hello, I have an issue with a stem from a seiko 6106 rally diver, I have had the same issue with a 6139 and 6105 as well and ITs totally mind boggling. How could a stem which is made for the same exact watch not fit right in a different case for the same watch? for example i had a 6106 which is mint i fully restored it new factory crystal fully serviced movement all i needed was a stem and crown. I purchased a parts 6106 the exact same model! literally same model 6106-8100 (since no other crown from 6106 is the same as the rally diver version) when i put the stem and crown in the case it is really hard to pull the crown out, yet when i put it back into the old it case its perfect! I had this issue with a 6139 and a 6105 same situation same exact case and model. i cleaned the inside of the tube i greased the washer, i mean what the hell! can someone explain this twighlight zone phenomenon with seiko stems???

If it happens with a given case but not another, then the problem is with the crown / case matching, not the stem.

it can be a size issue, which you can measure, or an alignment issue, which you can identify placing a bit of colored paste and observe where it stays and where it clears by friction.

In both cases a touch with the lathe on the crown may be needed.

its def. an oem crown and both crowns and stems are exactly the same. the movement spacer is perfectly aligned. i never have this problem with any other brand besides seiko its almost as if each crown is manufactured along with their respective case and wont fit right in any other case.

Brand blaming aside, I think that if you go over the steps I've detailed above you should be able to identify the issue exactly.
Of course another way to determine crown / tube "size match" is to try the crown alone in each case, compare the friction you feel. And if isn't that, then is the alignment of the two..

i tried that, the crown fits fine in the one gets stuck in the other. there is no visible damage to the tubes for both case and crown. i believe the issue to be the outside of the case tube not the inside. i just dont get it. I dont have a lathe so i cant really do any modifying. i guess i will just have no choice but transfer the crystal and bezel to the other case. just sucks because i have to polish the other case and its not mint the like the case i wanted to use.

Interesting. Have you tried the crown and stem in the serviced watch outside the case? Is it still difficult to pull out?

stem and crown operate fine in the movement while outside the case. its an issue with with crown going into the case. it still operates as it should when all together but its really hard to pull the crown out to set the time. i actually need crown pliers to get out you cant even do it with your fingers. and again this is happened with a 6105 case and a 6139 case. i just dont get it

Seiko tubes have external threading, which should contact the crown only when you press and turn. So if you try the crown without its gasket and movt, does it slides free?

If so you could try a smaller o ring.

      I looked at it like this, I've built a lot of stuff in my time, building structures and furniture,those are my creations and they will still be here way way after I'm gone. Traditional watchmakers felt the need to pass their knowledge on, ideas that they created . I assume with them as it is with me, leaving their mark on the earth, a way of being remembered. This creation of Mark's has brought thousands of people together to pass their knowledge around,  ideas that will continue to be used for lifetimes. Ideas that should continue to be procured. If for whatever reason the forum ceased to exist, not quite like Ranfft's, that didn't disappear but much less usable. Then that is sad, such a massive loss of communication between good people and a wealth of knowledge lost. There should be something in place for when that happens which could be next week, next year or in 10 years. Might not be a topical subject for a lot of folk or boardering on controversy, i did say i talk about stuff other people dont. But if you dont talk about it and something happens then you've lost it and you ain't gonna fix it .

      I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark

      That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much.

      Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release.
