Very helpful, excellently illustrated article.

Am I right in thinking that I would be unable undertake a coil replacement without test gear for re-indexing after reassembly (and no experience of this). I live in the UK.

Kind regards,

Malcolm Davies

Yes there is interest and it will at least be steady or even rise.
People need to learn about the history and fascinating technique behind these watches. I've already infected two of my colleagues who first thought my watch is just another swatch or something, now one has bought one already and the other one is looking out for one. I've already dissambled two movements and try to educate myself right now to get them clean and running again, which is quite difficult as I only have basic knowledge of electromechanic but I will get there.

Thanks for your efforts and for your pages.

Robert, you wrote - "I plan to do a good job even though there doesn't seem to be much interest in it. I think my article on a cheap little pencil sharpener garnered more of a response than these do..."

Oh, there is interest. It's just that your post here isn't easy to find or fall across. I'm an Accutron collector from California, and have been reading this with interest. I've acquired some of the specialized tools and would love to learn to service my own collection. It's a daunting task, but I'm about ready to "dive into the deep side of the pool." Robert, head on over to the Accutron/Bulova/Caravelle subforum at watchtalkforums.com for some fellow enthusiasts (if you haven't you haven't already). Eric (ArchieGoodwin at the forum)

Hi Albert,

It wouldn't surprise me if they sold the patent to Japan. I believe Japan had the most favored nation status from the USA at that time.
As far as the scope is concerned, I'll do my best. I also plan on some video with my microscope camera. I purchased a Bulova Accutron Power Supply 9920/6604 that should be here next week. I was going to build my own, but this one presented itself and it looks really nice. You'll see it in the photos. It uses a 9V battery. I've also acquired an Accutron Watchmaster Model 700, but I probably won't use it for this 214. It is mainly for my 2182's, etc. It is in immaculate condition and I consider myself fortunate to have found it before someone else grabbed it!
I plan to do a good job even though there doesn't seem to be much interest in it. I think my article on a cheap little pencil sharpener garnered more of a response than these do...

It indeed must be a very complex process to make such tiny wires Robert. I read that the US patent of making transistors was sold to Tokyo Telecommunications in Japan already in 1955, later renamed to Sony as the company started to make battery powered 5 transistor AM radios. https://www.wired.com/2009/08/dayintech_0807/
Which is rather strange knowing the transistor was just invented in 1947 and very promising. And that it was a great invention I can read back in a very old book I have (published in March 1959, the year I was born in) with the title: TM 11-690_Department of the army technical manual - Headquarters, department of the army. (with a stamp on the cover saying: United states of America-War office). And in that respect a bit odd because it was only about 14 years after Pearl Harbor and just 10 years after WWII.
Like you I do not own very expensive equipment, but I do count my Tektronix 2465 and 2440 oscilloscopes to my most expensive devices.
I am curious if you are able to manage in making some oscilloscope pictures of your Bulova in action! And with what equipment if you do. Which would make it even more interesting to us electronics guys.
Thanks!

Thanks Arthur. I like having a watch that I can look at without using my cell phone. My eyes aren't very good. I wear glasses. I have a pretty good stereo microscope. This would be impossible for me without a good stereo microscope.
