Restoration of Vintage 1975 Timex Watch with M24/M25 Movement

[@dskim24]

You'd be surprised by how many people say they service Timex, but don't actually do so like this. Yes, getting that one big top plate back on is absolutely the bottleneck of the process. Impressive work, sir, you're really doing it!

[@ForestWoodworks]

I didn't realize you're "not" supposed to be able to fully disassemble these movements, so that's what I started out doing. It's a bit finicky, but after a couple done there's some tricks. It's pretty rewarding when you get one back together and it starts up. 🎉

[@alexr1927]

I literally just disassembled it and can't for the life of me put it back together. Thank you for the video. Wish me luck haha

[@MiguelBricaBrac]

Great work on this Timex. I would love to see films from back in the day on how these movements were assembled at the factory.

[@johnhannon]

I was able to get my 1964 Timex Zorro watch running thanks to your video. It has the M24 movement and was missing the stem/crown. No jeweler or watchmaker would help. I was not asking them to repair it, just replace the stem. I found a source for the stem/crown and I did not take it completely apart like you did. I wound it up and slightly loosened the top balance screw and it started running! The watch means a lot to me because I received it as a gift from my parents in 1964 when I was 8 years old (I am 66). I may follow the Timex procedure and clean/lubricate it some time.

[@jsgwatches]

Glad to hear this John, and glad your watch is back up and running. It’ll have many more years of wear out of it yet! JSG

[@sh1nyarm0r]

In 1975, parts came from Timex Besançon France, movement and bezel assembled in Taoyuan, Taiwan. In the emergence of the One-China policy 1979, I helped Timex build the production line for mechanical and electro-mechanical watches including M100 and M24/25 in Mactan Island, Philippines which became a major assembly plant of Timex that it is today. Every movement passes through and automatic vibrograph adjustment machine for proper timing of the balance wheel to specifications. Amazing watch still works. Takes me back to memories.

[@wsbill14224]

Department stores used to service watches. Cheap watch service like Timex consisted of soaking the movement in solvent then drying and reoiling. They did not take cheap movements apart because they're too hard to re-assemble quickly by hand. Watch cleaning only cost $4 while you shop so they had to do it fast.

[@tribes2archivist]

The lighter fluid used to clean it left residue that functioned as oil, in case you were curious about what reoiling entailed.

[@dwayneharris3874]

Wow! I never saw a watchmaker at work before. You make it look easy. Way back in the late 1950s, when watches were worth fixing, we knew the local watchmaker well. As kids, we were always breaking the strap or crystal, and she would fix it. My current watch is a 30 year old Timex digital, very accurate and reliable.

[@jsgwatches]

Love these little memories of peoples stories with watches ❤️. I feel like the art of watchmaking is making a comeback!

[@Super-ew1ty]

@@jsgwatches Well I have another story for you then. Back when I was a kid, maybe 1975 or so my grandfather died and I found his old watch in a drawer. It didn't work but just so happens the guy on the corner was a watch maker who I cut grass for. I took it to him and he said it was a 1941 Bulova and he'll take a look at it. Few days later he had it fixed with a new crystal even. I'll assume being 1941 my grandfather wore it while serving on the army. He was involved in the liberation of the Philippines. Yes the Army fought with the Marines. I wore the watch until I was grow and even wore it in the 1991 Gulf war which I served. I still have the watch, it's looking a bit rough and not running but I plan on having it restored for my grandson. That watch maker did a great thing for me. A gift I'm still thankful for 45 years later.

[@AstronomyGarage]

I have a watch with an almost identical movement. Thank you for not skipping any steps. By the way, Timex made a truly disposable version of this movement called the M104. This M24 is actually an improvement (the click spring doesn't self destruct over time).

[@wings4victory]

I love watching experienced watchmakers do a Timex movement for the first time. They're commonly perceived as rubbish movements, but after working on them can't help but feel respect for their ingenious design. Inexpensive and serviceable without disassembly. If you fancy putting it back on the timegrapher there is actually a regulator on the balance wheel. I don't think the beat error can be adjusted though.

[@jsgwatches]

I definitely enjoyed the simplicity of this movement, a little fidly to piece back together, but a nice watch to look at! No frills, no nonsense, straight to the point and robust. I’d like to see how the jewelled version fares in comparison

[@wings4victory]

@@jsgwatches Yes! I would pay money to see that! They even decorated their jeweled movement (a bit) I suspect because they were so proud of it. Even the impulse pin is a jewel. Try to find the automatic version if you can- the rotor is decorated. It needs a special tool to get the jewels back in and I've been unable to fabricate one from a screwdriver because it is so small. Good luck!

[@sh1nyarm0r]

It is adjusted once during first assembly of movement through a machine that removes material automatically underneath the balance wheel.

[@hisstorymn]

The plate on in one go?? You sir, either have the steadiest hands in the universe or are the luckiest man in the world! Thank you for making this available!

[@walther9161]

I’ll watch this vid a few more times to service my 1973. I remember my dad dropping his timex, band and all in ronson lighter fluid and hanging it on a mail for a day or two. Ran for 20 years!! Like they say, takes a …. Y’all know the rest . Awesome video

[@stevieminassian3970]

Just soaked my timex auto wind watch hands face and all in lighter fluid for 5 min. And let it dry seems to be working fine now 👍

[@jeromedenmark7587]

👍great job Glad to see a watchmaker who doesn’t look down on the working man’s watch

[@leifvejby8023]

I can't get over how ingeniously efficent an ugly this movement is constructed! Good job getting it running

[@jsgwatches]

The more I looked at it and worked on it, the more I liked it 😅

[@mattobrien3346]

My hat goes off to you sir! You are one lucky chap getting the train of wheels in first time. This is one of the cheapest (if not the cheapest) movement I have tackled myself and is infinitely more difficult that a standard Seiko or ETA. So difficult I got too frustrated trying to line up the bridge and it is still in bits.

[@PrimordialTitan]

He makes it look easy

[@ignacioanaya3403]

First time I see someone servicing a Timex, very good job

[@amandawatson5931]

Simple means reliable. Nice job.

[@ericahrendt489]

Thank you for the video and for showing some love to vintage Timex. I have a 1988 auto winding date Timex apart right now. That dial is epic. When I was a kid one of their tv commercials had a watch strapped to an outboard boat motor under the water level and then they went for a ride. Well as a 10 year old I left my Timex in my jeans pocket and it got washed. No water inside but the hands fell off. I effectively told my mom "That's B.S!". So she shipped the watch to Timex and they replaced it albeit with a different model. Thanks again.

[@brettkaufman2299]

Thank you for taking on this challenge -- I have a few Timex watches to learn on too, and this showed me the way. You are very good at explaining the process of what you are doing and have the right attitude to trudge forward. Enjoyed.

[@jsgwatches]

The watchmaking journey can be equally rewarding and torturous, just need to keep pushing forward 👌 JSG

[@BWV1002]

Thanks for the video. I enjoyed watching it. Great job! I restore those a lot so I would add some info I've gotten from my experience: The dial indicates it is a 1975 Marlin. The case is, however, probably from one of the 60s Marlins. You can see this by matching the case back (waterproof marked) with the dial (water-resistant printed). But anyway, it looks great now :) You CAN find the regulator near the balance. You can actually adjust timing. Very rough but it works. Something called oil cups (balance end-shakes, one on the bottom and one with the balance screw) has to be lubricated. That's a crucial part of oiling this movement (probably you did. I am just mentioning it because I didn't see it from the video). Btw, Timex movements, especially M22/M24/25, last ridiculously long. Many of them are still working without service. Once serviced, they will work for another decade. I don't think Timex had expected that LOL

[@jsgwatches]

Love the additional info you’ve given for this 🙏 always good to learn from others experiences! Putting some oil in the balance wheel oil cup definitely helped this watch fire back up, as well as oiling the exit pallet fork. I did attempt to regulate the watch by adjusting the regulator arm which improved the rate, but the beat error was a challenge to adjust. I removed the balance wheel from the balance cock to rotate enough to centre the “impulse jewel” between the banking pins, but was unable to get anything decent. I’m sure it’s not impossible to get these things running nicely, but definitely a fine art! None the less, I really like the look of these movements 👌🏻

[@BWV1002]

@@jsgwatches I don't know if it's actually possible to adjust the beat error with timegrapher. I haven't tried. I am doubting because what timegrapher says with a timex movement is not precise. Especially the lift angle of Timex movements is unknown as other Timex repairers report. I heard that's why timegrapher can't read them correctly. Mine says sometimes even wrong daily deviation. But maybe it's possible. I can imagine it's a pain to do haha.

[@justinfincher2385]

Thank you! I am wanting to get one of my grandfathers watches working again for a Christmas present for my mother, and I was totally perplexed by this when I opened the back and saw only one screw! I’m so glad you made this video!

[@jsgwatches]

One of the simplest movement designs, yet one of the most challenging to reassemble! JSG

[@danspencer9499]

I actually like that dial quite a bit! Very nice work.

[@igorcabrera8123]

First time I see somebody successfully messing with a Timex. Chapeau!

[@fraserp2377]

Enjoyed this thanks! Would have been interesting to see it on the timegrapher after a dip in lighter fluid 😆

[@unclekevin5094]

I dip mine in Vodka (the cheapest I can find) and then dry it with a hairdryer. A few dabs of WD40 and its good to go for another few years.

[@WyvernDotRed]

27:50 In another video I watched a bit of Timex advertising was shown where they boasted of down to .001 second accuracy. Which converts to +-130 seconds a day if you convert it, considering number rounding. So it's running within factory specification!

[@nickredwine17]

Bro I’m following along on my own movement and I can’t believe you forgot that spring… that just set me back a couple hours 😂

[@jumperpence]

Another great strip down and assembly. I've ordered a couple of GMT watches from India to start me off on my watch making hobby. I'd love you to do a video on one of these. They cost nothing, but have a strong following.

[@jsgwatches]

Good luck with your first watch boss, It gets addictive! And I might look into it, I like working on those types of movements, some of them turn out to be little gems

[@jumperpence]

@@jsgwatches apparently the movement is based on the citizen 0201. 17 jewels, I paid £8 each for working examples.

[@scottcolon4829]

I've got the exact watch. Picked it up because I love the dial. Opened it up to service it and said no way. Good on you for servicing that one. I just put it in lighter fluid. Seems to be working just fine.

[@robtk3]

Thanks for this video. I just bought a handful of old Timex watches on eBay to get started practicing on my new hobby. Having no idea what I was getting into I was thinking I should have looked for some other brand to start with. However, this video has inspired my confidence a bit. I suppose if I can get this this "one bridge design" back together... well, all the better for my future endeavors.

[@jsgwatches]

Absolutely! if you can nail this one, you'll be golden for any other brands. How did you get on? JSG

[@russellmaharlika7556]

Glad to see someone else who took apart a timex. It's very rare to see someone who dares to disassemble a Timex lol

[@jsgwatches]

I won’t lie, I was a little nervous I wouldn’t get it back together 😅 aligning the pivots with the top plate looked like a nightmare!

[@danielrichter2452]

You my friend are literally a god. Well done!

[@stevelandron5892]

Thanks for the video JSG!!! With your help and video I just serviced my 1985 Timex! Your video and guidance are awesome. Thank you!!!

[@lanceorventech6129]

From what I have learned that little golden screw for the balancing wheel it acts like a regulator, If you stiffen it up it stiffens the balancing wheel preventing it from spinning if you loosen it just right you will have a great result on the time grapher

[@flymoracer]

Ideally you should use that screw to set the correct amount of end play on the balance, then regulate with the regulating arm

[@richardperrettwatchmaker]

I think this is a great video! Interesting to see that Timex (in Taiwan?) had poised the balance by removing weight in several areas. Clear photography in good light and helpful explanation ... good work and good photography. Nice one! Richard

[@jsgwatches]

Appreciate the kind words from the godfather of watchmakers 🙏 These little movements are strangely satisfying to work on and have their own charm, I like the clean no fuss, no nonsense design, straight meat and potatoes with no sides

[@pqgscott]

Bravo! I didn't think I was going to enjoy this video but I absolutely loved it! I have a Timex watch similar with the same movement that stopped working and now I may just try to take it apart. Thanks!

[@richardpetty9159]

Best part: “…and when we look at the result… horrendous.” LOL.

[@jsgwatches]

It was pretty bad 😅 JSG

[@scottcolon4829]

I've got the same exact watch. Love 5he dial and Spidel band. Got it running with the lighter fluid method. Probably going to sell or trade.

[@ikeman5774]

I don't believe it. I had one exactly like this when I was much younger. Same dial and numbers. I have tried to find a vintage one on ebay, to no avail. Loving this video, seeing my old watch, or at least one like it.

[@chrisairey877]

I love your vids! This one covers the movement I happened to purchase as my first restoration project, so I was delighted to find it! I'm with you, this thing is flat out weird!

[@hockeyrd99]

I put some Rodico on the side of the balance wheel to hold it in place while I take the v-conic screw out to oil it, then you can adjust the end-shake when you put the screw back in. But honestly, I never take Timex apart like you did. Easy enough to remove the hands and dial, and clean/dry/oil the movement as one piece.

[@MattWillMess]

New to the channel. Have not seem anything else. But you have my subscription after seeing you attempt this tragedy of a repair of a watch. Timex "marlins" and "viscounts" have made me a good bit of money. This particular watch, lightly serviced, cleaned, with a nice band installed, and listed right will bring an average of $150 USD on ebay. There is a popular niche market there. So, though it may be a simple, Toss away watch, if you can smartly do the above things to it and source your processes smartly, you can get a good profit on it. I have about 150 of this styled watch needing restoration. Just haven't found rhe time to do it:/ Much love mate

[@Dimian7]

Omg, the spring on the wrong side REALLY grinded my gears 😂❤️ Champ!

[@jeffrenman4146]

I have the exact movement and it runs but it's a bit tired… I had to take it apart and I put a little bit oil in it just to get it to work yeah it needs a huge cleaning but I can't do what you do… I'm here to say the video was really interesting and so are you. Your incredible. I wish I could do the work you do it looks so fun and rewarding. You're really really lucky. Thank you so much for showing me inside my watch it was fascinating.🤪

Watched the whole process, remarkable! Thanks again for another stellar watch video!

[@tasmaniandevil7610]

Im quite impressed on how professional you took and put together your service has been

[@MichaelB-qx1eh]

I've done a coupe of these now too and must also consider myself lucky that they were uneventful. No problems getting the train of wheels back together, though your tape method didn't work out for me and I knocked it apart. I found I could just very carefully keep a finger on the bottom plate while flipping the movement holder over to put in the screws. What was difficult is inserting the detent springs on day/date calendar models and installing the dials so as not to foul the calendar. Ideally the springs stay in place and don't need to be reinstalled, but ultrasonic cleaning might kick them loose. At this point I've assembled a Timex train of wheels 7-8 times and have a good feel for it.

[@MichaelB-qx1eh]

It's especially nice with these to put a wind into them after full service and watch them start out with very low amplitude but start to pick up a lot of steam as the oils flow through.

[@tracymcknight8978]

You inspired me to take a shot at one of these. Nice work! It's to bad it acted up on you like it dud with the timing. Keep up the good work my friend

[@PraveenKumarVP]

Would you be able to mention what are you lubricating oils you’re using? I’ve just gotten a M25 Timex as my very first project watch and would like to clean and lubricate it as you have done. Also could you link the mainspring tool ?

[@fredericcochin7609]

I have a few of those cheap watches dating back from the 70ies. (Timex and Kelton) I like their design and marketing history and even their ugly movement (I really enjoy the Dynabeat) . Many people hate those watches for not being "fixable". And not being SWISS made. I am astonished by the job you could do on this one, and to see that they can be serviced. Thank you for sharing , I think I'm gonna watch this many times again. Too bad I gave up on trying to service watches but some are pros (you) others are not.(me!).

[@Fatcatbaz]

Great video.. Thanks for not "knocking one out" half way through. That really did make me LOL. It's really interesting how these Timex watches were made and yet work well enough and have lasted. It is similar with the ultra cheap quartz clock movements. Genius in their simplicity.

[@jsgwatches]

😂 I realised my error as soon as I said it. And I agree on the timex movements, really simple and robust!

[@jacksugden8190]

Amazing reassembly

[@TerryMurrayTalks]

Aced that nicely sir.

[@lajoskiss7923]

There is a BCC documentary about the Dundee factory you can watch here on youtube. We believe that they used jigs to put the movements together when you watch the documentary there you can have a glimpse of one of them, so we think. I also would love to talk to the ppl who worked there or to put my hands on one of those jigs. After a little bit of practice and after reading the service manual you can put the main plate back a lot easier than the first time. You are a lucky man if you survive the first service without a nervous breakdown. You did it very well though! I started with M21s I wasnt so lucky / or good and I sacrificed a few HSs on the altar of knowledge. To adjust the beat error I move the impulse pin into position by rotating the HS collet when only the balance wheel is inbetween the two main plates. (this is the risky part hence the destroyed HSs) I dont think that timex ever said that you should put the movement into lighter fluid, they provided a service manual. Lighter fluid actually could work/does work but only if there is no stubborn dirt and those oil cups for the balance wheel many times have rust in them lighter fluid would not remove. You also cannot inspect the parts without a complete disassembly. In the other hand if lighter fluid makes it work who cares? :) You still need to lubricate it and fill the balance oil cups, just like it is written in the service manual which is readily available for download if you look for it. This is a well made video I love. Well done! Subscribed.

[@spalkin]

AND the pallet pin! That's one large group!

[@jeffreyhickman3871]

Just subscribed to your KZbin channel 😀!! I am such a fan of these automatic, and mechanical watches ⌚️ of days gone by. Timex has seemed to lose their "Takes a Licking and Keeps On Ticking". It's said by some that these early Timex's were designed as a throwaway watch, but I somewhat disagree. They may be, but I think that they were designed to be serviced. This is to the financially minded. Your friend, Jeff!!

[@properburger7378]

Wow great watch! Im fascina ted by the Design Challenge that had to be overcome to achieve such a simplified thus interesting running (thanks to you) movement. Ive seen a couple of other videos about this kind of movement, and I think this my favorite. Quite a short one due to the extream luck of you (in the other 2 cases they had to put hours and several attempts to align all together. Hehe in any case, great Content and keep it up!! Gettings from México.

[@adrianbirkett594]

Thanks for that, ya I've seen those before and they ARE a nightmare!. For a better result, the screw on the balance apparently should not be tightened all the way down. It would be a cleaning fluid job for me!. Well done. Adrian

[@ericahrendt489]

The manual states .001" or .05mm end shake on the balance.

[@bostonpaulmakes6927]

That was fun, and I like that you included having to take a Mulligan on the spring. I'll be the turd in the punchbowl and say that I admired the simple brutal nature of that watch's mechanism.

I was hesitant at the beginning as I thought it could be a long day! I found lining up the square hole for the crown wheel and the pivot for the pallet fork helped get the top plate in position, all other pivots then slotted right in

[@thehandler_666]

I got one of these Timex watches from the 70s with the M24 MOVEMENT, it doesn't run properly and honestly though I love it very much I didn't think of getting it serviced. But an interesting movement no doubt.

[@flymoracer]

Just serviced one of these today. Sometimes you are lucky with the plates, but today it was a 90 minute slog to get the plates lined up

[@johnmckinstry8546]

Timex actually had service manuals for these watches so clearly they intended that these watches should be serviced. I have a Timex with an M24 that still goes really well even though it's nearly 60 years old.

[@jsgwatches]

One of the main recommendations was to dip the whole movement in lighter fluid for a clean/service, I'm sure it would have come back with a similar result! JSG

[@ksharp117]

I wouldn't say timexs recommendations was just simply dip the whole movment in LF. The manual said to remove cannon pinion, ratchet wheel, crown, date wheel and balance wheel and clean parts as normal in only standard cleaning solutions. Then reassemble and lube. It also gives a full diagram of the movment saing "If further dismantling is required....." and instructions on how to do so.

[@rubinsteinway]

Yeah, I've heard elsewhere that you just need some lighter fluid to clean a Timex. Is it necessary to obtain the user manual for each Timex watch to verify that? Thanks for a nice vid.

[@davidwall6020]

Maybe some oil on the balance pivots may take the sting out of the beat error? Question is; will oil help or hinder the balance staff V Conic pivot friction? These are little devils to even theorise about but are very very clever designs and manufactures. Very interesting engineering project analysis for metal/ product design students and professionals alike. Good inspirational video youve done... great to watch. Ill watch all your others. Dave

Man you are a gem. I have a timex mercury without date with the sane movement. I fully wound it and it stopped working otherwise was working fine. Should i repair it or can you help what should i do

[@justafanmarvel9669]

I believe that this watch does not have the original case back on it... based on the stamp on the inside of the case I believe the back is from a 1966 timex... so it's likely that this was a 75 watch not built in Britain but built in Taiwan for the American market. In fact I'm definitely sure that the case back and dial are from 2 different watches... the. Case back says waterproof on it which indicates that it is much older then 1975, and the dial says water resistant which would be correct for 1975... possibly the whole case is older then the dial and the movement... it's a timex Franken watch lol... great job on the servicing though.

[@jsgwatches]

Ignore the error guys, I meant to say the Uk factory was in Dundee, not Aberdeen!

The ironic thing is that is says made in Taiwan on the movement. Big business screwing people over since 1975

Good job! i am just a hobbyist and have never managed to get a Timex back together. I always wonder how they did it in the factory.

[@jsgwatches]

I was thinking the same, practice would definitely help, but putting several of these things together by hand in the factory without any jig/machine would be an art!

@@jsgwatches Wouldn't surprise me if a machine did it.

This type of watches are called “tel maşa” in Turkish. Which can be roughly translated as “tin fork”. They are called like this probably because of the pin pallet escapement.

I came here looking for advice on adjusting beat error, half an hr later.. ah. Haha! Regardless really enjoyed the take down, thanks.

Amazing work. Any plans for future timex restorations?

[@jsgwatches]

Absolutely! I really want to find a nice jewels version of the M75 movement. JSG

Wow. Excellent work. Great video. You have lots of patience. How many years have you been repairing watches?

[@jsgwatches]

This watch definitely took some nerve 😅 the top plate is a fiddley plate to reposition. I picked up watchmaking during the lockdown last July, absolutely fallen in love with it!
