According to this [0] Apple made 93 b over the past four quarters. The Apple watch is bigger than the entire Swiss watch industry [1] but still a minor part of Apple.

My point being that they’d have to sell a hell of a lot of services to outpace the iPhone, and those services are mostly popular because they integrate into the iPhone. And people want the new shiny ones.
