$AAPL's CEO was quick this week to defend the company's  I Watch sales.

“Our data shows that Apple Watch is doing great and looks to be one of the most popular holiday gifts this year," Cook said. "Sales growth is off the charts. In fact, during the first week of holiday shopping, our sell-through of Apple Watch was greater than any week in the product’s history. And as we expected, we’re on track for the best quarter ever for Apple Watch."
