  1. Another Accutron 214 found its way into my shopping cart. Not sure how that keeps happening... I've always liked the railroad dials, and I'm a sucker for the blued hands. This one was sold as running, for a nice change of pace.
  2. I've been servicing Accutrons for some time now. But yesterday I just had an AHA! moment. When phasing the 214, I had been using the power from my Accutron 700 test meter to supply voltage to the watch. I would clip one lead to the ground strap and used one hand to press the positive lead to the battery terminal. This leaves only one hand to adjust the pawl finger. I was thinking of a way to make a battery clip hold the battery in place to make this procedure easier. Then it hit me.... All I needed to do was to flip the ground strap upside-down and use it as a battery clip!
  3. Hi i would be interested in this accutron spaceview but i have some doubt that it has not been converted. Could someone help me to understand if the glass, case, spheres and minute circle are contemporary with this spaceview? I have attached some photos Thank you in advance
  4. Continuing my trip down the Accutron rabbit hole, this non-running Spaceview is on its way to me. The seller made me an offer I couldn't refuse. I haven't been able to cross reference the serial #, but it looks original enough for me.
  5. …you all find some lovely 404s. Here in the US it is a challenge to find this kind of potential. Perhaps our elders sported too many Timex and Accutron and other things with plastic movements. Bradley Mickeys with pin levers and maybe 1 jewel…but well above the 404 I’m afraid…
  6. The classic problem of the center wheel assembly has rusted itself to the post. Then a minute and hour hand no longer turn the secondhand churns the friction part of the center wheel assembly is totally destroyed. Occasionally can flip the wheel over and buy yourself a little time but typically you'll have to replace the wheel. Then if you have really enthusiastic user you'll end up with a minute wheel stripped also. I would recommend not following the lubrication specification of whatever they say for the center wheel to avoid this ever happening again. I really wouldn't worry about the magnetized components unless you get rid of the magnets on the tuning fork. Basically magnets on the fork everything else is going to have a problem with magnetism typically is not going to bother anything at all unless of course you have steel tweezers. Oh and when you finally get the screws off and remove the fork be very careful because typically underneath our spacing washers. The color-coded to refer to their thickness. But I find it's usually best to just put the screws back in once you've lifted the fork out of the way that way you don't have to worry about which washer is where and basically is random whatever you going to find. The purpose is to tilt the fork so it agrees with the circuit. In watch repair yes you're supposed to pay attention but this is example of where you really have to pay attention otherwise well at least the fingers can be replaced. So they have to be at least one of them rotated out of the way to get the fork out. Then typically I rotated back and after the wheels are out I put the bridge back on to protect the finger when it's in the cleaning machine. Then when you're putting it all back together of course you remember to rotated out of the way and put it back etc. oh and remember to rotate it back before you put the screws in for the tuning fork because typically it sticks up too high and he can't get it past the screw head. So basically there's a lot of rotating that finger around to do things and it has to be in the right place or else, did I mention they can be replaced? Phasing on silver cells is interesting. Then yes you really should have a variable voltage power supply but there is something amusing about all of this. For instance is a technical specification for their watches and notice I marked something? As we know running on a silver cell has too much voltage out of the package brand-new without a load you can get almost 1.6 V and they are originally designed for Mercury batteries so obviously that is way out of specifications but if that is true why on the technical sheet is there the high-voltage run check? Which by the way is not mentioned in the service manual because normal service manual relies on using the normal meter and your source of power would've been the Mercury battery which cannot get to the voltages listed here One of the amusements and watch repair is service manual versus the factory? Or sometimes service manual versus other technical documentation that you typically don't have. In one of the other discussion groups is somebody who worked at the factory and she had pointed out that they use a variable voltage power supply and they did test the watch at a higher voltage. Then I'm attaching a PDF an interesting article about the problems of silver cells. 1996-08-web horological times Accutron silver cells phasing.pdf
  7. That is a very good question. It's not that easy to bend the post with tweezers, etc., as it has a lot of movement at the bottom where the hack spring is. Who knows? Good luck with your Accutron(s). Cheers.
  8. I was asked to look at an Accutron 214 that could hum but doesn't move. I removed the safety bridge and immediately noticed that the index jewel was missing. I searched the movement and also the watch case but couldn't find the missing jewel. Has anyone tried replacing a missing index jewel before? What bonding agent would be good for bonding to a ruby surface. Or is replacing the entire tuning fork the best way to go. TIA
  9. Unfortunately, I found the tool I bought didn't actually work for the 218 series, so the particular tool might be for the 214 only. I wished in one hand...again. JohnR275 is correct about that tool for the phasing of 224 series Accuquartz movements. It looks like a movement holder with a couple of thin probes built in. If you have one of the Bulova series 300(?) movement holder with the removable probes and nylon sizing pegs, it may work even better. Good luck with your Accutron. Sorry about the late response. Cheers.
  10. Hi I have a Bulova accutron with swiss eta 252.262 movement. The watch is having an issue with the date change function, when I rotate the crown for date change it instead moves the hour hand and not the date wheel. I can continue moving the hour hand twice around and date does changes . The date is changing every 24 hrs . Any advise how to fix this issue ?
  11. Howdy, y'all, from sunny South Carolina! I'm just starting my horological adventure, inspired by a 50-year-old Accutron (218D) purchased for my 50th birthday last April. There was a sentimental consideration when selecting a family present for a my semi-centennial celebration: What's more appropriate than a historically significant timepiece that has been ticking as long as my own ticker? (OK, before my fellow Accutron brothers and sisters speak up, it hums not ticks.) Before that, my interest in watches was strictly practical and job-specific. As an outdoorsman and Scout leader, my "collection" consisted of G-Shocks, Suuntos and Garmins, with a smattering of analogs from Fossil (yes, I know). Since that fateful birthday, my interest in "real" timepieces has exploded. Who knew one could spend hours window-shopping online for watches on eBay, or watching repair videos on YouTube?! I purchased a second, non-functioning Accutron (N3-218D) with the goal of learning how to repair it. Then came from Amazon shipments of tweezers, loupes, movement holders and all of the accoutrements necessary for the task, as well as the skeptical looks from my lovely wife... I found a source for the appropriate coil that seems to be the most common culprit and stripped the movement down to individual parts. And then ... Without a 20+ power microscope, I'm stuck; thus, the wait continues as I source an affordable microscope that won't draw more severe looks from the love of my life. I've started a small, thought-out and affordable collection of watches, including a new Seiko 5 sport (4R36) and a Tissot Chemin Des Tourelles (Powermatic 80) dress watch. And just this week, I received two vintage (can't believe I'm saying vintage) 80s- to 90s-era Seiko 5s from eBay: a functioning 7009-876A and a non-functioning 7S26C (from which the balance cock screw is currently hiding in the berber carpet of my home office). Along the way, I dragged my teenaged son into this new world. One of his 15th birthday presents was a simple Orient Bambino, and on his own volition and using his neighborhood lawn-mowing earnings, he purchased a beautiful Seiko Presage dress watch for church. I suspect I will be tapping into the vast experience of this forum often as I semi-ignorantly dive head first into this new adventure, and in advance, I thank you for your patience and guidance! -Mattutron (North Augusta, SC)
  12. Looking through my Dad's tools, I have multiple Accutron back wrenches. I also found three index wheels. Cannot tell which model they are for, however. I put an accutron on my Vibrograf B200A and I get squirrelly results. Frankly, I never understood how the vibrograf was supposed to be able to read an accutron--knowing the principle of the vibrograf operation. I never gave it much thought until today. But, the accutron is keeping good time...maybe 3-4 seconds a day. --------------------------*** AHAAA!! Push two buttons...the Accutron button plus one other. And just like that, my Vibrograf is useful again!!
  13. From a recent junk watch lot from eBay, I found a ladies Accutron watch. I was expecting a ETA quartz movement inside but to my surprise and delight, it's an actual tuning fork watch. But my delight quick turned to disappointment when I discovered that someone jammed in a wrong size battery in. The battery is so huge that it has deformed the forks to the maximum limit. I tried prying it out but it's really stuck fast. Does anyone have the service manual for a ladies Bulova 2210 movement? I have to figure out a way to get the battery out without causing further damage. Thanks in advance.
  14. I've been working on a couple of Accutron watches all this week. Both of them are non-runners from a watch lot I bought last year. Both of them qualify for the 404 club. The first is a 218. The caseback wS missing and a whole lot of stuff got in. The coils tested ok but I suspect the transistor is the culprit. I am planning on replacing it with a 2N2222, SOT23 transistor. The second one is an Accuquartz 224. There is a hum when I tested it but the hands won't move. I've cleaned up both movements but I just figure out how to get the capped jewels out. They look like novodiac type jewels but are so tight that the ring doesn't turn. I need the help of you Accutron experts out there. Is there a special tool needed for these?
  15. I just acquired this tester and want to use it as a general tool working on quartz watches. 1) Does anyone have the schematic of the tester because I may want to mod it? 2) Can anyone tell me what is in that accessory puck that I am pointing to? @JohnR725must surely have the answer to both of these questions!!
  16. Hello everyone, I hope this finds you all well! So a friend of mine picked up a non running Accutron 214 and asked me to have a look at it for him. I’ve worked on a few in the past but this one is giving me some trouble. The watch hums nicely but when I look at the indexing mechanisms something seems a little off. I’ve been going through Henry Frystak’s tutorials about indexing and also have compared it to some of my personal Accutrons and something doesn’t look right. The jewels are extremely close to each other compared to watches I have and videos I’ve watched. Also, the springs, if possible seem long? In Frystak’s videos he mentions that both springs should have a slight bend in them when not in contact with the index wheel, but be flat when in contact with it. If these springs would be flat they would be really high on the wheel. From what you see in the picture, is this something that can still be adjusted or is something else going on here? Any and all help would be greatly appreciated!
  17. I think most of us use a 0.5 barlow lens, giving a magnification of 3.5 - 22.5 X. The 0.5 barlow lens halves the magnification but doubles the working distance. When I want higher magnification, I use a 20X eyepiece. This gives a magnification of 14 - 90 X, but at a more useful working distance. The only time I wished I had higher magnification is when working on Accutron watches. The teeth on an Accutron index wheel are so small, that even at 90X magnification, they are still hardly visible. But higher magnifications with optical microscopes become impractical because of the shorter working distance and shallow depth of field. I'm still trying to convince myself to get an industrial digital microscope with a magnification of 200X.
  18. I love your updates Ross, you're making good progress. Do you have any immediate plans to learn some repair techniques involving staking and jewelling tools ? Many years ago now but It was my first time for having bacon eggs and honey pancakes on the same plate, i remember thinking # what the hell is this all about # You can do it Nessie, organise that space , set up the scope, lay out the tools, crack your knuckles stretch out them pinkies and off you go. Is this the single eyepiece accutron scope ?
  19. Hello everyone! So I've picked up a Accutron 214 non runner and decided to have a go at servicing it to see if I can bring it back to life. I own a few accutrons but have never gone this far into one before. So after cleaning and inspection I have found the 4th wheel has some damage. Doing a little research, it looks as though the 214 and 218 4th wheels have the same part number. Before ordering one for a 218, I was just wondering if anyone can confirm that they are the same?
  20. I recently picked up a late 1970's Bulova Accutron Deep Sea 19810 "devil diver" with the Caliber 242 movement. It is a very impressive movement in terms of its modular design and I would love to see it running again. I have taken apart the movement, cleaned the mechanicals and put it back together with everything running smoothly when manually manipulated. I installed a fresh battery and the stepper motor will click twice in one direction, not enough to move the seconds hand, and then reverse direction for a couple of clicks. This goes back and forth a bit then stops. Just to be sure I removed the hacking lever and checked the mechanicals and cannot find any fault. So I am guessing this is a problem with the stepper motor. I would appreciate hearing if: a. Does anyone have any further ideas about what might be wrong/ what I might try b. Does anyone have a 242 movement or stepper motor that they would sell me for this project? I have searched the web for a motor and cannot find one in stock, but that is not much of a surprise. Thanks in advance.
  21. @JohnR725Forget I ever mentioned anything about age. Is there really such a thing today as "Synta Visco Lube"? I was wondering what the Moebius equivalent would be for the two oils (OK, one grease, one oil) that the manual suggests. I have Moebius 9000 for quartz watches. Would that be a good substitute? I've been using 9010. BTW, have you seen the Horotec oiler I mentioned? I don't recall having seen them sold until very recently. It's possible that they've been around for years but I just missed them. The wire that they use is very thin indeed. Maybe even .06mm, if that's possible? I received the Accutron index/pawl post tool yesterday and I'll see how that works for getting the pawl finger sitting better. Maybe I'll get lucky and I didn't de-mag the fork by pulling it from the US while it was running. I hope I wouldn't have to be lottery-winning lucky for it to be possible. Cheers. @JohnR725Oh, and BTW, since you attended Accutron class, and are obviously quite knowledgeable about them, I'm wondering if you know an Accutron expert named "Samantha"? She used to post Accutron related posts on the NAWCC board but I haven't seen her for a couple of years now. She seemed to really know her way around them. I'm just curious to what happened to her? Cheers.
  22. Hello, I am working on an Accutron Astronaut and after putting it back together, (cased up) I notice it hums, (doesn’t hack) and the minute and hour hands don’t move... everything was looking good during the overhaul. Paul and index line up how they should, the tuning fork vibrates the coils are good. Can anyone with more experience on these help me out? Please and thanks.
  23. Hmmm.... I wonder if they can machine Accutron index wheels?
  24. I came across a replacement motor from Cas-Ker recently but it's a little pricey to just buy and try. https://www.jewelerssupplies.com/accutron-242-step-motor-20-510-900.005.11.html I wrote about my adventures with a Bulova 242 last year. I just bought an untested 242 movement off eBay and am praying hard that it works. You might find it useful. Apparently, this twitching problem is quite common with the 242 stepper motor. I haven't really looked into the cause.
