Hopefully this may be of use to someone.  It is a cheap and easy way to make the two tools needed fpr post or collet adjustment and it certainly works.  I decided to create the posting as a PDF and hopefully most people will find it ok.

Well done Vic! I have read some of your previous posts, but I wasn't too sure what you were trying to achieve. Thanks for clarifying, and thanks also for an excellent presentation. You know me, I love making or modifying tools. :)

Thanks George,

I am thinking about stripping away or cutting off some parts of a scrapper to get some pics of the index wheel with jewels in place to try and demystify some of the accutron oddities, but unfortunately I have other stuff calling me so it will have to go on the back burner.

I should have mentioned to folk not to use the tools straight away but give them a good clean before every use to get rid of any shavings, one of which would knack the index wheel action if it got into the teeth, blow air through the tubes and ultrasonic if necessary, demagnetise etc, I always have a quick look at mine under the scope.

I have to emphasise to all that I am in no way to be considered an expert on Accutrons but muddle along quite happily because I like them.

Cheers,

Vic

      Etachron regulation system

      By JohnR725 · Posted

      This conversation is becoming a very confusing. The etachron system is a very nice system for manufacturing watches. As you know it consists of two components the stud and the regulator pins. Beautiful thing of this system is you can open up your regulator pins center the hairspring and as you close the pins they will close equally on both sides providing you centered it in the first place. It's not like you're going to become closer to one side or the other as the definition of the regulator pins is a bit confusing it's not exactly a slot sort of. I'm thinking maybe a little eight reading will be helpful for you. Then the file name was changed by me at the US patent but the wording of Seiko may or may not actually be attached to it soared up? I just did that so I can find it in my files. Normally patents are in people's name if they work for a company the company name will be there you'll notice the person lives in Japan which is interesting as the name would imply that this is a Swiss product. Somewhere I think I have the patents for the stud and I believe that is Swiss like a lot of things their Japanese and Swiss and then the Japanese let the Swiss name stand as it seems you more popular in case as you read up on the patents of the regulator pins or pin will see and it should explain exactly how and why it works also why it's important to always close at an open in specific directions because the pins actually have a shaped to them it's very hard to see the shape as it's very tiny.   As a reminder with this system it's mass-produced. I wouldn't be at all surprised if they use cameras and computers to do all of the adjustments.  The meaning of this is that the majority of watches will function as there supposed to and do what they're supposed to do the system will allow us for some minor in tolerance and has more than likely as I said no human hand is ever touched those watches that's the way they left the factory and they work fine.

      These still seem stupid expensive for a bottle, but still £100 cheaper than than the Moebius ones. Anyone have any experience of these: https://www.cousinsuk.com/product/epilame-fixodrop-special-bottle-horotec

      I bought an old Bergeon 5555. The bottom of the tank was full of petrified salts, which also corroded the metal parts a bit. I would use just distilled water.

      INGERSOLL watch necklace - Unsure of make/model

      By EBUZZ · Posted

      Can anyone help me identify this watch/pendant. It was inherited by me from my grandmother and I am unsure as to what it is. It's a watch/necklace with a blue face with the inscription "INGERSOLL" and "Swiss Made". Have tried looking online but to no avail. If anyone knows a make/model or knows where I might be able to find out about it, that would be very helpful.
