The Apple Watch is so far the fastest selling Apple product ever (fact), and it's going to be a blockbuster this coming holiday season.
How are you calculating that its the fastest selling Apple product ever?
E.g. in its first three quarters, the iPad sold 3.3, 4.2 and 7.3 million units.
IIRC, estimates for the Watch are around 2.7 to 3.6 million for its first quarter, and 3.9 million for its second, which puts it possibly slightly ahead and then slightly behind the iPad so far.

Oh. Are you perhaps repeating Cook's comment months back that the Watch's initial SELL THROUGH was higher than the iPad's?
That's just clever handwaving. Obviously the sell through to end users was higher for the Watch... not only because there was a much larger user base five years later, but because almost all of its initial sales were online to end users, whereas almost all of the iPad initial sales were to retailers (i.e. NOT "sell through").
Cook is well known for coming up with juicy tidbits like that during quarterly calls, where you have to listen closely to understand what he's actually saying. He knows full well that most reporters will drop half the comment and change the meaning. And sure enough, most reporters failed to include the "sell through" part or even think about what it meant.
