Most people really dont care what kind of watch you are wearing, much less whether it is real or not.
If you are wearing a blinged out diamond loaded watch to a job at burger king, or anything like that, you are asking for someone to comment. OR LAUGH.
If you wear a watch that is appropriate or one you could honestly afford, then no one would look twice.
If you wear a watch that you or your wife likes, who cares what people think.
