OK...more like a "place" than a "center."

I will be spending half my time here, so I needed some way to do horology. Since Accutrons need a subset of my tools, and I have about 50 to work on, I decided that I could setup to do just Accutrons here. I still need a cleaning setup...working on that!

I have the microscope, test set, and the hand tools.

Today, I took an Accutron that was not working, opened it up, adjusted the index and got it running. It needs a cleaning, but I was proving the tool set to see if anything was missing.

Hopefully I will solve the cleaning methodology over the next couple of weeks.

This seems to be the only one available at the moment. Price is a bit high.

I have a few 214s in the group, but am pushing them to the end of the cycle. Will definitely lean on you guys to help me... appreciate you guys so much!!

I take it you have a copy of Fried's second edition? He details the 214 and 218 (pages 103 and 134, respectively). There might be more recent documentation.

Is it running? This is a very interesting watch getting parts for it is extremely difficult plus you really should have the service manual do you have the service manual?

25uA meters are kinda rare

They show up on eBay occasionally very occasionally. Analog meters seem to be a thing of the past and getting a really nice analog meter is rather difficult now as nobody seems to be selling them anymore except on the eBay.

This is why even Bulova in their factory service used an amplifier for their meter.

 No its  not , bought it as a non runner, and suspect  some watch destroyer has been at it, perhaps should tag it as a donor, but I wouldn't know which part is good which bad .

The picture I posted is from internet, mine doesn't look half as good.

Did you notice the specifications for your 25 µA meter? It's a plus or minus meter it's not a 0 to 25 kind of. EBay is still a nice place to get meters if you're patient anticipating someday I might build a new power supply I managed to get a 0 to 20 µA meter who knows where though it is lurking in the house they purchased a while back.

The other source of service manuals for Accutron Is it just download the PDF's as the book is basically a copy of the service manual anyway. The link below has all sorts of interesting Bulova stuff with all of the tuning fork service males etc. found basically at the bottom of the page

It's a shame about the running aspect because when it's running it's really interesting it's not your usual tuning fork watch. I don't suppose you ever looked up and looked at the inside of it? It's quite interesting was very different than the tuning fork watches were currently discussing like no need the phase it's been done by the factory it either works or it doesn't. Then a course everything else has to be right the gears are really interesting very interesting which will make no sense at all unless you actually have seen the picture of the inside of this watch or you have the service manual

      I just poked an inflation calculator, and $5 in 2020 would be about $6 in 2024. Doesn't fit very neatly into any status codes, which stop at 5XX, but that's honestly somewhat arbitrary outside of a clever pun for those that dabble in such things. Back during the pandemic, I would spend a good chunk of idle time in the evenings scanning through hundreds of listings a night, and I would only land 1-2 a week max. I would often go months without finding something suitable. A very small percentage of the watches in the price range are worth pulling the trigger on for my purposes. The number floating through the thread here may be somewhat deceptive.

      Balance cock stud screw

      By Zedster · Posted

      Hi, guys I got there in the end after several attempts using a screwdriver and Rodico, I couldn't wait for the tool to arrive and was getting pretty confident handling the stud screw without it flying away. At first, I was using far too much Rodico, and then realized you only need the smallest amount inside the screw slot. Putting the cock back onto the movement also helped as it gave me more to hold onto while my shaky hand tried to align the screw wobbling away at the end of the screwdriver😁 Anyway, job done and I can move on. Thanks again for all the advice it's really appreciated for a beginner.

      the escape wheel can't move itself

      By nevenbekriev · Posted

      You need to know at least the basics. Then the questions that You ask will begin to make sense. From what is seen on the video, the gear train and escapement look fine, but the balance doesn't rotate free. I can suppose that the thin gold colored shim that must stay under the balance cock is not in place.

      Waltham A-11 Hairspring and Balance assessment help needed.

      By nevenbekriev · Posted

      Yes, there are a lot of shapes and all of them are used in different cases. The one in Waltham A11 is one of the most spreaded and is what I have shown in the beginning. Of course, the radius of the final curve will depend on the distance between the hole in the stone and the regulator pins on the cock
