Hello there
Good afternoon.  I'm interested in your watch. 
It works great and barely used. It comes with additional wristband
Yeah, it looks like it's in great shape, even comes with the case.  I can give you $100 for it. 
I would like to sell it for $185
$185 is a little high for me-- I can probably do $115, and I can even come pick it up to save you on shipping it. 
How about 125. I'm afraid I can't go lower than that
That's fair.  I'll take it.
