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.

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.

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.

      I looked at it like this, I've built a lot of stuff in my time, building structures and furniture,those are my creations and they will still be here way way after I'm gone. Traditional watchmakers felt the need to pass their knowledge on, ideas that they created . I assume with them as it is with me, leaving their mark on the earth, a way of being remembered. This creation of Mark's has brought thousands of people together to pass their knowledge around,  ideas that will continue to be used for lifetimes. Ideas that should continue to be procured. If for whatever reason the forum ceased to exist, not quite like Ranfft's, that didn't disappear but much less usable. Then that is sad, such a massive loss of communication between good people and a wealth of knowledge lost. There should be something in place for when that happens which could be next week, next year or in 10 years. Might not be a topical subject for a lot of folk or boardering on controversy, i did say i talk about stuff other people dont. But if you dont talk about it and something happens then you've lost it and you ain't gonna fix it .

      I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark

      That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much.
