How to remove stem on Certina 29-252 Quartz

[Chopin]

Could someone tell me how I can remove the stem from such a watch ? I believe it's a rebrand of an ESA 9181.

I can see a fairly large screw in the stem area but I'm not sure if it's that one. There is a two-sided arrow near it as well.

Also, I should pull the crown all the way out before attempting to unscrew anything, right ?

Since your image is hosted at an outside service, I can't magnify the image, at least without signing up for their service or something.

Based on what I might be seeing, I'd press that copper colored spot, to the right and down from the crown maybe 8mm or so, and pull on the crown. However, if pressing the spot doesn't look for feel springy, I wouldn't force it. I just can't see it clearly enough. Good luck.

Here's a better image I hope. I can't see anything that should/could be pressed.

I'd still be going for the area I referred to. Sharpened pegwood works pretty well usually. That minimizes chances of slip damage.

If not, is that a hole almost directly above where the arrow is? If so, that might be the release. I've seen little metal spring-tabs in such recesses.

The part that you pointed the arrow at actually moves as you pull or push the crown so that's why I fear it might not be what needs to be pushed. Will try to check tomorrow.

I did think of that hole but I can't see much inside...

That's exactly the indication of that being the setting lever you need to push.

It's partly made out of plastic... Will further check tomorrow.

I have found that many ETA calibres have no release button but the screw beside the stem needs to be loosened a turn or so...but just until the stem is released. I suggest being very careful of pushing on anything if there's no embossed arrow pointing at it...the electronic circuits are easy to damage.

The thing is that I loosened that screw near the stem (quite a bit) and it didn't work but I might have to retry.

Alright, I figured it out. It's this hole here where the tab that needs to be pushed is located.

The hole made the most sense once I realized that the other spot was a bit far from where most releases/detents would be. Good luck with the job.
