This is the latest project on the bench, a 1966 6206-8001 I bought it in the hope of harvesting a good keyless works set for the first of my 62mas's that I restored about 18 months ago. The case was destroyed (it had actually split) but the insides seemed reasonable and the movement gave up the parts I needed. The dial and hands were in excellent shape - especially considering the state of the case, so I made a mental note to keep my eyes open for another 6206-8001 with the hope of making a complete watch out of the two.

Anyway over the intervening months I collected a few more 6206 movements as I gradually restored the rest of my 62mas's, but never found a complete 8001 variant with a good case. A couple of months or so ago when Stefan burst onto eBay with his cornucopia of NOS parts I noticed he had a NOS 6206-8001 case for sale, from the very year of my original, 1966. I bought it and it took it's place in the queue of 'works pending'.

Today it has reached the top of the queue and I have made a start on it. It has the case (which included the crystal, gaskets, crown, movement ring, springbars etc) from Stefan, a movement from Ramon, and my original dial and handset which started the whole thing off. The movement was filthy but surprisingly ran when wound so that has been stripped and all the parts put through a jar of horozone degreaser placed in my ultrasound bath. I don't normally do all the parts with horozone but the movement really was disgusting!

This is the state of affairs now, all ready for the jewels caps to be lubed and refitted (a job I detest!) and the rest to be lubed and assembled. It will have to stay like this now as I have to go out in an hour but hopefully it should be finished over the next couple of days.







It helps to have a few spares, I still get the occasional part ping into oblivion - I must improve my technique!



The bench:



Apologies for the rubbish pictures, but I'll post some finished ones when it's done.

envious of your work bench! :clap:
Fixed it for you, Time.

At least that's how I feel. ;)

love your work bench! :clap:

:iagree: I would never be able to show a picture of mine for fear of being correctly recognized as the absolute amateur that I am....

Well I rebuilt the movement last night when I got back home and I'm pleased to say I'm finally getting the knack of correctly lubricating those diashock jewel end caps and refitting them and the retaining springs! Everything went beautifully and it was running strong on the timegrapher with a healthy amplitude and tiny beat rate error.

I left the refitting of the movement into the case until this morning and disaster struck! It turns out that the dial is to big for the case, even though the dial and case reference is identical! Just goes to show the title of this thread was apt. :-[

I have another 6206-8001 that I renovated last year so I took that out of it's case and measured it against the silver one - the silver dial is 0.75mm larger in diameter!



What I have decided to do is put the cream dialed movement into the NOS case, as although there is nothing wrong with the old case apart from the fact it's a little worn I have to use that beautiful NOS one! Here's a few pictures of the finished product:







Now I've got to keep my eyes peeled for either a larger 6206-8001 case or a smaller 6206-8001 dial. Does the madness ever end?!! :)

Looks fantastic, nice job!!


Are you going to turn down the other dial, looks like you have room to be able to do that. Just curious, the cream dial looks awesome..

I did consider doing just that AJ, but when I measured the position of the indices they were also .75mm greater in diameter which meant that even with the dial turned down the indices wouldn't clear the step in the case that the dial rests against. I'll just have to keep my eyes peeled I think! :)

Great work Duncan!

The dial incompatibility issue really puzzles me, however.
If part with the same part code are not compatible, then what is the sense of a parts coding system?

Is there any chance that the large -8001TAD dial is refinished?
Is the stamp on the back of the dial still legible?

Best,
Hermann

It puzzled me too Hermann! The damaged case the dial came out of had a 6206-8001 caseback, but the case does look slightly larger. With some more investigation I've had a look through my spares and I can see that there was originally an adapter that fitted between the dial and the movement that allowed the movement ring from the larger case to accommodate the standard sized 6206 movement. It is screwed to the movement with 3 screws and as I have some spare movements with the same tapped holes present, this leads me to believe that everything is as it should have been when it left the factory.
The dial most definitely hasn't been refinished, it has a brushed circular effect that would be very difficult for a refinisher to recreate. Also the dial font is spot on and the indicies look as though they have never been removed. It's another of the vagaries of vintage Seiko watches Hermann, just when you think you've seen it all something different comes along!
