I have a Seiko age of descovey 6M13 the stem broke in half with the stem still in the movement. I have tried the typical release button but it won't slide out on its own. Is there any tips or tricks to removing it.

 

Any help is appreciated.

Is there anything left of the thread inside the movement? 

A stem extension in the right size to thread on the remaining thread could work. Or you will have to take the movement out of the case? Gentle knock at the same time as you press the release button?

      What are these Seitz B-Jewels?

      I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!

      Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.

      So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.

      Well I’ve never seen the make before and cannot find any info, I haven’t got it just yet it’s been left to me among a 1970’s sea master and a mid size yeoman. But if anyone has any information on this one please feel free to enlighten me, many thanks
