Which adjustment are we talking about?

[nickelsilver]

If you're talking about the screw that has holes through the head and presses on the regulator, and it has gone missing, first give the watch a good shake over a large table back open movement side down. It's probably in there. In the pic it looks like the regulator is at the end of its spring tension, so it may have wiggled out in transit.

 

You might find a replacement in a donor watch, doubtful you'll find one at a supplier or screw assortments. In my boxes of 10s of thousands of screws I haven't seen one. I have made them though, and it's definitely trained watchmaker territory (whether amateur or pro). It's a long screw, fine thread, small diameter, and putting the holes in well is a challenge too!

Rate regulation. Most watch owners don't know the difference either. Also, it would help if in the future posts the OP title is about issue at hand.

You can show us the boxes if you want. Just not the rest of the lab please, there is a limit to what an average hobbyist can take.

Another item on my list. I like to make screws and related jokes.

The reason I asked was that?

The missing screw seems to still be in the picture that's what was puzzling me? Sizing and maybe there are some other adjustment that I wasn't aware of that is missing?

Per OP:

Sorry no photo of broken screw in watch yes i should have done but this is a picture of broken screw.

[JohnR725]

I assume the rest of the broken screw is still stuck in the rest of the part?

[gaspurge]

Yes that is correct thank you for looking i suppose buying off ebay is a chance you take. 

[JohnR725]

You have several options here one you can just remove the entire micro swan neck regulator part. Then you have a standard regulating arm like any other watch and you can still regulate your watch.

I can't tell if your screw is long enough if you could remove the broken part of the screw which can be a pain at times last one I did was rusted inside needed soaking in penetrating oil.  If you get the broken part off you can see if your screw has enough threading they might still be able to regulate. Otherwise you look on eBay people are selling these I doubt the Swan Part is going to fit as I doubt there is any form of standardization but if you're lucky maybe the screw will work.

It would be best to go to a professional in this case.
