Are you buying it for YOU, or are you buying it to impress someone else?
Stop and think about that. If no one every notices it, no one ever comments, no one ever realizes you own it, will you still think it was money well spent?
If so, go for it.
I own a couple of nice watches in that price range, and hope one day to have a couple that are far more costly than that. But I want them for ME, because I like having nice things that my hard work earned me. By my standards, if you are doing it for yourself, and you can do so while caring for all of your other responsibilities, more power to you.
