Casio ProTrek PRT-40 Clean up and Fixing Broken Lug

Recently found Casio Protrek PRT-40 triple sensor watch on Ebay for £15. Bargain! I though. So I bought it. I was told it has a broken lug and previous owner tried to fix it. Unsuccessfully I must say.
Upon further inspection I came to the conclusion that the protrek watch was worn with nato strap which I now know can do a lot of damage to this type of watch.
Without much planning I came with a barbaric idea on how to fix my new PRT-40. If it's stupid but it works - it ain't stupid. OK?
Enjoy!

Great video! Really neat idea with the broken lug solution. I got some Casio's with broken lugs and will try it myself. Also... The angle, editing and the choice of synthwave(FTW!) for music made it a pleasure to watch!

[@Techsas]

Thanks!

[@majorlaw1985]

Very cool work with the soldering iron. That came out way better than I expected. Your videos are always cool as hell. Keep em coming!

[@Techsas]

Aww thank you!

[@harolddaxton3832]

I know Im asking randomly but does any of you know a method to log back into an instagram account? I somehow lost my login password. I appreciate any tips you can offer me

[@ahmedkyree4240]

@Harold Daxton instablaster ;)

[@harolddaxton3832]

@Ahmed Kyree thanks so much for your reply. I found the site through google and Im in the hacking process atm. Looks like it's gonna take a while so I will reply here later when my account password hopefully is recovered.

[@harolddaxton3832]

@Ahmed Kyree it did the trick and I finally got access to my account again. I'm so happy:D Thank you so much, you saved my ass!

[@marcoramirez2703]

This channel deserves more support, the content is awesome

[@Techsas]

Thanks! It makes me very happy to hear that!

[@AlwaysBolttheBird]

I would like to see a “6 month later” vid on the fixed lug. I assum it would be fine you just have to make sure the plastic actually welded together

[@TheEksar]

i prefer fixing plastic with super glue and soda + permanent marker for colorizing. When you heat up the plastic it may change its properties and become quite fragile

[@I967]

Thanks for this tip, I fixed three broken lugs this way. I wonder how long it will hold up. Now my Casio W-S210H isn't junk anymore!

[@tnkwok9682]

very impressive on the cleanup and especially the lug fix. great video!

[@Techsas]

Thanks!

[@HamiltonBarbosahb]

I'm a fan of Casio watches, great video! you are an artist !!! Congratulations !!!

[@Techsas]

Thanks!

[@pineapplej7310]

good job with the plastic welding. i suggest getting a small sading sponge of various grits and going over that to make it look smooth again. it has a very low grit sanding that breaks up the appearance.

[@sportsandsportshighlights6674]

2023,a very cool and educative video. keep it up

[@miguelrosales8326]

Man. I have an old Casio watch with the same problem. Thanks for the idea!

[@Techsas]

You're welcome!

[@Dycdom]

Dude ... that’s music is sick reminds me a bit of Com Truise ! And cool edit. And the video made me thinking to restore my trusty CASIO PRG-80YT. SUBSCRIBED

[@Techsas]

Glad you enjoyed!

[@gnokketto7423]

nice fix, how to buy the same strap ?

[@CrisTheFist]

Are you able to remove the bezel to clean underneath? I bought an old one and it appears there is a lot of debris between because the bezel is stuck and won't rotate.

[@grzesiucustoms195]

Hello, what kind of material you've melted for the case repair? Is it any specific type of plastic?

[@TDII2]

I think it's not permanent repair and easy to break again....but it's good tutorial for temporary....any update?

[@VeritasKonig]

Great repair video! Is that bezel replaceable?

[@cis4coffee]

That was very interesting...I was wondering how you were going to make the lug hole and that tiny little hand drill was very impressive. Excellent clean up job and a great way to keep a good product getting some wrist time.

[@Techsas]

Thanks!

[@lostpianist]

Did the depth sensor work after the clean up? I have a similar dirty sensor... on an ARW-320 Alti Depth

[@vinnividetti]

Hello, what type of glass does this protrek have? mineral or acrylic? I need a little information since it has been grated, a little. Thanks a lot.

[@adalidvega2007]

WHAT A JOB!!! CONGRATS.

[@yerkodiegoborjakvessitchva2183]

VERY NICE . WELL DONE ! . 😉👍

[@IIIJFRIII]

Is there any way to replace the big button on the bottom?

[@Techsas]

You'll probably need another big button to do that. 3D printer is another way.

[@IIIJFRIII]

@@Techsas o good to hear. Hunt one down on Ebay maybe under extra parts.

[@Techsas]

@@IIIJFRIII They are quite expensive tho

[@aaahbeeeh3374]

look for spare parts of the prt-40. if not, simply recolor the lettering with a marker in ur desired color.

[@maciejd7823]

Just ordered Huawei smartwach with broken lug for cheap. I want to try this method, how does it hold up?

[@Techsas]

Not sure, I sold the watch but didn’t hear any complaints.

[@ehinspections]

Thanks for sharing! I am thinking of taking the whole watch apart, because is not working right. Does the back interior working come out in one piece? Thanks!

[@Techsas]

Hi, yes the module comes in one piece

[@ehinspections]

@@Techsas Thanks, I will try to see if I can get it going, it comes on and it goes off...Thanks.

[@aaahbeeeh3374]

i liked, good inspiration with that plastic melting and attaching. wondering how usual plastic bonds to resin stuff over time. why did u use polywatch for rubbing the bezel and outer parts? its for acrylic surfaces only to remove slight scratches, all else is waste of cash. very expensive stuff as u know. i had also removed the bezel, if still good enough. opened up the watch to clean the mineral from inside. then i had recolored the light pusher-letters with yellow marker. but ey, if its fine for u, its fine. restoring is so satisfying.

[@Techsas]

Hey thanks for your comment. Polywatch works just as well on regular plastic. I just haven't had enough patience to make it as smooth as it can be. Restoring is satisfying, I'd like to have more time to do this...

[@benedictstefan]

At one point the display of the watch was saying "ERR". What was that about? Did you touch the sensor while cleaning it? This is what happened to me and the sensor had to be replaced as it couldn`t be repaired..

[@Techsas]

Hi. Im not sure why does it say that sometime, I bought it like this. Compass seems to work fine.

[@Planeta-Shelezyaka]

@@Techsas this is not about the compass this is about alti\baro. Have the same error and stiil cand find unswer how to fix it.

[@alucardhans]

@@Planeta-Shelezyaka i have a couple of these and the error is when the sensor is disconnected (or loose) or damaged

[@ПлюшидзеиОвал]

​@@alucardhans I know. I also have several of them. I just want to know if someone was able to fix this . Or the reason why this happened. I had a watch with a broken screen and when i try to change it, I need disconnect the sensor. After connecting it back, the altimeter stopped working.

[@benedictstefan]

@@ПлюшидзеиОвал The sensor is extremely sensitive. Even mishandling it could damage it. There are ways to repair that sensor but I don't know who can do it these days. The best chance you have is to find a donor watch and use it's sensor to replace your damaged one. I also recomend the VINTAGE DIGITAL WATCHES group on Facebook. You have a lot of specialists there

[@Vodkarock1]

What type of plastic u use to amend the lug?

[@sofanova6542]

Dang bruh... so thats how you fix broken lug. I gotta do this to my broken lug F91 🤣😎

[@Techsas]

Man just don't buy milky bars for a week and you have yourself a new f91

[@dhirajshetty483]

amazing work !!

[@mariusvranceanvirixDerTod]

nicely done

[@satkum2101]

how has the fixed lug held up if i may ask

[@Techsas]

Very well. I actually broke the watch and the lug was still holding haaha

[@hsvr]

Isn’t running alcohol bad for plastics?

[@Techsas]

Alcohol is not bad for plastics. Acetone is bad.

[@lugin01]

what plastic material did you use to "solder"?

[@Techsas]

Not sure, just whatever I had laying around.

[@mariogjirlic2306]

Bravo,respect...tough nerves

[@YouQube05117]

Sweet! I had the same one.

[@volkanarda5893]

Altimeter and barometer say error. How can ı fix

[@TheHungaryPSB]

Good job

[@АндрейШумилов-ъ3ю]

Well done great! 👍

[@Techsas]

Thanks

[@zainalishafi9222]

where we can buy its accessories?

[@Techsas]

Have no idea...

[@Tchetchen.France]

please tell me how to remove ERROR?

[@Techsas]

I don't know how. One of the sensors must not work

[@jorgel.otarolam.3241]

Broken coil ( altimeter) , it must be welded.

[@R0xanneW0lf]

Yeah, can the Apple Watch do what a Casio can? I don’t think so, CASIO FOR LIFE!!!

[@shmvon]

8 years battery life :D

[@morganelizalde7291]

Yo tengo este reloj alguien me puede ayudar en decirme dónde encuentro el correo extensible original ???

[@didodido5608]

👌 Good work man 👍

[@tarabario]

good job!

[@staszekke500]

Good for you

[@posceve]

You need a Dremel my friend!!!

[@Techsas]

Haha I need many things

[@Amin_2k]

Looks good, but the lug will end up breaking eventually as its a weak point.

[@joseeduarmendoza1113]

Hermoso reloj lindo trabajo, excelent (big job) beautiful watch

[@Techsas]

Thank you

[@IIIJFRIII]

So cool.

change the battery and do an ac-reset. if nothing happens, its most likely broken.
