Citizen 67-9119 cal.8110A "Spider"

Recommended Posts

Hello,

I started new project - Citizen 67-9119. It's seventies chronograph based on 8110A movement. Watch came to me as "fully working in great condition" As you can see there isn't crystal. The one which was here had chip and wasn't set properly in bezel so when i turned the watch it fall on the floor and broke. As you can see dial is in quite good condition, only it needs to be relumed. Hands needs to be repainted and relumed too. Movement works well but it is too speedy (  +3 min/24h). Chrono buttons work properly, only the hour counter stops at "3h" position so I must to take a look here. I striped down the watch and disassembled movement. There was some much oil everywhere so the cleaning is required.

Nice one! A lot of Citizen Chronos came in base metal cases... (especially the Mickey Mouse version with crown at 12) which don't survive very well.

Please share pics of the build-up!

 cleaned the movement parts and I have had first surprise - hour chrono axle fall out from wheel. So I tried to put it together again and I hope it will be ok. I think that this was cause of not working properly hour chrono counter.

Hello guys,

After two days testing movement on the bench it looks ok. Power reserve, day/date changing, accuracy something about +/- 15s/day. Now it's time to take care about dial and hands. Please let me know - what colour of chrono hands should be - orange or yellow? In the web I found pictures for both option so I am confused.

It looks like it was Yellow originally so I'd go with that.

When I look to the hands by loupe I can see that all hands was repaint in the past so it's hard to say what original color should be. I think I will choose orange one like often seems  in Citizen watches and the case will be satined. So stay tuned ;)

Hey folks,

I have two questions to ya:

1. What is your's experience about lubricating the pallet fork pivots and jewels? Are you doing it or not? Do you recommend it?

2. How properly lubricate the chronograph runner (horizontal clutch wheel) ?

Please share your expierience about this.

I don,t lubricate fork pivots. 

Most important are escape teeth-pallet interface, tremendous friction there.  I will be getting the recommended mobeous 941 or 9415 and expect reporting good results.

See the difference pallet lube makes for yourself, observe amplitude before and after pallet lube.

When movement was ticking in the drawel I could work on the hands and dial.  The old coat of paint was remove. I chose the paint that in my opinion is similar to the orginal Citizen orange color. When you paint so small parts you should have patient - no rush or you want start again ;) Hour and minute hands get white paint and new lume. I think it looks ok. Only with painting the dial I am not glad - it could be better. But it was my first time so I forgive myself ;)

Step by step to the end...

Thank you guys for your feedback.

I got an unplanned job today - some kind of surprise. I took out the chrono's pushers from the case cause I want to polished it and it turned out that there were no springs and gaskets on the pushers. So I twisted new springs from spring wire and set new gaskets. I did couple attempts until springs were ok. Now the pushers look and work like a charm . Another hours of works go on - I hope it's worth it  :D

I’ve never thought about repainting hands. May I ask how you did it? What paint you used, etc.?


Sent from my iPad using Tapatalk

I have used nail paint which color is similar to the orginal. It's not the best choice cause nail paint dry to fast but as you can see I did it and it looks good for me.

You can use an oiler to paint. The key to succsess is that paint should be runny and you have to do paint by one move.

I reach to the end of this project. Now it's time to take care of case and bezel. I brush front of the case and polish sides cause I like it that way. Bezel gets new paint coat of satin black acrylic. Here's some pics. Cheers

Great pictorial, thanks for sharing...you can dilute the nail polish with thinner to get it a bit more runny...however I would not recommend it as the fumes can damage the dial in time..

Personally I would get me some new hands on Ebay...

The different case as mentioned and the oxydized hands...did you get this one from Mumbay?

The final stretch - fitting new signed crown to the case and another surprise come - stem is too short about 2 mm for the new one. So I used the stem extender, couple measurements and cuts and voila - it's fitting and working perfect.

Works on this project are done. Here're the results below. It's my second project of the 8110A movement. I am very impressed about japanese design and engineering.

What was done:

- dissambly movement, cleaning, oiling

- repaint bezel and fit new glass

- repaint all hands

-relume hands

- new gaskets and springs for the pushers

- new signed crown

- little case polishing

- assemble

Now it's time to enjoy and wear it on the wrist. I'm verry happy cause this watch is small timepiece which fits to my narrow wrist just fantastic. Cheers

Re painting.  I have used acrylic on hands and dials with satisfaction, but found it could get damaged easy if used on case/bezel.  I tried a special matt black BBQ paint from local B&Q which was better on cases/bezels but still not very tough.  I eventually used a black epoxy aerosol paint of the bay, and this proves to be very tough.  It must be applied to a very clean surface and in light coats, allowing each coat to thoroughly dry/set, to build-up a good finish

      I have a UG Tri-Compax from the 1950s or 60s (Calibre 281): The chronograph (centre) seconds hand can’t turn past 58.5 seconds and the whole watch stops ticking/working (nothing moving/turning in the movement). However, when the reset pusher (4 o’clock) is kept pressed, it enables the seconds hand and watch to move/tick again. The reset pusher is released when the chrono seconds hand reaches 60: the watch resumes ticking and the hands move until the chrono seconds hand reaches 58.5s again. The process is repeated.
       
      It has been noticed that if the watch is held face down then the reset pusher “procedure” doesn’t always work (i.e. the watch does not resume ticking/moving). It’s usually necessary to turn the watch over and try to press the pusher a few times in order to make the seconds hands move again.
       
      The 30-minute sub-dial at 3 o’clock has stopped working, too.
       
      If the chrono is not activated, then the watch seems to run properly.
       
      What do you think is the problem?
       
      Thanks for your insight!

      Hello, everybody.
      I wanted to share my restoration stories that I have done for a long time and thrown into my archive. First I discussed the Atomic Mars 71 Brand using Valjoux 7734.
       
      As it was seen, scratch and dial is broken. To begin with, I tried to brush the Case as Brushed and make it the first day. If it is decorated, I polished and re-painted the indexes (with acrylic paint). I usually do this in three layers so that the paint is not deleted in a short time.
      I replaced the case buttons and tubes with aftermarket buttons.
      Since the condition of the dial was in very poor condition, I had it re-painted. The quality is not so good. In Turkey, unfortunately, not doing the job well.
      Caliber 7734 (Valjoux) is a special and robust mechanism for me. With good maintenance and lubrication, you can reduce deflection values up to 3-4 seconds per day. I added a short timelapse video about it :)
      As a result, such a result came before us.
      Thank you

      Hello guys,
      I want to show you my lately restoration project. This time it was a Seiko 7015-8000 with blue dial. Watch came to me in very poor condition. As you can see on photos the case was scratchty, crystal was totaly tarnished with deep scratches. Everywhere was dirt, gunk and mud...yuck. Movement was running and stopping with very low amplitude. After opened the caseback I wasn't suprised - it looked like as case - dirt and signs of wear. Rotor was loose and fall out the case. When I take off the crystall I saw dial which had faded Seiko logo, some scratches and hands which lost their lume.
       














       
      Next step was strip down the movement - everywhere dirt and dry old oil. Time to cleaning bath

       







       
      Look at this - it's my temporary balance wheel stand - I suspect that from temporary it will be permanent. It does job well.
       

       
      After cleaning it's time to assembly movement. Now it looks better - maybe not pristine but clean and shiny. New oil here and there and movement starts to run. Now it's time for bench testing before install it to the case.
       





       
       
      Meanwhile I took care of the case, dial and hands. Case got some polishing work - not to much cause I didn't want to loose the sharpness of edges. That is effect:
       





      Dial and hands got new lume - I am not perfect in this work but I still learn to do this. Additional the seconds hand was repainted to orange color. I didn't change the crystall but i just polished it with waterpaper and on the end polish paste. Effect suprissed me. Time for the  pleasant work - putting this all pieces together into the watch.

      Hello, 
      I have a j810 movement that needs a stem and crown. Can’t find part numbers. Citizen eco-drive j810-s088232.

      Hello everybody,

      I open this thread to archive works on Citizen 8110A Bullhead. I purchased this watch in poor condition as You can see on the photos.


      Cause I have serviced few chronographs in the past I decide to try restore this watch. Maybe is not ractional from the economical aspect but we do this because we love it So let's open it.

      Hands are in good condition (required repaint and relume) but the dial has broken legs and tachy scale is faded :/ I think it's really hard to find orginal and there is no gold aftermarket replacement - sad. Look at the movement.







       
      Gosh, what a dirty place It needs good cleaning and oiling. 
      But the biggest problems are this.


       
      Broken post on main spring bridge and missing rocking bar core and screw in gear train. I need to find replacement.

      While I'll be working on movement the case and pushers are send to renew - putting new gold plated coat

       

      Stay tuned

    • Thank you guys  Little bit apprehensive, as I have only ever fully dismantled and rebuilt a pocket watch movement, but I do want to try.  much appreciated as always.   
    • It’s funny how people manage when working with watch movements or anything tiny. I wear glasses all the time. When I was working on watches I would take my glasses off and use an eye glass, I couldn't stand one of those flip down eye glass that fix to your frames it was like looking through bifocals.
    • This is also often asked. It's common for ball bearings to be a bit lose or noisy, especially after decades of use without any lubrication. The screw has not effect whatsoever as it's there to just keep it in place. As long the weight doesn't touch anywhere, and the watch winds, all is good.
    • jdm has saved me from writing up. Just to say that hairspring is in a right old mess. 
    • First, the hairsping in the picture is unacceptably distorted, many topics on the subject of correcting an HS and the difficulty of the task - high. If you want to show how an HS looks like, remove cock, lay it down and shoot from above. Then, fault finding consist of taking the entire mov't apart, clean it the best possible, inspect every part under magnification, pivots, jewel, gear teeth for damage. Put it back in the most basic form and test every function, end shake of every wheel  etc. You can do that even without oiling because it will run anyway, not perfectly but it must not stop. Again, the forum has many many repetitive threads, which will tell you always the same things, just as any book would.
