I didn't use the word "cheap". That's a word you've inserted. So you've added straw-man to ad hominem and general rudeness.
And you've already conceded that there are plasticky-looking parts (the phrase I did use) inside Rolexes - Teflon is a plastic. By doing so, you further conceded (although perhaps you don't realise it) that in fact I'm well-informed.
You really are tiresome. Have a look at the other comments about you on the last two pages. Everybody now is starting to wish you'd just go away.
Please speak for yourself. I don't personally know mafoofan from Adam, but he knows watches, and his input in this thread is very welcome.
