Try it out for yourself. Do you find 22.5x sufficient to oil a pallet jewel? Is 3.5x wide enough to see the whole watch? Like I said, the only time I need higher magnification is when working on Accutron watches. Possible upgrades that you might want to consider are a led ringlight for shadowless lighting and a tiltable microscope mount, so that you won't need a step ladder.

I have an Accutron Railroad (218) somewhere that has two hour hands, like a Gmt. No way to adjust the difference aside from resetting them on their pipes. Always found that weird. Now here's one with two crowns and no GMT. Weird.

If you look carefully it's not your normal screw back as you're already noticed. Typically you see similar things on Accutron Bulova watches where there's an outer ring that screws on. But this ring doesn't look like it's screws it looks like its locked into tabs four of them on the case. The problem with outer rings are ideally you should have a special wrench. Another was it fits into the notches and then you can turn. In the case of Bulova they do have a special wrench. You can use your standard case wrench except. Normally with a standard case wrench to tighten it up and hold the back tightly when you rotate it you do not want to grab the back itself tightly as typically it's held in place with a tab or something in its physical location. So all you want to do is rotate the ring Only.

I thought that was the spare crown in case the primary crown fails you can use the spare crown? Interesting that it doesn't have the other hand or even a bezel to rotate? Then I'm attaching a supplement that covers the thing is that the other crown can do. Bulova-Accutron-2185-Manual.pdf

Well I finally did it. Dug out the old Hamilton with its demised 500 movement and modified it--just a bit! but not with a 667 Hamilton to make 'Pacermatic' oh no, much more fun with a tuning-fork movement, still 'electric' and still a revolutionary movement, with that graceful seconds hand flow motion. Go Quartz?--You Must be joking! The original 500 movement had broken trip/contact wires, and try as I did, cant find any anywhere. Looks like they went unobtainium sometime last century! I recently got hold of a mens Accutron, I had thought was a 2180, but turned out to be the smaller 2301 so-called, ladies movement in the mens case with a substantial brass spacer-ring. This movement is just a fraction bigger than a British penny, runs at 480Hz with 240 tooth Index-wheel but unlike the other ladies Accutron this caliber has a seconds hand. I dismantled both watches. The coil was dead in the Accutron, so I sourced another complete working watch for £20--Bargain! I serviced the first movement then borrowed the coil from the worker fitted it, where it ran under a glass in its holder for a couple of weeks. I used the now coil-less worker movement as a template for my experiments. I examined the Hamilton movement ring. This part has two projections that serve to retain the battery overhanging the side of the 500 movement, so these would need to be removed. A small grinder took care of that. I now had a more or less round hole in the Hamilton spacer-ring, into which I hoped to fit the Accutron brass spacer. The Accutron spacer was just a little too big, so I reduced its external diameter a little until it fitted the Hamilton ring. I lined up the stem slots and roughly held in position with rodico. fitted the template movement in the middle then came the dial. Here I had a problem. The feet were exactly in line with the outer diameter of the Accutron movement and the inner diameter of Accutron spacer-ring--Bugger, they had to go, which is a shame as I had wanted to retain them, hoped to drill the spacer-ring to accept them, it was not to be! So,--Off they came and the dial feet stumps ground down flush. Again with Rodico (love that stuff!) held the dial to the combo spacer-ring then offered it all into the front case half. Snapped the back on and checked for position of stem hole in movement to case--Amazingly, it was a straight clear shot right into the movement, so I tried the Accutron stem, all good! Out it all came again, so cleaned everything and securely soldered both the spacer-rings together, making one solid part. I then fitted the running movement to the spacer combo after flux and excess solder removed, and reattached the dial with a small amount of double-sided tape, that strong very thin stuff. Only issue now was the hands. The original Hamilton ones are all too big for the Accutron movement, so until I find a solution, I took the original straight gold hands from the mens donor Accutron and cut them to size, fitted them and reassembled back to the case. If you didnt know what a Hamilton Ventura or Pacer is supposed to look like, I guess you wouldnt tell, Its not too bad. The stem proved a Lot easier than I first thought. I shortened the mens case stem and again surprisingly, the Hamilton crown fitted perfectly. Its running now and will take some pics when I strip it all out again to clean the case and crystal, but its nice to wear this frankenstein love-child of two arch rival American watch makers.... --It even has kept time more or less to the second too! Anyone any ideas how I can source or modify hands to fit the Accutron movement so to re gain its correct appearance?

From Esslinger website: This special purpose Moebius grease contains Molybdenum disulphide to enhance it lubricity and resistance to pressure. It is designed for use on automatic mainsprings, to ensure proper functioning of the bridle. It is also recommended for use on the Bulova Accutron watch movements. Moebius 8201 natural watch grease lubricant Contains Molybdenum disulphide -------- I use this.

@JohnR725Thanks for the great download! I'll spend time with it. I guess I was a little light on the oiling by using the wire oiler without another conventional oiler first. I did see oil in the recess. But I will know in the future that the wire is more of a finish step to draw the oil onto the cap. At least that what I think I'm picking up from your comments. Thanks for clearing that up. On the Moebius oils, I just replaced some rather old Nye oil that I've had. I was using the 9010 for all wheels except the center wheel, on which I'm using the Synt-HP 1300. I hope that's not a terrible thing. It seemed to make sense to me. So the train in an Accutron is under more pressure, thereby requiring the 9020 oil? I was under the impression that there was less pressure in the Accutron. It's probably a good thing I don't work on watches for a living. I seem to remember reading that Samantha had worked at Bulova, I just wasn't certain. Thanks. Cheers.

I understand this seems to be a common problem related to the canon. Does anyone have any advice or a link to a manual or diagram that can explain how to fix this? the watch gums fine and when setting it the hour and minute hands move correctly.

Hi all.. I recently purchased the above watch with 221 movement for my daughter. Everything works, but as expected it runs fast. Does anyone know of anyone in the UK that can sort this out? It's a lovely, clean example that should be worn (if it can tell the time) Thanks in advance

I bought a fully restored Bulova accutron spaceview 214 a couple of months ago. A beautiful watch with an amazing history. The hands started to fail by not turning, and once i give it a small shake, it starts working again. Even though the hands stop moving, i can still hear it humming. I thought it might be the battery dying, so i changed it with the recommended accucell-1 1.35 silver oxide battery. Unfortunately as before i face the same problem again, it works for a couple of hours and then it just stops until i give it a light touch or shake. I would appreciate it if you could help shed some light on this issue and how i can go about resolving it, thank you.

The Accutron Bullova Caravelle case parts catalog doesn't seem to have that number listed, it could be the watch was released after the last catalog was printed (1979).

In 2011, while still in college, I was watching modern marvels one Sunday, and a short segment about the Accutron came on. I was intrigued, yet never really was a watch person. I saved up and bought a 214 hope it to later convert it to a Spaceview. Since then I have been repairing all types of watches, especially Accutrons. My most recents are an Electroquartz and Ultraquartz. I have no formal training, but love new challenges. If you ever have Accutron questions, I may be able to answer them!

Hello everyone! I hope this message finds you all healthy and well! So I was having a look at some watches I recently acquired, both Bulova’s with date codes of M6 (1966). The 2 I was comparing were a Surf King and an Accutron. So both watches have luminous hands and dials, but I noticed the Surf King had “T” markings indicating tritium but the Accutron does not have any markings indicating lime material. Now with both watches being from 1966 I would assume the Accutron is tritium as well. I doing some more research, I find the Accutron is made in the USA and the Surf King has “SWISS” between the T’s. So I’m just curious, would the US and Swiss have different requirements as to the markings of their dials? Any thoughts would be appreciated!

This was an odd repair. Had a screw loose within the movement from the rotor gear plate. It was jammed under the Balance wheel preventing it from moving and likely would shake loose from time to time. I got it out and screwed it back in place: correctly and sealed the back and cleaned it up. Ready and working. Sent from my iPhone using Tapatalk Pro

Hello @VWatchie, If I understand your situation (and I am not sure I do), I believe what you are experiencing is a timepiece that is not providing the expected isochronous timekeeping that you seem (I think) to feel that a fine watch "should" provide: https://www.google.com/search?q=isochronous+meaning (please forgive me if you are already well-accomplished in this aspect of horology) One of the reasons why time pieces are tested in (typically) six positions (DU, DD, PU, PD, PL, PR) is the very real fact that their consistency of their timekeeping (isochronism) is heavily constrained by certain expected physical characteristics and demand requirements, one of which is that the time piece must at least satisfy minimum Display requirements. In other words, the watch needs to enable the observer to be able to "tell the time" - which, interestingly, is one of the criteria that you mention in your above message as being almost trivial...considering your access to both digital and atomic time keeping. A design expectation for watches is that the Display must offer a minimum visibility to the wearer when they need it and are looking at it. In the modern era (and especially with respect to wrist watches) the movement is not in the position we typically need it to assume when we want to "tell the time". For most people, the device is mounted on the wrist in such a way that you need to raise your arm to look at its Dial, at which point the device (hopefully) tells you the accurate time. Your beef is that this is not happening. You are not getting "the accurate time". This is a claim (I think) that the isochronism of your mechanical wristwatch becomes unreliable when you are vigorously moving about. Most wrist watches are not designed to handle situations you are putting your wristwatch in, where it is being subjected to the kind of physical forces that you might generate in while working out. Interestingly, I have read recently about how sub-par isochronism might be somewhat self-cancelling through the random motions we generate as we move through the day. Obviously that is not happening for you. Part of this is the rhythmic and regular motions that a workout might produce. This will certainly wind an automatic watch. It may also be affecting the supplementary arc of your movement in ways you do not desire, amplifying the beat in one direction suppressing it in another. According to my understanding, Breguet came up with the Overcoil in an attempt to enhance isochronism, and I would also classify his Torbillon as another attempt to make the isochrononism of split balance time pieces more reliable, and of time pieces in general through another degree of mechanical isolation. In my studies, I have not (yet) seen a mechanical escapement designed in such a way as to be isochronous in an environment characterized by high-G. Temperature - yes. Humidity - Yes. High-G? Not yet. My suspicion is, if that research was ever performed, it would have been performed with escapements that are not purely mechanical in nature due to the inherent limits placed upon us by the Swiss Lever (and others) escapements. My instincts tell me that electro-mechanical escapements have a natural advantage in both high-G and No-G environments. This may help to explain the presence of the Accutron "Tuning Fork" movement in various facets of the Space Program (SR-71 control panel, Apollo control panel, Satellites & Astronaut watches). If you wanted a High-G/No-G resistant isochronous movement, my suspicion would be that it would need to be mounted somehow on a gyroscope - and I do not know personally how well a gyroscope handles instantaneous changes in direction. My guess is the gyroscope would fail. I also believe that there are serious limitations to the use of the Archimidean Spiral in High-G/No-G environments. I welcome any observations and insights from other members regarding the above. But you have a happy alternative: Buy yourself a Timex Ironman Triathlon, which seems to have been purpose-built for your design question. I myself used them for over a decade while engaging in armored combat, which is a very high-force and very fun pastime. My examples kept time just fine. I just had to change them yearly because the case eventually broke due to being rained with blows...even through the armor. But they still kept the time. As you can probably guess, I find this aspect of Horology fascinating, and I could go on further - but I've not got the time (right now) as I am working on a project that uses extremely high-precision clocks to instantaneously determine the origin of specific sound signatures in an urban environment in a Public Safety context. g. ---

I just received a Timex Electronic in the mail a couple of days ago. It still had the original Timex Type A battery inside. But luckily it hadn't leaked. The hand setting is fine, but the day/date function seems to be stuck. The balance is able to swing freely. A quick test with my Accutron test meter shows that the coil is still ok. How is this movement different from the Timex Electric? At 1st glace it looks identical. How do I get to the calendar works? Do I need to pry open the dial tabs to get the dial off? I hate doing that. I just can't get the dial factory tight again. Thanks in advance.

I've owned this "Accutron" branded chronograph for quite a few years. It's had numerous battery replacements. Last years, I the 1/100 hand stopped resetting (the other hands reset fine). Last month, it stopped completely and I thought that the battery was dead. I put in a new battery and it is still dead in the water. This blog entry about the watch says is uses the ETA 251-282 movement https://robswatches.wordpress.com/2011/06/21/bulova-chronograph-2006/#comment-648 From what I find, that movement does not have a date. Some pictures of my movement, which appears to read 251-292 I've found two similar movements: http://www.startimesupply.com/merchant2/merchant.mvc?Screen=PROD&Product_Code=ETA251292-4S&Category_Code=09-Movements And http://www.startimesupply.com/merchant2/merchant.mvc?Screen=PROD&Product_Code=ETA251294-4A&Category_Code=09-Movements Will either work? Star Time Supply won't sell to a hobbyist, is there another retailer that sells this movement? I found this one on Ebay, sold by a Greece seller. It does have the date at 4 O'clock: https://www.ebay.com/itm/ETA-251-292-Genuine-Movement-251-292-Quartz-251292-Date-at-4-white-dial-NEW/263427762010?hash=item3d5584a75a:g:NtYAAOSwHm5ZtpAJ I know the watch doesn't have great monetary value, but it was gift from my wife, so it has sentimental value Any advice is appreciated!

No need to scan the manual somebody else did it for us. I've attached the service manual a specification sheet and the bonus parts list. The reason I use the word bonus is that the parts list came with the boxes of the material. Siege to the various watches at least the tuning fork watches would have a box with a lot of envelopes and due to have these cards that showed you the parts. So here is where someone scanned in all the cards and made a nice PDF for us. I'm probably being nitpicky here but when I think multimeter I'm thinking analogue and if somebody use the word digital multimeter then the fluke would qualify. Accutron 218 --Manual.pdf Accutron Parts 214 218.pdf Accutron_Specifications.pdf

Regarding meters...it is not easy to find a 25ua analog meter. That is why I recently bought two accutron test sets because they use a rather large 25ua FS meter. I am planning on building a test platform using one of them. I know nothing about servicing accutron and don't plan to head that way...just hijacking this thread to add my thoughts on meters

Hi all, It's been a while since I posted anything here but tonight I was working on a watch and I thought there might be some interest in looking at it. The customer said the second hand would move but the hour and minute hands wouldn't. Usually that means the minute wheel assembly has became worn however today that part had became seized onto the center tube. Anyway I took a picture of what is under the dial of a 218 in case there was any interest. Notice the three springs that are laying about. The first time I tried working on one of these I lost every one of those things and maybe some of the other parts as well. I told my wife it was like trying to bait a mouse trap after you had already cocked it. Anyway I have this watch going now and here's what it looked like before. Charles K

I'd like to share a couple of watches I recently acquired ...... The first is a 1961 Hamilton T-403 Automatic . I had been on the lookout for this one for quite a while as they don't come up for sale very often . This one may be only the 1st or 2nd I've seen offered . It was offered by a professional watchmaker with 25 years at the bench , so the movement has been serviced by him . The case is a Gold filled Asymmetric design and I have seen this model referred to as the Shark owing to the fins of the case design . According to the seller , the watch came to him missing the crown so it has a generic replacement . The hour and minute hands are original . but the second hand was gold and "all - over wrong " in his words , so he replaced it with a second hand as close as possible to the original . The acrylic crystal is new . The movement is the same as used in Hamilton's Thin-O-Matic models , using a micro rotor for reduced Thickness . The dial is a gorgeous original finish with , un-noticeable really , a few tiny dots here and there . The Watch : Next is a beautiful 1965 14K and Stainless Steel Bulova Accutron 214 model watch . As soon as I saw it offered I knew I wanted to claim it , so I upped my Max Bid 3 times . It is a 100% original , fully serviced watch that the seller offered as a Solid Yellow 14K and Stainless 2-tone watch . I asked the seller why he offered it as 14K solid gold . His response was that the gold on the bezel is 14K solid Gold ,....So I dunno ?? Anyway ,....I had to have this beauty , and luckily for me , the bidding was not heavy . So here it is....

I found this definition quite interesting ACCUTRON stands for“ACCUracy through ElecTRONic. This would then mean that any basically electric watch would qualify including a quartz watch but I'm going to assume tuning fork watches what you're asking about . How easy are they? I suppose it depends on a variety of factors. For instance Bulova had an issue with the watch first came out as watchmakers didn't know what the make of this newfangled watch that didn't have a balance wheel. But that was also a generation of the watchmaker who didn't understand what to do with any of electric watches. So Bulova wasn't the only company with training for their electric watches. Although Bulova's certificate if you past was much nicer than everyone else's. Problem is their vintage and all vintage watches have a problem with parts availability and of course parts wearing out. Fortunately there is eBay where new old stock materializes from time to time. But I doubt that that's going to last forever so at some point in time there will be no more index wheels and circuits even if people are at least one person is rewinding the coils. Then there is the battery voltage issue work reverses silver cell. But there is a phasing procedure that seems to work well and then the watch will run at the right rate and still maintain current consumption within specifications. Frank basically if you have really good hand eye coordination because the fingers have to be absolutely perfect. It understand the test equipment the electronics part than servicing these is no different than any mechanical watch except. The exception is you do it be very careful on procedures of how things are disassembled and reassembled. Our Jeff to pay attention to where the fingers are when you're disassembling things 70 careful with the index wheel you can't just toss that in the place.

I have the accutron test set and one of the movement holders, so I am a little beyond the starting point.

Sorry, I missed that you had actually taken the course yourself. Heck, you must be older than me. Hopefully you don't FEEL older than I. As far as oiling those endstones that generally stay in the plate, I just bought an Horotec wire oiler that is made for getting through holes into shock-protection jewels, specifically Inca. It seems to work OK. I suspect you have the Bergeon automatic oiler(s)? I wonder if the Moebius oils with the UV activated coloration would be visible, and therefore helpful. I think that's what I bought last time for both 9010 and HP1300/9104, FWIW. Good luck with your Accutron. Cheers.

You talk about the notes jotted in the service manuals. I guess a lot of these were ones used by the students during the Accutron certification classes. There are a few notes in my 218 service manual relating to the sequence of setting the train wheels. I tried it the way the notes seem to say to do it but I found a sequence that worked better for me. I think I go Third wheel, fourth wheel, second wheel, index wheel. And while some say they have an easier time getting the pivots home by leaving off the lower fourth wheel jewel until after the other pivots are set, I found it easier having the jewel installed. Cheers. I'd sure love to attend one of those Frystack-type classes today. But his 214 presentation is certainly helpful, even applied to the other models. Presently I'm waiting on the service manual for the 221 series. I have one that's running and am considering trying to get it to run better, or at least without self-destructing. Heck. that's what it has me for.
