My reply would have been different if this was the first time you were making such a statement. Actually, it was very different the first time.
This thread is the second in just a few days where you claim there is no such thing as 6497 with eta stamping. You did not asked any question, you made a statement, despite being told it's not true already once, and having that confirmed by another member.
So forgive me, but I find a little easy that you now act all offended.
I just don't like people spreading false information. This could especially be a problem if someone with such a movement wanted to sell his watch. It could misslead him in believing his movement is Swiss, or made with Swiss parts, and therefore misslead potential buyers.
This is not directed to you personnaly, I don't know you and doesn't have anything against you.
You've been around for a long time, and you said you consider yourself a 6497 afficionado, so I understand you're having a hard believing you missed something like that, but please understand as well that it's not really my concern.
I just told you what I saw and read. Either you take my word for it, or you're calling me a liar. No other option here I'm afraid.
That said, these threads are here, so you can sure find them, as well as you can find people to confirm.
