SWIM, pulled out the winding stem, while holding down the release button to replace the crown gasket and now when I try to reinstall the winding stem, it seems to engage the gear train and rotates the hour/min hands, but does not wind the watch, nor does it now run.  None of these symptoms were present until the stem was removed.

Is something damaged, and/or is there an easy fix to correct this situation?

I can take/add images if needed.

TIA,

MjB

Something has probably moved in the keyless work . Usually is the setting lever that has jumped of the clutch wheel . you probably need to remove the hands and dial and maybe the date mechanism to fix that. Don't know how handy your are with tinker with watches. But sounds as it's a job for a watchmaker.

I have had this happen to some watches.

First try remove the stem. Then as you are reinserting it, rotate it a bit left to right to make sure it goes into the castle gear bit.

Then if it goes in all the way, give the release lever a few presses whilst gently wiggling (very gently) the crown stem in and out (just a hair, less than 0.1mm).

Then try and pull the stem out so as to set the time, then push it back in.

It should be back to normal.

If not you can either remove the dial and hands as mentioned, or alternatively remove the automatic winding assembly, then remove the mainspring barrel bridge and try and reseat the castle gear and other bits onto the setting lever. As I hate removing hands on expensive watches, I usually go this route.

Good luck!

Thanks to you that have responded.  I have not had a chance to work on it yet but am encouraged by the suggestions.  As for manodeoro's questions, based on the serial number, it is from 1982 and has a 1520 in it.

I always thought that on 1520 movements the stem was released by turning a screw ... not a pushing a release button

Correct. If the stem in effect has just been pulled out then there is the fault. Hopefully not to much damage !!!!

Would you post a larger view of your movement ?
With the stem out but close to its place ?
BTW ... your Air-King looks great !!!

Absolutely.

Seventh post, second picture. Just "north" of the stem centerline is a small recessed screw. That is the stem release screw.

I had one break one me on a 1570 and it is an absolute nightmare to change- you tear the movement down about 50% just to get to it...

If the stem just pulled out (since whatever you pressed did nothing to assist stem removal) you need a new stem.

The only way to be certain is the OP post more pics of the movement and the stem as they are now

Have you worked with watch mov.ts before, and do you have all the tools and lubricants needed? If not, you're taking a big risk starting out on such a valuable piece.

Topic moved as the question is not specific enough and there is no information to discuss technically.

Well, sure, but if the stem pulled out without loosening the screw, the stem is worn and needs to be replaced.

Or, the retaining plate screw (mentioned earlier) is broken as mine did...

But, for the cost of a stem, it is foolish economy to not replace it in my opinion.

If it was me/my watch, I'd be checking the crown and tube very carefully as well, and replacing if needed. Might as well at least replace the O-rings since it has to come apart anyway.

Hi all,

I appreciate all the insight you are bringing to my situation.  Here are some additional images, post auto removal.  I do have replacement o rings so I aim to add some value.  Let me know what you see and thanks!

    • 1. I think the pivots look pretty good and I wouldn't worry about wear. 2. Yes, I think the hole jewels should come out for cleaning, complete with their spring setting. I don't have experience with Rolex but I've seen this spring type setting in another movement. They may be stuck in with old dried oil. 3. Yes, I think the overcoil is out of shape.
    • Yes, I'm looking at this option. I have a good friend from childhood who happens to be a goldsmith, and he would certainly be able to tackle the second hole to my specifications. I usually avoid this path because, since he deals with gold pieces, every time he stops to help me with "frugal" parts, he is objectively losing money. I agree with you. Even though I couldn't justify paying this much for the set (they only sell the whole set or the sole case tube), I understand the price tag. The trouble with this particular stem set is that the most common use case for it is the Technos Skydiver, a watch whose price certainly justifies 220 USD for a brand-new stem set.   I have messaged them only on the surface, without specifying my needs. They already stated that they don't sell the single female part, only the full set. What I still don't get is the need for a second hole. Is it supposed to be some sort of regulation, meaning that I can fit the head of the male part in any of the two holes to adjust the pressure of the spring? Does this mean that a single-hole female part has a chance to work with my setup? I'll later test this hypothesis while continuing the assembly of the movement. Some photos are attached. Can you judge this bracelet? It was dirt cheap (4 USD), genuine leather, wife's choice. I have just realized my dial is upside down. lol
    • Hello from chilly Brazil! I just bought a couple of watches and this watch came with them. While perhaps not worth much I'd like to try to find out something about it. Googling comes up with with the name Gerald Genta, and I see from internet searches he's made some nice designs (perhaps an understatement)! Also some cartoon designs but I can't find anything like this anywhere, so most likely not his!  Googling Royama I see that some famous people liked his watches and also the Royama watches. Two questions; 1. Can anybody tell me anything about this watch and its background? 2. How to get the base off to let down the main spring which is fully wound. I gently tried prying it but nothing, I see there is a button but have no idea if it is functional for removing the back or anything else. Screwed back maybe? I really don't want to break the back or the watch with too much pressure and haven't looked up the properties of Grilamid!   Probably not much of a watch but it peaked my curiosity and I hope somebody might be able to help? The auctioneer sold it as a psychedelic acrylic 1960/70 Royama watch overwound! All the best...Jules
