Seiko 7015-8000 restoration project


Recommended Posts

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.

Great attention to detail, the crystal came up amazingly well, as did the case, and that orange second hand looks factory. Excellent.

I was looking for the best paint color, the closest to the original one
Few words about performance which is achieve - amplitude circa 220-230 degrees, but I still have to do some adjustment cause the beat error is something about 0,8-1,0ms. I suspect that I must align hairspring at the collet.

That is absolutely fine and needs not further attention. I have seen brand new Seiko being shipped with as much B.E. and keep good time. Just wear it at least one week and do a final regulation if needed.

    • John I have seen the information of the internet regarding Arnex https://theoldtimey.com/arnex-pocket-watch/#Arnex Watch Value https://adelstein-workshop.com/arnex-watches/ Very interesting. oldttimey estimates a value of £75, if everything is original.  Can't find an original movement as a donor. Silly prices wanted for a full donor watch. I can get an st3600 6497 for £40. Owner is more concerned wit the 'look'.  What I am pleased about is that by learning from others, I have been able to rebuild to the point where I was able to understand why it would not work. I know that I am not very good with describing my work. But achieving the outcome has been good for my ego. Know what the problems were. Know my limitations. Chuffed.
    • Out of curiosity I don't suppose you want to share the prices? Yes it would be cheaper to get a Chinese clone but this is not a Chinese clone this is a Swiss 6498 and the last time I looked brand-new movements are extremely expensive. I see the answer has materialized before I Finished this I'm still curious genuine Swiss because as I said the last time I looked they were rather expensive. Although taken a quick look at eBay it looks I can get a movement For approximately $130. Otherwise I'm seeing silly prices starting at $400. This is the unfortunate problem of anything that is well watch repair Somebody in there before you that didn't grasp what they were doing and now you have to pick up the pieces. It seems be unfortunately the world of the watch the more pieces of the stuff you have to deal with. I suppose it's a miracle that in the watch runs at all. On the other hand the number of amateur parts destroyers of watches versus the quality of watches well that's probably a good thing that there only a tiny percentage of
    • New movement. I have told him that it will be an old watch but a new movement. He is happy with that. 
    • I think you misunderstand what I was getting at I was quoting you. You're the one who found the color Rolex manual and that's definitely worthy of an acknowledgment.   So you don't need to apologize for anything I wasn't offended. As I said I was quoting you because you brought something exciting I color Rolex manual a PDF color manual. I just wish you'd remember where it came from and whether they had any other color or any other Rolex manual's.
    • Hi all,  I am currently working on a tissot 2481 (equal to an omega 1481) and have tried to replace the mainspring, I ordered the correct spring from cousins but the centre spiral wasn’t tight enough for the arbour, the only option I had (with limited skills and knowledge) was to bend the spring to suit, after several attempts to get the correct size it led to the spring snapping is there an alternative mainspring suggestion as it seems it is the cousins Swiss one I’m having the issue with or does anyone know where I can source a mainspring barrel complete? thank you in advance Sam
