Most native english speakers, including myself, speak english poorly, at least with respect to the correct use of grammar. The answer
"....where my watch is?"is indeed the way it would be stated by many u.s. english speakers, as opposed to what would be more correctly stated but awkward sounding to most grammatically challenged americans than the more correct .."where is my watch?"
one shouldnt end a sentence with linking verb.."is." It would be more appropriate to say "does he know the location of my watch?" But saying that would SOUND as weird as "....where is my watch?"....both of which are more correct gramatically than the typically grammaticly lazy "does he know where my watch is?"
That would not be correct. This is an indirect question (ie a question introduced by something else. In this case, another question) and therefore the verb goes at the end (see http://www.bbc.co.uk/worldservice/learningenglish/flatmates/episode46/languagepoint.shtml).
You are right. In Italian, you do not change the sentence to make it a question. You just say the sentence with a question mark at the end.
"Lui sa." = He knows. "Lui sa?" = Does he know?
It's way easier than you think, don't confuse yourself :) Another example is:
"Tu mangi il cibo." =You eat the food. Ma, "Tu mangi il cibo?" is "Do you eat the food?"
I did read the other comments. I wasn't really satisfied with the answer you gave above, frankly. It seems to me that "Lui sa dov'è il mio orologio?" could be translated to "Does he know where my watch is?" or "He knows where my watch is?" just as easily, basically because in Italian, there doesn't seem to be a distinction made between these two questions where there is one in English. I was kind of hoping that someone would either have a more grammatically through explanation for why my answer is wrong, or confirm that I'm not crazy and there's nothing wrong with "He knows where my watch is?" because as I said before, it's a legitimate English question.
You know, putting a little smile after insulting my English isn't really going to make you seem less condescending. You are the only commenter who specifically said why you think "He knows where my watch is?" isn't a correct English question, and again, I'm not satisfied with your answer. It's true that it doesn't mean exactly the same thing as "Does he know where my watch is?", but if you translated "He knows where my watch is?" to Italian, you would still come up with "Lui sa dov'è il mio orologio?" It's perfectly legitimate to use a question to express surprise in English, and I imagine you can do it in Italian as well.
I'm sorry you felt insulted by my comment: I didn't mean to.
If you want to convey the surprise then you would add "Davvero" (or something similar) to the sentence to mark that it is not a "normal" indirect question. But then you would need to mark it somehow in the English version as well.
dove stai = 'where are you'. I think you mean dove sta.
Well, it is not wrong but stare is a tricky verb as it is mainly used by Southern dialects and from there 'abused' in Italian .
My advice: avoid it unless you're 100% sure it's needed (ex. stare per, stare -ndo, stare bene/male)
How would one know this were a question? She didn't say it in a particularly fashion that indicated a question and in real life that would surely be more obvious, but in this case, how would I have known it were a question? Would the construction of the sentence have been different had this not been a question?
In Italian, the only distinction between a normal sentence (stating a fact) and a question, is the question mark at the end (and the tone were it not a computer generated voice). So: Lui sa dov'è il mio orologio? = Does he know where my watch is? Lui sa dov'è il mio orologio. = He knows where my watch is.

I see so many people putting "Does he know where is my watch?" And "He knows where my watch is?" "He knows where my watch is?" Is really just a sentence but we tend to put a question mark at the end because when we say it, it sounds like a question. We fix this little conflict in our head by making it a question in writing too. But, its really not a question. And the first sentence is just awkwardly worded.
