Greeting all. Does anyone have any suggestions on how to deal with a rather unusual capped escape jewel design on a little Bulova 6CLC? It was suggested that, with the proper tool, the retainer might thread out. This makes sense, but I've never seen such a tool. The 3-prong Kif tools are all too big to be of any help. Thanks in advance. Cheers.

I was informed that this type of jewel is friction fit, and not meant to be removed. The "spokes" that look like they'd take a special tool are in reality vents to assist in cleaning and drying. So there you have it. Cheers.

I agree with the above statement. If you look at the image I snipped out of your image notice that your jewel has something peculiar or specifically the setting. Notice in three separate locations there's openings? I reasonably sure that the purpose of those openings are to allow the cleaning fluid to penetrate and go between the hole jewel and the end stone. Otherwise if it was your normal jewel you never get the cleaning fluids in.

I guess I just thought more highly of Bulova than that. A cap jewel on an escape wheel without one on the center wheel is blatant jewel count inflation. Kinda disappointing.

Everybody did it then (and now?). Only issue I have is after 40 x years even the best solutions in a 13k bucks machine doesn't get all traces of old oil. The design is good, modern cleaning methods should be ok. But you can't see it. I have one of those 13k machines and change fluids very frequently, and regularly have remnants on certain jewels. Especially vintage pieces- and I often preclean with benzine! For a piece like this I'd say 2 trips in a "classic" machine for sure. Avoids amplitude questions later haha.

What do you find odd about this? 

Nothing aside from the fact that I'd never seen one like it. If they are common, it may just be that I don't get out much, i.e., haven't worked on that many wrist-watches.

And yes, that jewel "kit" is indeed on the escape wheel, and does have a cap jewel. Many thanks, all. Cheers.

      Ok so there is barely any response happening . After this last attempt i think I'm just going to give up on it because very few seem genuinely interested or even bothered or worried what may happen in the future. ( if someone can set me straight I'd love to hear it ) I would think anyone into watches has heard of Roland Ranfft, how they grew to love and depend upon his site for detailed information. And not just that, he also had a view about Ebay and everyone that visited Roland's site knew exactly what he thought about Ebay, Roland's site also had a secondhand watch sale side to it.  If anyone here could have done anything to preserve his site and keep it exactly the way it was.........Would you have done something to make that happen ?  Its been pointed out to me but not in so many words  that I'm probably coming across as an insensitive p.rick, truly I'm sorry about that, i say it as it is but no malice is intended and yes clearly I'm putting my forum membership on the line here. I'll happily shut up about it now, I've done all i can.

      Thank you so much for posting this!  Although this movement is serviceable, there are no service notes that I've been able to find.  This is a great alternative!

      Greetings from another electronics designer & programmer!   I suggest you get a batch of similar scrap movements from ebay - I found batches of Seikos very cheaply, I got seven of one type for £11 (or 11 Euros possibly?). Those were ladies, 4206B I believe. There are also mens movements at a slightly higher price; eg. https://www.ebay.co.uk/itm/134723051997 https://www.ebay.co.uk/itm/235565276549 They are cheap enough so it does not matter what gets messed up or lost & you can probably still get one or two working movements from a batch, even if some part are damaged when you get them. (I've had quite a bit from the guy in Holland, he usually has a good range of movements).

      Please OH, we should all be proud of our collections what ever they are. If we can't show them off here then we can't show them anywhere. Our favourite gives us a story to tell of why we love it, that story also tells others something about ourselves. These are some of the things that make our forum and our community so amazing .

      I can take pictures when I am home of what it looks like.  They will be phone picture as I don't have a camera in my microscope yet but I should be able to take a few views to give a good idea of the damage.
