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 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.
Well, this is my first effort of a watch repair. I have been fascinated with watches, clocks and all kinds of mechanical things since a young age. I decided at this time that working on watches would be a great hobby/interest to take up in my later years. I have already spent some time learning to refurbish and repair fishing reels in the last few years. So here is my first repair attempt.
Interest in tinkering watches started when I dropped my Seiko SKX009KD diver to the tile floor in the bathroom. Was not too good an idea to put a watch on there with a towel thrown over it, pulled the towel and down comes the watch, face down on the tile floor. Needless to say, I picked it up and took a look, nothing seen. Then I shake it and hear a rattle. Not too good!
So I did some research on the 7S26C movements. Read a lot of information and watched a lot of videos. Thanks to all that makes this information available. So I purchased a cheap watch tool kit from Amazon. I had other watches that needed batteries and some strap work anyway. I knew the kit would not be 'pro' grade, but it was a nice kit with all the basic tools needed.
Back to the rattle, I figured the Oscillating Weight (OW) had become separated from the bearing. So I used the case back wrench in the kit and opened the back, and sure enough that was the problem. I looked on-line for a replacement OW but could not find any except one on Ebay for $35! So I decided, what the heck, I'll try to repair this one. So, here is what I did being a little mechanically inclined but never at this small a scale, I performed the following:
1) remove case back.
2) examine the OW, it was dislodged/loose from the bearing.
3) remove center OW bearing from center post.
4) place OW on a small anvil, then use a small pin punch from the kit as to carefully work the metal around the OW's hole as to make the bearing hole smaller.
6) After enough working with the punch, I took a smooth round stone and gently kept working the ID of the OW hole until it just would friction fit to the surface of the OW bearing.
7) carefully press fit the bearing into the OW, I knew too much pressure would ruin the small bearing races and ball bearings.
8) finalized fitting of the bearing to the OW by applying a very small amount of red Locktite thread locker using the end of a pin as an 'oiler'.
9) I then let the OW set for a day to cure the Locktite
10) install OW per alignment instructions in the 7S26C technical guide. At this time I also wound the mainspring up 8 turns to check the power, it ran for about 40 hours.
11) did not have any watch oil, so I used a very small amount of some 10W synthetic engine oil using a small pin as the oiler to lubricate the OW bearing ONLY.
It appears to be a successful repair for now, watch been running great and keeping good time for about 2 months. I'm sure something else might have gotten damaged during the fall, especially the balance assembly, but then again the watch is working fine for now. I might use this particular watch to dive deeper into the 7S26 movement at a later time. Kind of happy for now. Got 2 other watches running with new batteries, fitted some straps and having fun with my new hobby. Look forward to learning some more. Now to find a 'bag o watches at a flea market and get busy. I know I'm going to need more and quality tools down the road, that's OK with me.
I'm Newbie for watch repair. I have watch Seiko presmatic 1968 cal.5106-9000. the movement is to old and i want to replace the movement with other cheap movement.
what type of movement that i can use it to replace the movement. I need your advice please.
oh ya if it possible replacement with china movement, what type i can use tp replace it ?
Thank You so Much
