I just picked up this Accutron last weekend at an estate sale. This is my first and have a question. It is not running and I'm assuming the battery needs replaced of which I have ordered. It is a 218 movement. Am I OK to just install the battery and see if it works or should I completely service it before installing the battery?

From what I've read accutrons are not straight forward services, i believe a watchmaking book of mine told me that eyeglasses weren't sufficient, that you needed a microscope for a couple of the pieces including a wheel with 300 something tiny teeth. I'm only aware of one place that commercially works on them in the UK. 

I think minimum intervention is the key here.

I'm with Swordfish and Ishma. Install a new battery. If it works, you're good.

If it doesn't work, place it up to your ear and listen: If you hear a hum, then the coils are good, and it might be worth your while to service. If there is nothing, then the coil(s) will need to be Replaced$.

If you replace the battery and it doesn't burst into life, hold the watch tightly face up and give it a bump with the heal of your other hand in either the 9:00 or 3:00 position.  This will often get them going as it can start the tuning fork vibrating.

If it starts the watch, it could just be needing a service.

If this doesn't it wil definately need a service and/or repair.

   When you put in the battery , [Negative side up ] , and it runs , all is good . If nothing happens , tap it at 9 or 3 o'clock as Geo suggests . It may run , or just the second hand will move , or it may just start to hum ,....all good signs that the coils are good . If it just humms  or just the second hand moves it will require a service  .

It should probably be serviced any way , but not a job for the feint-hearted ....There is a place advertised on ebay that does flat rate service on Accutrons ....Star findings I believe .

Here is the link for the Accutron page which is a plethora of Accutronism .....

Here is where you would test the coils with a volt / ohm meter ....

Good luck......

Accutrons are not for the faint of heart.  My father gave me his Bulova which he received as a wedding gift from his parents and it also wasn't working.  I popped in a new battery and it came to life except that the hour and minute hands don't move.  From what I understand, rusty cannon pinions are common which result in a watch that appears to run, the hour and minute hands just won't move.

I've looked under the microscope and there are two jeweled pawls that contact a wheel with the tiniest teeth you will ever see (it really is the most amazing mechanical watch), well long story short, I've had it in my desk now for about six months and still don't have the courage to attempt a service. 

I do have a PDF of the 218 service manual if you need it though.  It's readily available on the internet although I cannot recall the site I located it from.  Also have about fifty Accutron crystals too.  Let me know if you need one and I'll drop one in the post for you.

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?

      Movement holder made with 3D printer

      By Waggy · Posted

      hmmmm.... maybe there is a way to skin that cat 🙀 let me think on it... unless anyone else has any ideas? I left the opening in the side of the base and ring quite large to maybe allow you to grip the crown, but appreciate this may not always be possible, especially for small movements where the crown will not extend past the outer wall of the holder. I noticed this also, but after using the holder for a while I noticed that the ring/holder began to wear into shape (rough edges/bumps worn off) and the size became closer to the desired movement OD. Maybe with some trial and error we could add 0.5 mm (??) to the movement OD to allow for this initial bedding-in?

      Vintage pocket watches from e-bay (winding stems needed)

      By Mallard · Posted

      Hi nickelsilver, thanks for the great explanation and the links! I'll take a good look in the article.  Especially this is great news to hear! Looking through forums and youtube videos I was informed to 'fist find a case and then fit a movement for it'. But seems that's not the case for pocket watches at least?  I guess I should be looking to find some 'male square bench keys' for now. I was thinking of winding the mainspring using a screwdriver directly, but I found a thread that you've replied on, saying that it could damage the spring.

      Murks, The rate and amplitude look OK, and the amplitude should improve once the oils you have used get a chance to move bed-in, also I notice that you are using default 52 degrees for the lift angle, if you get the real lift angle (assuming it's not actually 52) this will change your amplitude - maybe higher, maybe lower. I notice that the beat error is a little high, but not crazy high. At the risk of upsetting the purists, if the balance has an adjustment arm I would go ahead and try and get this <0.3 ms, but if it does not have an adjustable arm then I would probably leave well alone. Just my opinion.

      Epilame / Fixodrop

      By Waggy · Posted

      Maybe I'm over simplifying this and I'm a little late to the discussion, but just by my looking at oil when I use it on a treated cap jewel  the oil stays in one nice bubble, but when I don't it spreads out to the edges of the jewel. I'm not sure (but could well be wrong) but the analogy of a waxed car and rain is accurate in this case, the wax is very hydrophobic and repels the water, however, the process epilame works by is a different physical process based upon cohesion/adhesion (oleophilic) not repulsion (oleophobic)  at least as far as I have read/observed. If one were to use a oleophobic substance equivalent to wax (hydrophobic) then one would need to create a donut shape to fence in the oil, however if one used such a strategy with a epilame which is oleophilic then the oil would sit on the ring of the donut and not in the 'donut hole', exactly where you don't want it. Even if the oil is smeared then the oleophilic epilame should pull it back to the center (see diagram below). Reference For interest the chemical in epilame is 2-(PERFLUOROHEXYL) ETHYL METHACRYLATE, CAS NO: 2144-53-8
