      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 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

    • If the mainspring unwinds back through the stem then the click may have failed. On these earlier longines the click spring is concealed under the barrel bridge.    Loose screw - most likely you loosened the bolt screw to far and it has fallen out. Remedy - remove dial to reveal bolt (aka setting lever and hold static while you reinsert the stew again). 
    • I am ordering some things, and thought I'd try again to get this guy back on the road. The Incabloc springs fell out, and I broke one trying to get it back in. I tried micing it, but what I'm getting doesn't line up with any of the springs I see on the Incabloc parts chart. I was hoping to back door it by seeing if I can figure out what setting the movement it's based on is supposed to have, but I can't figure out what the movement is. The only markings are a faint "+ -" on the balance cock, and a star on the rotor (pictured, but difficult to see) that was under a decorative plate. 
    • Agreed. But I don’t think a 4-jaw is something I happen to need for my watchmaking lathe. Vinn says “4 jaw is best” but not for my needs. I’m not drilling main plate holes or anything like that.... I can’t think when I would have benefited from one.    That said, I have used a 4-jaw a few times when making some tools on the larger clockmakers lathe. 
    • I believe the watch is made by the morath bros of Liverpool. The watch itself is unnamed and only has a number printed onto the movement. Not sure how hard it would be to source a new wheel or clutch.  It has a sub second hand. Thanks for all the thoughts, very interesting.    I hope it doesn't cost too much. Was a recent ebay purchase and the repeater mechanism already needed work.
    • Sorry so.you mean power is bad on just the basic movement. If so then you need to start breaking that down too.   Removing the balance and the pallet, winding up the watch , what is the winding down like, smooth and fast or does it need help to wind down?   Sent from my ONEPLUS A6003 using Tapatalk
