The problem with your second movement sounds like the spring on the keyless works cover isn't fully engaged against the yoke, see HERE for a fuller explanation.
Good point,"little white lies" anyone. Also being advertised as "Swiss" HERE.
My first thought when I saw this was that it looked Swiss but the consensus amongst those who have expressed opinions in this thread suggests clone.
Thoughts anyone?
A lot of people sell clones as "Swiss" because that's what the dealer advertised the watch as having when they bought it. If you can post a hi res close up of the top of the balance assembly it will be easier to tell exactly what you got there.
The stamp under the balance will tell you what it's supposed to be 2824/2836. However, the lack of holes on the reversing wheels suggest this is probably a chinese clone, not a bad movement but not Swiss. A clearer close up of the balance cap assembly would help to make a definite id.
Not saying this is a fake, just a few subtle differences on the movement, if you could get a clear shot of the movement showing the balance it would be an easier tell.
Well I can see some small differences between the movements but I suppose that's possible as Oris uses both ETA and Sellita movements. Mine is an ETA 2836-2 do you know what's in this one?
Don't see the pictures you linked to and I think I'd like to see a more detailed image before commenting.
Edit to add:
just too late, now I see the pics
