Hello watchmakers!

I am about to work on a vintage citizen watch.

I removed the movement from the case but I am stuck on removing the automatic rotor..

It seems that my screwdrivers won't do the job..

Any advice would be helpful thank you.

The tool needed to remove the nut is described in that second PDF, around page 32 in my PDF reader.

You should be able to make something similar relatively easily from a piece of round stock, perhaps an old screwdriver blade with sufficient meat on it, by cutting a suitable slot in the flattened end.

Note the direction that it tells you to turn the tool. That sounds like a standard thread rather than a reverse one. Normally it is lefty, loosey, righty, tighty. i.e. Anticlockwise to undo and clockwise to tighten.

 

I would take the time to make the tool, as otherwise you risk marring the end of the "nut" on the weight.

I use an old bronze tweezer . Hold it over and use the left hand to press around when unscrewing . have worked for me so far. But as i saw the picture of the tool. I wonder if i don't have a screwdriver here that is for that . Always wonder what it was for. I will go and have a look.

Found the tool . But couldn't find the movement right now . Is the nut approx 2,1 mm .  The citizen i had in was a 52 -.... diver . Which i thought should have a movement with such nut. But it had a normal 8200  movement. Great for me as i found those movement a pain to service. 5270 and 7270 isn't that the numbers. Have 200 clicksprings on the date mechanism :)

I found one on eBay that worked perfectly fine at a very reasonable price.

Nothing else I tried worked!

Good luck.

Just grind a slot into a piece of metal.. I used the clip from a pen... use like you would a spanner/wrench.

It was for the Citizen rotor screw . How would have know that ? DSC00350.thumb.JPG.bee28b023f7384169d8422a0f6dd5071.JPGDSC00351.thumb.JPG.7b506236201b1ac09956eaad44d31496.JPG

This is how i did before. You can hold a little closer to the screw with your fingers. DSC00353.thumb.JPG.a1c3174f792df9075a15a2e792c445ba.JPGDSC00352.thumb.JPG.b912163308d132f5783276c40062f5f7.JPG

Hey guys! Just wanted to thank you because of you guys sharing all this information I got to put back a similar citizen for my dad!
I did not find any info on the movement (maybe did not use the right words) so took the thing apart blindly.... But just before putting back together I found this thread and got the manual someone shared! Thanks a lot.

      Hi guys. @VWatchie Those images are self hosted (not hosted on this server). Do a look at the page source and you will see this. I’m afraid, I can’t have control or backup images not hosted on this server. ( They seem to be served from here: https://qehvsw.bn.files.1drv.com/) This server is backed up fully every night and the database is backed up and versioned every hour, all stored off site on Amazon S1 platform. It’s hard for us to lose data. Ive got a huge overhead of space on this particular server the site is served from so no worries there 🙂 Sorry all for lack of response so far, I have been extremely busy and am embarrassed to say that priorities had to be set in place for a while.  Be assured that i’ve got constant monitoring and alerts should the site be in an extended problematic state (down etc) and work on these issues if they arise.

      Web sites are cheap. Message board are easy. Hosting both is less than 100 usd a year and small advertising would cover most of that.  In the discord group we did some 15 min poc and threw up a couple of different message boards on a domain i host.   The real value is the data / information / hive mind While I'm a rank amateur in watch repair the information and assistance on this board is invaluable. The members on here are friendly, entertaining and a wealth of knowledge This is what needs to be preserved  --Jeff

      HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....
