    Great explanations of the work you're doing, and cool shots too, 31j. How does a balance wheel get bent - is it most likely rough handling by a 'botch maker'?

    Thank you.
    Yea, pretty much. Or putting the movement in the wrong holder/picking it up wrong and bending the balance with fingers.
    The watches i get are all 40-100 plus years old. And like a car, there have been (alot) of other hands in it.
    Most of my work is fixing mistakes made by men who have probably died by now, or ones that didnt have any formal training or education in watchmaking or repair. I would say for me, the ratio is 1 in 20 watches that are pristine. I can tell when a watch was handled/serviced correctly in the past. 31

    Hi Wysanz,
    I've been exchanging information with 31 Jewels about Citizen's vintage chronographs, including the 67-9151 he's restoring at the moment. I have one of these and the case number is 4-901118, whilst Brian's is 4-901142. Both of ours have dial codes of 901204, which I think is the same as yours. Would you be kind enough to confirm the numbers on yours? This would be helpful to Brian and for my blog, where I've done a page on the chronographs.

    Can I ask as well for some info on the two 67-9178s you have? I have the black dialled version, but the dial code is missing - the dial must have had some issues in the past and has been painted round the edge, losing the second indices and the code. It would be helpful to know the dial codes for both models, so I can add them to the blog page so it's as complete as possible.

    Sorry to trouble you, but I hope you can help,

    All the best,
    Stephen aka Morris Minor and Sweephand

    Yes Stephen, The dial code on my 67-9151 is Japan 8110-901204 KA, and on the case back the Ref.No is 4-901118 Y, mine and yours have the same codes.
    Here are the pics that I took today, I post them here just to share.


    As for the 67-9178, The codes are 901239 KA and 901221 KA respectively for the black and white dialed versions.




    and the case back...
    Hope it helps. Cheers!

    Hi wysanz, thank you so much for your reply and superb pics! I'm sorry I'm late replying to this, I didn't get a notification about your post so missed it. The 67-9178 info is just what I needed to complete that entry on my blog page.

    And you have 2 white dialled 67-91678s! Boy am I green with envy

    All the best,
    Stephen

Size:  125.7 KBEarlier in the thread i had mentioned that i was missing 2 key pieces to my Citizen 67-9151. I have discussed in my other restoration and service threads about Citizen 8110 movement holders. Some models use plastic ones and some use metal ones with screws and clamps. Well, this watch's metal movement holder was missing. My first thought was crap. Where am i going to get a very important rare part for this watch. I know what you might be thinking. Just buy a parts Citizen 8110a watch to get one.Name:  014.JPG

Size:  157.3 KB Easy enough, so i buy 3. Any of these models look familiar? I bought these for one thing. The metal movement holder and the 2 clamps and 2 screws. But, there was a problem. The single registers here i just tried to fit the whole movement in the 67-7151's case. Guess what? It wouldnt fit. How is that possible? I can explain later. So i then buy a Bull Head. Restoring Vsansbajo's, i learned that these too came with metal movement holders. Ok, so it fits in the 67-9151's case, but not in the case back. So, this is what i did.......
