$3/4 Million for a Watch

I stopped wearing a watch after I bought my iPhone. Why have a watch when I have a world clock at the touch of my fingers, plus an alarm clock, a stop watch, and a timer, all in my phone. BillionairesLife.com has found a watch for sale for three quarters of a million dollars. I hadn't realized that high end watches were so expensive, selling for the price of a California house, or for three or four Midwestern houses.
