      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 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.

      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

      Hey everyone, I cant find out how to get this drown off and I've tried everything. The Miyota JS25 movement says PUSH and points to a hole which I've learned means this is where you press to reease the crown but I still can't get the crown out no matter which position the crown is in. I first tried with the crown all the way out then with it halfway in, then all the way in and haven't been able to get it out, please help.

    • The only markings on the movement are the words Swiss Made, 15 Jewels and a small 5 under the balance arm. I don't currently have a very accurate caliper but I think it is 34.7mm rather than 36.4 as the Unitas 6497 movement wouldn't fit. Here is a picture of the dial side but I haven't seen any writing on it. I do not believe that the movement has ever been changed since it was made in around the 1930s.  
    • I have a nice little carriage clock in for service, very good shape, except for over 0.30mm sideshake of the barrel arbor in the barrel. Thought I would show how I bush these; it seems they often get overlooked or just skipped as they are a little more fussy than just bushing a plate. I measure everything up, then remove the boss in the barrel, and make a bushing that fits from the inside and is stepped, replacing the boss. This way it's captive, and doesn't require a big interference fit to get seated and stay. I turn up the bushing with a boring tool in the lathe, doing the outside as well (running in reverse of course), then do the barrel opening with the same tool. It's a pretty quick process once you have the moves down!    
    • Well the movement is Unitas, but they did make many many different calibers. What is the exact diameter of the movement, and can you get a pic of the dial side? Are there no markings near the balance cock or on the dial side? If not it will take some digging but you will probably find it on Ranfft's site.
    • I must admit I have never even clapped eyes on one like that, but my gut feeling is that you back off the key in the opposite direction to winding, and it will unscrew, then undo the knurled bolt, and pull on it, and *something* should slide out of something else. The chances that I am completely wrong however are around 50% EDIT: Wow.. Barographs are expensive when new.. https://www.metcheck.co.uk/collections/barographs . I'll need to keep an eye out for one, they look pretty interesting, similar to  clockwork seismograph recorders .   
    • Thank you but I should have mentioned before, tried a Unitas 6497 clone movement to see if it was the correct size. The gears are far finer and the escape wheel teeth are the wrong size and it was slightly too short. It has a Swiss Lever escapement as far as I can tell and is about 4.5mm in height. If it helps the mainspring barrel is the size of the winding gear on the top and seems to be fully attached to it.
