Seiko 6139-6010 aka "Bruce Lee"

Recommended Posts

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

Wide range of restorative attempts and I say good job, too many to master all though. 

I buy more selectively focusing on the work you enjoy tirelessly. 

Cute balance cock stand tell about the artistic person in you.

All the best.

Hi, this is only a discussion forum. Members are not allowed to offers goods or services for sales.
You will have to locate a reputable repairer local to you. You can also check a Seiko forum like SCWF for recommendations.

The OP's friend had a go to the piece already, and if I guess correctly it now suffers of low amplitude, a typical Seiko issue, not easy to correct and for which a new mainspring is just a part of the cure.

I think that for a beginner to attack a desirable chronograph of EUR 400 starting value would a big mistake with slim chances of  success. Much better to give it to a professional, pay a fair price, and enjoy the watch in its best conditions and in conditions to be passed down or resold.

@ZakIf you need help with our watch, please introduce yourself first in the appropriate section. After that, please start a new thread.

@jackie01Sorry for going off-topic, and well done with the restoration. Looking forward to reading what you do next.

Excellent work, I've got one of these coming from eBay this week. I will eventually look to strip it, but I've got a bit more practicing to do first. Really useful to see what awaits however. :thumbsu:

      Hi All
      Any ideas how I can improve the look of this calendar ring?
      The staining seems to have got underneath the lacquer.  I've not tried anything yet as I'm a little hesitant at using any liquid on it for fear of damaging the lacquer further.  i'm still learning...
      Many thanks

      I've tried to service a tiny Seiko 2601 Automatic movement very small for me (18 mm)
      So I finished  yesterday all was ok I've rewinded and I was happy because the balance started I've not checked amplitude or precision (for me just ticking it's already something)
      Today I check and the watch have stopped and do not restart even when I rewind manually. 
      Now when I put the main spring back in the barrel I've broken the end part at the opposite side of the pinion it was like a V because I don't have a main  spring rewinder so I make it manually (Shame on me).
      So I suspect that the main spring is not clamped in the barrel and it's just spinning inside without giving any power to the movement.
      The question is what method can I use to check my assumption. Not forget It's an automatic movement.

      Good day all,
      I'm a recent 30 year retiree and elected to start cleaning some of my older watches that ended up in a box wrapped in a towel.  One in particular, a gift from my grandfather, began working with a new battery but the crystal appears foggy.
      I would appreciate specific instructions for removing the stem/ crown and cleaning the crystal from an 1980 Seiko with the 6030A movement.
      Thank you in advance.

      I recently purchased what I call a “Franken-watch” Seiko from a seller on eBay from India. As I’m sure many of you know by now there are hundreds of listings (see screenshot below) for cheap Seiko watches with weird dials, most likely repainted. They aren’t fully “fake” as most of them come with genuine Seiko movements. My Retro Watches has a good video where he looks at a watch he bought from a dealer similar to this if you’re curious, see link below.
      Anyways I thought one of these cheap weird watches would be a fun one to play around with as my first project, and I paid $20CAD for mine which I thought to be good especially if the movement inside was genuine Seiko. First problem I noticed was the bracelet (which was cheap and terrible) was held in by shoulder-less spring bars which would be fine if the lugs had holes but they do not so I had to saw the bracelet off so I could put another one on (see wreckage below). There’s more but I won’t bore you too much..
      The watch came with a Seiko 6349A (23J) movement which is a variation of the Seiko 6309 (17J) movement. The movement was held into the case only by the crown (see pictures below) and didn’t have a movement ring. As I understand this is bad because the movement isn’t securely held in the case by anything. I’ve tried to find one on eBay but I’ve had no luck, and I can’t find anywhere that has the ring size so I can’t try and find an aftermarket one. 
      Does anyone know where I can get one of these movement holder rings? Is it even possible to get one off of CousinsUK or Esslinger or somewhere? Do any of you have one I could buy? I am very stuck and any help is greatly appreciated!

      Can someone please explain to me how on earth do i unwind this Seiko 5126A movement prior to reassembly? (Picture attached).
      No manual winding as far as I could find and the winding screw on top of the bridge is not counterturning automatically when I push back the click and basically nothing happens. I can unscrew it but this just releases the screw.
      I'll mention that I did experimented with this movement (it's my watch) and first time accidently removed the bridge with power still left. No visible harm was found and after reassembly (hopefully a proper one) everything seemed in order (except for the oiling and cleaning which I haven't yet performed and is due now).

    • Thanks all for your input.  I'm looking for how to test the coil, crystal,motor, and any other electronic parts.  
    • Same symptoms can develope due to moisture damage to electronics. This caliber might be obsolete, in case exploded view of the movement is not available and you decide to attack this yourself, take pictures at every stage of disassembly.  Good luck  
    • At the very bottom of the page in the link on the right side.  The last one.  On my screen it shows up as (RWA) A-29418-5 Rheostat, 800 ohm, 50 watt, 0.25 amp. Type R-50. 2-1/4" diameter body, 1-3/8" behind panel depth. 1/4" diameter x 1/2" long round shaft. Made by Memcor. NSN: 5905-01-013-4370. Dave said this one is close enough it should work.  One thing I noticed is the wattage.  it's 50 watt and the machines are rated at 60.  Also the amperage, seems low.  Can't remember what the machine runs at.
    • Well, I inherited my Dad's watch bench and have since bought two more. Working theory is that you cannot have too many watch benches.
