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.

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.

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.

      I did not. I thought about it, but I had cleaned it in my ultrasonic, and the tech sheet shows lubricating it in place already assembled, so I figured discretion was the better part of valor. Although since I have to depth the jewels anyway, maybe I pull the pinion off to rule it out 100% as part of the problem. Do you know if there's a safe way to do it? I don't want to use a puller because it would push down on the plane of the wheel, and that seems like a Bad Idea. I thought about using a roller table remover, but I don't think I have a hole stake pointy enough to push it down.
