Apple Watch is on a steeper trajectory than iPhone and iPad were.

>The Apple Watch has sold more units in the first nine weeks following its launch than either the iPhone or iPad did at the same point after their respective releases, Apple CFO Luca Maestri said on Tuesday. [1]

I believe thats mostly due to the combination of the hype surrounding the release of Apple's latest product line, and the fact that Apple has A LOT more potential customers paying attention to it than it did when it launched the iPad and definitely when it launched the iPhone.

Also Apple launched the iWatch in more countries than the iPhone and iPad, including China (their second biggest market). The iWatch demand and initial sales will be more front loaded than the iPhone and iPad

Also: the aWatch is cheaper than either the iPhone or the iPad was at launch (both cost $500 for the cheapest model, as opposed to $350 for the watch).
