Correct use of "... of yours"

Hello,

I'm writing in regarding the correct use of "... of yours".

For example, when should I say "I like your watch" or "I like this watch of yours"?

I looked on the internet and in my English grammar books but to no avail.

Thanks in advance for your help.

Regards,

Florian

 "Yours" means "belonging to you" and thus both of the examples you quote is correct, although the latter "this watch of yours" is more colloquial and would be regarded by some as poor English, even though it is widely used. The word may also be used in letter as in "Yours faithfully". It should never be written "your's" !! Also look our for the difference between "your" and "you're" - incorrect use of these words is a very common event in English. Remember "your" means "belonging to you" whereas "you're" means "you are".
