super gemacht
What?
Having so much trouble sourcing a replacement battery for a Casio protrek WSD F-20
Just hop onto eBay mate!
cool , mine will probably need a battery change soon
And now you can do it yourself! :)
Great video , I have over 100 Casio watches and G-Shocks and I don't think any of them use 4 batteries. My Casio ATC-1200 and my Casio PRT-40 use 2 (399) batteries. The others use one 1616CTL in the Tough Solar models and one 2016 , 2032 or 2025 in the Vintage Casio non-solar watches. P.S. I was always told never touch the new batteries with your bare fingers , this causes premature battery failure. Use plastic tweezers or finger cots. I did notice you didn't show how to clear out the watch after putting in new batteries. I use a paper clip bent into a U shape instead of tweezers. Then touch the AC (All Clear ) and the battery to reset the watch.
Thanks for that - wow that is a LOT of Casio!! I've gone through quite a few Casio in my time (not quite 100 mind you) and yeah this is the only one that required 4 batteries.
Thanks for the tip about not touching new batteries, I wasn't aware of that - are you aware of the mechanism by which that might damage them? I suspect this doesn't apply to other types like AA and AAA batteries?
Does the Pro Trek loose water resistance when opened?
Only if you don’t replace the cover back properly
Thank you. :-)
Most welcome :)
Thanks for the video, I followed the steps here but the watch hasn’t turned on. Could this mean the watch is dead or do you think it’s worth trying some more batteries? I used Energizer batteries that also happened to be in the watch when I removed the back.
Did you put the flat batteries back into the watch!?
much appreciated!
Most welcome, glad it was helpful :)
Hi Ivan I've just been given one of these. I removed the back etc and a small silver spring came out when I took the white plastic cover off. Any idea where it goes??
Yeah I’m pretty sure there is a hole that it belongs in - take a close look at my video and you should be able to spot the spring.
@@PerthWAtch
Many thanks. I'll give it another look 👍
I managed to break off the contact which connects to the sensor at 12 o'clock. Does anybody have any tips for reattaching this? I have some no-solder pcb repair glue which might be suitable? I also have a tiny copper spring, which came out of somewhere, maybe a button!!! Maybe I should have taken it to a shop.
I think best to post this question on a good forum.
This watch needs more batteries!
Hahaha, agreed! :D
Might have to change the batteries on mine as well. You have the SR927SW but there's also the SR927W which are the ones I found on line to replace. Is there a difference? I want to order the right ones
I think there is some minor difference in the make up but they can also be used... best do some research on this before ordering, apologies I'm no battery expert.
You are right! The Casio manual says that the SR927W batteries are the right ones. (Renata 399)
Thanks for sharing the video! I changed my batteries, and the screen is blank... Has anyone had this problem before?
What watch did you change the batteries on? If there has been a leak, the contacts may have been damaged.
Thanks for responding, the watch is a casio prg 40 QW-2271. I have change them before, and I have never had to reset it.
Hmm curious, maybe one of the contacts has been damaged?
@@PerthWAtch Thanks for your help, time to give it to a professional watch repair guy, and get off this lane.
you put the battery upside down.😆
Rechargeable battery?? Which do I need 🤔
They usually don’t sell the capacitors for solar watches… might have to check with manufacturer
@@PerthWAtch it needs CLT 1616
I took it out OK but two springs dropped out and now I don't know where they go no holes look obvious for them and it won't work without them lol ops Any ideas?
Search online or ask on a good forum I think
@@PerthWAtch tried online no luck so far and the online instruction book for watch doesn't even cover opening up for battery lol
I joined a casio fb group to ask. No luck lol these two bloody tiny springs dropped out of somewhere....one I think I even took out and thought I'll remember 😅😂🤣
You made a 2 minute video last 9:15 👍🏻
You are welcome 👍
I am surprised you have yet to review an Adina? I have had several & think they are great. Strangely enough, still not well known.
Actually haven't heard of them before... sounds I need to check them out! :)
@@PerthWAtch Please do, they are online and reside in Brisbane. I have owned 9 of their models (and counting). I only have a 16.5cm wrist and their Automatic 151's are the only (automatic) watch on the market that are small enough for me to wear (lug to lug is 43.5 if i remember). That is what got me into them, the rest is history!
My Protrek PRG 240 is showing low battery level, after 10 years. Does this model also needs 4 cells?
What does Google say?
Prg 240 battery CTL 1616 tough solar
If I put silicone Caulk on the gasket, will that make it water proof to 20,000 meters?
Yes
Perth WAtch Awesome! I crossed the wrong family so I may need my watch to be safe in extra deep water for a very, very long time.
Don't worry, it'll be fine
Hack for stripped screw heads: Screw Grab, works great
Interesting
Do gshock straps always rot/break?
After 20 years with heavy duty use, I think that's fair enough, and they're easy to replace.
On the other hand I do also have watches which I've not use very much at all, and the straps remain intact on those.
Hi Perth. during the battery change, I removed the steel bottom and turning the clock, a very small spring came out, and I don't know where it was positioned. Can someone help me? It is not one of the two springs of the ringer
Take a close look at the video, I believe you should be able to see the small hole near the middle wear the spring should sit.
@@PerthWAtch Thanks. about at which minute?
And I'm not speaking about the two yellow spring but one more little
Check out 4:58, I think it may be the hole nearest the center?
@@PerthWAtch Thanks again. I'll go in an assistance center!! :-)
Pity nothing said about significance of AC instruction on installed label. What is AC and when do you need to apply discharge instruction? Otherwise, excellent tutorial!
Never needed to do that and not sure what it's there TBH
Just watched further instruction videos that clarify the significance of the AC terminals. Stands for All Clear terminals that require earthing with the prongs of metal tweezers, either by simultaneous contacting of the AC terminals with the metal case of the watch, or with the positive back of the inserted battery cell. Action clears memories.
So do you have to do that or not? Optional?
@@PerthWAtch There’s a reason that the advice is printed inside the watch case and I’m happy to follow it. My limited understanding is that the AC discharge only needs to be applied if the watch face doesn’t display digits when new cells are inserted. Interestingly, the first time that I attempted to replace the cells on my Protrek, back in the 1990s, the face screen remained unresponsive - ie blank. I didn’t have the benefit of the help now provided by other DIY owners on You-tube. I panicked and sent the watch to Casio. They charged an arm and a leg to replace the cells and, thereafter, was determined to research what I was doing wrong. Turned out that the blank face was because I hadn’t discharged the AC terminals!
Not sure whether that adequately answers your question. Incidentally, although the clever functions are now superseded by smartphones, I still wear the watch and regularly use most of the functions, with the notable exception of the alarm. At my age, I’ve largely lost sensitivity to high frequency sounds. I can only hear the alarm if I place the watch next to my ear which makes the function somewhat pointless: and I don’t need to wear a hearing aid for normal day-to-day survival!
Ah yes I believe I read something akin to that before… however the phenomenon of the screen not displaying after a battery change has never happened to me and no one can explain the circumstances which might cause it to happen. Nonetheless, useful to know.
As for the functions superseded by a smartphone, well I don’t agree completely - as you might have seen this was a Pro Trek and smartphones cannot give you local temperature, barometer and altimeter readings!
You forgot to reset the watch after replacing the batteries as shown on that label inside the watch.
Doesn’t look like you need to do that at all
good afternoon, I have a protrek PRG 80 YT the functions are blocked and an OP EN message appears. I have already reset it but the OP EN message continues to appear
Apparently that’s to do with the case back having been opened but not having all the covers and/contacts out back properly... I would recommend posting your question on a good forum eg. WUS.
My watch wont start. Pinned it but nothing happens
Same model as yours
I am sorry to hear that
@@PerthWAtch is there something i could do?
Not sure - either used an authorised repairer or post on a good forum perhaps?
How to change battery potriek 3415 and battery number
Title for the next video??
@@PerthWAtch battery number
You mean Pro Trek with module 3415? Dude that's a tough solar module... you don't change batteries on that.
You forgot to mention about resetting the watch after battery change by connecting the dots in the AC using a tweezer. Otherwise, the battery wouldn't start up.
Yeah there's some rumor about that... but I didn't have to do that at all. Working perfectly fine after the procedure I showed. Fake news perhaps? ;)
@@PerthWAtch I would agree, except I found your video because I was looking to change the battery on my prg 40 and after following the same steps, the watch wouldn't power up until I shorted the two points in the AC using a paperclip did it started to work again. Still your video guide me most of the way until the last step of shorting the AC.
Cool... well I'm glad you found this helpful :)
You would not believe how many watches I’ve gotten thru lot sales because of people not knowing or not wanting to change out a battery. Oh well, good deal for me.
Cool! Well I guess I should never underestimate the laziness of men :)
Make sure you have the smallest screwdrivers in existence
I didn’t… and I managed ;)
@@PerthWAtch I tried, and didn’t manage
Just so you know not the right procedure for a PRG-80 version watch.
Good to know! I think people attempting a battery replacement should first try to search for model specific info!
