Hello guys. This is my last project – Seiko 6139-6010 aka Bruce Lee. Watch is from ‘69and it is based on the 6139A movement. Nice shot for the 50th Seiko anniversary of first automatic chronograph development. So please see the pictures below from all restoration proces. It took me 3-4 evenings.
The watch came to me as non runner. Crystal was scratchy with many chips. Dial was dirty and dusty with signs of water damages. Hands lost their lume. Day calendar was loosen and didn’t work properly. Movement was complete but very dirty and dry – there weren’t any residues of old oil in the jewels. Somewhere were signs of water flood. I dissasembled movement and I gave it a bath in ultrasonic cleaner then i’ve assembled and oiled movement. Star disk od date wheel was repaird with small amouth of resin glue. Movement had tend to stop sometimes. Inspection showed that the tiny chip on the bottom pivot of the escape wheel. It was hard to see it. After replacment movement ran as a champ. I polished the hands cause there was rust and gave them new lume. Dial was cleaned. I didn’t touch the lume on the hours indexes. I was affraid to screw up it. I think now it is quite good despite the fact that the lume does not glow. Orginal crystal was polished but I decide that in the future I will replace it. Case and caseback got some polish works only with polishing paste, not too much cause I didn’t want to loose the sharpnes of orginal edges – as usual I did it. Bracelet was matted with abrasive wool. Everything was mix up and combined and there is the result.
After measurments on timegrapher and adjustment it is a nice timekeeper. An amplitude satisfy me as well. Now I am enjoy to wear it.
Please let me know what do you think of this restoration project and about my works on it. I appreciate your comment and your spend time. Cheers folks
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.
I'm a complete newbie and want to learn how to dismantle and re-build watches, specifically Seiko's.
Any suggestions on what movement to use as my first independent project to practice on and make loads of mistakes? Struggling to find recommendations on the different movements to use as a complete beginner and as my skills improve. Should i stick to only Seiko's or broaden my horizons?
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
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.
