Hello guys, 

I have a mido commander using a eta 2834-2. When removing the stem, I think I've pressed the button a little to hard and it's totally disappeared. Not sure if it's broke or just moved somewhere inside the movement. 

The stem won't engage. Any advice on how this can be repaired without completely tearing down the watch?

Proper approach is to remove the day and date ring to gain good access to the set lever and set spring which keeps nearly all the keyless put, there will be a minute train bridge to remove or loosen as well. 

Take couple pictures as you go so you know where parts came from and to be put back to.

Hi  Follow Joe's advice , you have displaced the keyless work. When removing the stem , pull the stem out to the set position before releasing the stem. This keeps all the keyless work in place under tension and in line ready to receive the stem when replaced.

From your photo, I  think you have pressed the setting lever too deep and displaced it. 

Mark has a video on YouTube showing how to recover from this problem. This is a common problem with the 2834.

For future work on eta movements, if you examine the hole the release  botton is in, you notice the following; 

The oval hole the stem release button is in, bottoms at a recess in center of which the circular hole is and continues deeper,  so if you insert a screwdriver of the widest blade the larger diameter of oval allows, your blade will plunge only as deep as the recess which is all thats needed for a perfect stem release.

I hope you can understand my ingliski.  ?

      Tissot case back removal

      By Neverenoughwatches · Posted

      It's not really shown here , but the blade flips over, so it faces the other way. The knob and threaded case holder then pushes the caseback seam into the blade. Once the blade starts to penetrate into it, the lever and blade are lifted , which should hopefully pop the back off. A lot of fashion style cases have very tight seams and need a sharp blade to start separating them.  Don't buy the cheaper plastic versions of this tool, the posts with the pins through for blade holder break easily if the apply extra force to blade.

      You will still be looking for a balance complete I’m afraid, this is the balance staff, balance wheel and hairspring in one package. Hairspring and the balance wheel are matched in the factory. Whilst we can change a balance staff the hairspring and balance wheel stay together.   Tom

      The hairspring end has come adrift from the small terminal barrel.  I have tried to remove the taper pin to relocate it, but the task is beyond my skill set, eyes, hands and being in my 70s, probably beyond my life expectancy.  It is not too badly mangled on the end.  On the ebay offer, that really is a bit on the rich side.  I'll keep looking, maybe a good hairspring will turn up with a shot balance staff. As for time spent on knees.  I made up one of these from 3M magnetic tape and a piece of wood.  It works well for magnetic parts. Other things I have suffered with.  I found lubricants so very expensive that I bought some very small syringes and tiny needles.  I just decant a drop into my oiling pots when I start a movement and the remainder keeps really well in the syringes. Finally identifying the correct screw for the part led me to make up the board in the final pic.   Thanks for the info. Kind regards   Chris

      Yes that's the type @watchweasol is referring too but I don't like them as you don't get any feel to what's happening.

      Hi there Stoller,   Caliber is generally stamped under the balance or thereabouts.  Caliber can't neccessarily be identified by bridge layout. Regs
