I have an Accutron 700 meter. What puck are you referring to?

I renamed the file when I went searching for it all I had was a PDF labeled 221. then it doesn't even start off like one of their normal manuals somebody gives us a bonus page and conveniently skips over the title page. Accutron 221.pdf

Worth just searching for Bulova 221. The zero on the end for 2210 indicates no complications but most references are just to 221. With that you'll find articles like... http://mybulova.com/sites/default/files/file/1974_Power_Cell_Replacement_Guide.pdf https://reference.grail-watch.com/movement/accutron-221 .. which look like they could be handy. Also Google watchguy bulova 221 which should point you to a Technical Letters reference of interest.

I found this on the net. Accutron 2210 uses Maxell 329 SR731SW. I also found many asking for the service manual which many can't find. I haven't found any leads to one, sorry.

This is my latest acquisition. All cleaned up and lubricated. It still runs about a minute fast per day. I'm not sure if it's a phasing problem or the oscillating frequency is off. I'll probably test it with my frequency meter to find out. Is there any timing machine that can be used to regulae an Accutron other than a Vibrograf? I don't think I'd want to repair/ restore a Vibrograf and go through the hassle of using paper tracings.

I think it might help to have a definition of what the word means which is not tuning fork watch but this ACCUTRON stands for “ACCUracy through ElecTRONic". Or basically it's a nifty word that sells watches whether it has a tuning fork or not. then for phasing are using the instructions in the book or the instructions at the website below? the reason I point this out the website below tells how to phase the watch for silver cells. http://members.iinet.net.au/~fotoplot/accphs.htm

Hello - I started getting interested in watches about 10 years ago when I interviewed a local watchmaker for a design project in school. I picked up a 1965 Seiko Weekdater around that time and have sent it away to be rebuilt once since then, wearing it daily, pleasantly ticking away on my wrist. My wife's father passed recently and I was given his daily-worn 1976 Bulova Accutron in non-working condition. I finally got around to trying to sort it out and I was surprised to find that it needed more than a battery and also surprised when researching that the movement is so different and transitional. I would not really dream of tangling directly with the Accutron guts so I sent it off to someone with more direct knowledge and an appropriate parts-bin for it (works great, now). Along the way, though, my own interest was piqued and I looked around for more simple watches that I could perhaps learn on, with the objective of being able to service them and know them. Soon I had several decades-old soviet watches in the mail from Kiev which I'm having fun wearing and restoring but would eventually like to service. Now I have an ST-36 on the way, a very-expensive set of small screwdrivers and tweezers, magnification, and I've sprung on this course bundle after surveying a few options. I have a background of software, and lots of automotive projects large and small, but nothing so fussy and tiny as watch maintenance in my resume. Hoping that pure curiosity and interest can push me forward through any frustrations. Glad to join this community and please wish me luck! steve

NOS stems and donor watches are getting increasingly harder to find. I've been toying with the idea of removing the old crown and cutting threads on the stem to fit an OEM crown. One day I'll get down to doing it. Right now I have an Accutron crown that sticks out by a little more that a millimeter. Obviously it doesn't belong to this case. And it's also a pressed on crown. Hmmm...

Thanks Graziano. I've watched of them before. But if you notice, when it came to the part when he set up the Accutron test meter to do phasing, the video was abruptly cut out ( end of Part 3). The video then continues with the casing up and finishing of the watch.

Thanks Graziano. That was very informative. Have you serviced any tuning fork watches before? Would you kindly share your experience? As for Nucejoe's request for a service walk through, I would be too embarrassed at this moment to post one. I was just stumbling around clueless. Maybe after a few more Accutron repairs, I may dare post one.

Would the coil resistance reading give any clue as to which oe is broken? I read that there are people specializing in recoiling Accutron coils. Have you found anyone able to that?

From mybulova.com 1962 The Accutron Tuning-fork watch becomes the first wristwatch certified for use by railroad personnel. 1962 is also the year that Bulova introduces its Caravelle line of jeweled watches. Designed to retail at $10.95 to $29.95, Caravelle competes with non-jeweled watches in the same price range.

Cannon pinion/centre wheel slip is very common on Accutron 218 series.... A nice bodge to prove it is remove the wheel take it off the cannon, reverse it and refit. You may then get it working again, but make sure you oil/lube it before use, the interface between the cannon and centre-wheel...

I balanced the tuning fork last night. I removed the gear train and just applied power to vibrate the fork. I adjusted the "regulator weights" until I got the oscillator to run with minumum current. I then put back the gear train and proceeded to phase the watch as per the instructions in the Bulova service manual. This time I managed to get the index wheel to run-stop-run. Hopefully the watch is phased correctly now. I did try connecting the spare +ve lead wire from the Accutron test meter to the test point on the IC. But the meter needle went off the scale and I aborted. 20210616_215716.mp4

Hi Hector found these for you, Hope they are of use to you. cheers Accutron 224.pdf Bulova 218 Series.pdf Bulova 218D.pdf

Had this problem a few weeks ago with my own 218. Make sure that nothing is making contact with the case back and the gasket is installed properly. On mine, I’d not got the gasket on properly, the watch would run fine with the back and gasket off, but stop the minute both were back on. Took a bit of fiddling to get them back on in a way the my accutron liked. Seemed to be very little rhyme or reason to it either, but it’s worth noting my accutron doesn’t have the original gasket with it either.

The original Accutron batteries were 1.35v mercury cells which have long been off the market. With a 218 movement you can usually substitute a standard 1.5v battery without issues but I believe the 214 models struggle with this. Interestingly, it looks like some suppliers have come up with a workaround for this. I've done two Accutron repairs and in both cases I just plopped in a new battery without thinking about it beforehand. You can adjust the Index finger and pawl so that they are not contacting the index wheel before dropping in the battery but if you do that you'll have have to move them back to get the watch to keep time and getting them just right is the hardest part of the service. Testing the movement of the gear train is a bit difficult too since the wheels are well hidden under the bridge and manipulating the index wheel (driving wheel) is not a good idea. It's an interesting conundrum for sure; hopefully someone more knowledgeable will pipe in with some good advice. There is a woman names Samantha on the NAWCC forum who is quite knowledgeable about Accutron service procedures. I perused all the related threads there and also downloaded the service manual before getting my hands dirty. In the unlikely event we all draw blanks here, I would suggest posting the question over there to see what they may know.

My name is Jaime and I am a watchmaker certified by WOSTEP. Work out of New Mexico. However it’s my first time doing a astronaut watch, I had fixed a couple 214s 7 years ago. Now I am wondering why I took it in for repair. I was referred to this place by a wise watchmaker. I am working on an accutron 214 astronaut watch. For my misfortune or fortune I can’t seem to get it running. The index and Paul are just how they should be, there isn’t any blockage to the gear trains or motion train until I put the hands on. Also not hacking, there is a good hum, but minute and hour hands won’t move. Only second hand moves but won’t hack.

Hi you might find the attached accutron service manual of some use. cheers accutron_service_manual_series_214.pdf

Hi everyone, My name is Gordon Chow, and I have always been interested in timepieces. I used to replace the movement entirely, but have been interested in learning to repair the movements themselves as ETA movements are no longer available. My first watch was a Bulova, and my favorite watch is a Bulova Accutron 63c105 (their last watch to use ETA 7750 movement) that I received for finishing university and starting my first ‘grown up’ job. I wanted to join this knowledgeable group to learn more about repairing movements and join the class.

Hello, I have been collecting watches for a few years now, and have interests across the spectrum. I am most interested in vintage watches, but do still have a number of modern pieces as well. My collection consists primarily of Seiko and Timex, but I also have some Accutron, Vostok, Rolex, Omega and Zenith as well (amongst a few others). I have done some of the basic cosmetic watchmaking tasks of crystal replacement, gasket replacement, and case cleaning/polishing previously with success. I am an engineer by occupation, so my desire to learn watchmaking is primarily at the hobbiest level right now. I would eventually like to be able to pick up 'rough' vintage pieces and perform restoration work on them, but also learn to maintain my collection to a certain degree. I have purchased a pretty wide range of tools at this point, mostly cheap ones, but a few of the nicer Swiss made products as well. My intention is to start on some of the Timex and Seiko pieces that I have picked up as parts of larger lots. Most of these pieces are of little value, and have pretty simple moments, so there is minimal penalty to the mistakes inherent with the learning process. I look forward to the wealth of information on the forum and am excited for the benefits it can provide in my horological journey. Thanks in advance for the assistance and acceptance from its members!

Ok in my effort to try and determine the case construction of this N6 Bulova Accutron, I came across something interesting. I was looking at a couple of Seiko 5 Sportsmatics that I have and noticed something. In the pictures, from left to right is a Seiko labeled "EGP" (left), Seiko labeled "SGP" (middle), unmarked Accutron (right). Now I can tell a difference between the "EGP" and "SGP" Seiko cases. I don't know if you can see from the pics or not. In the "SGP" near where the lugs meet the case, there are small blackened areas that seem to me to be "base metal" beneath a gold plate. This is not the same as the "EGP" which does not have these spots. Now, I assume for Seiko, "EGP" stands for electro-gold plate while "SGP" stands for Seiko gold plate or solid-gold plate. The Accutron has these same blackened areas at the lug ends as the "SGP". These areas almost look as if there is a base metal covered by a gold plating. As I said the "EGP" does not have them. Can anyone confirm? Sent from my iPhone using Tapatalk

Wonderful to see this. My dad was really proud of the accutron work. He started doing them near the end of his career. I wish I had paid more attention at the time, but I was busy building my own career.

I would say current consumption is somewhat important if you don't want to be changing the battery every few months. The gear train of a quartz watch is so delicate that testing it by turning the wheels is not a good idea. And with a stepper motor at the other end, you can't get the wheels to spin freely. Without a current test, you'll never know if there is a problem with the circuitry or resistance in the gear train. That's the reason why some watches stop working soon after battery replacement. I test the current consumption of my quartz movements with the Bulova Accutron meter. It might not be as accurate as a Witschi but it'll do the job.

welcome - welcome. the Bolova Accutron history is Very interesting, but not well understood buy the collectors or the "watch mechanics" (electronics). i have a spaceview (as found) and several emty nice accutron cases. i am shure you will have a lot to offer this good forum. vin
