Stem removal on a Swiss army watch

[mark1]

I have two of the same Swiss army watch. I need to replace the stem and crown's on each. I cannot find any info online, regarding where the stem release would be.

Can someone please help.

Thanks

At a guess, I'd say either press A or unscrew B and lift the brace, I'm sure that's what's locking it in.

 Well, It was sort of what you said, The post in the middle is what is actually holding the stem in. But the only way to get it to depress, is to move/remove the clip. Once I did that, I was able to depress the post in the middle, and the stem released. So, Now I've got the stem out, and trying to figure out which piece to buy to replace it. I noticed the numbers "1198" on the watch interior, And they seem to be numbers I see correlated to certain stems. Is that what I need? an 1198 stem? Here's an image to the stem I pulled out. Is there a name to this particular style of stem? Sorry for the newbie questions, I'm really good at due diligence and research, but this is like a stab in the dark finding info online for some reason.

I've actually got a digital micrometer coming tomorrow, so I can measure this thing, and the crown.

So, this is the chart I saw on Esslinger, that had the 1198 numbers correlating to the stem. Am I way off base here?

Ok, so what I’ve found, is that this is an AV SEMAG movement ISA 1198, and does appear to use the 401-1021 stem.

 

can anyone confirm these findings?

Hi Mark  after some research it looks as though you are right as listed.

Sorry I didn't reply earlier, have just checked back this morning on the forum.

I wouldn't have been much help unfortunately, stems are a pain unless a common model of watch or movement.

Hopefully that's the right one and glad you got it removed.

Thank you "Watchweasol" and "m1ks", I appreciate the help. Parts are ordered. Hopeful that I am going to be good with the crown I ordered, as the diameter of the original was 4.3mm and I couldn't find any that exact size, so I ordered a 4.5mm one. the space for it was 4.9mm so I think I'll be OK. I will update all this once the repair is done, in case anyone is ever searching for this info, like I was.
