It strikes me as odd that we hear leaks that imply Apple struggled to finish the watch on time. That they were worried about battery life. That the launch could be late. This doesn't quite tally with the company which supposedly has nearly two year's worth of products waiting in the wings. It's like the leaks are there so we believe this is cutting edge. I think there is an Apple Watch inside Apple that works independently of iPhone. It might be as far away from release as 2017. It might still need tweaks, or fixes, and a little more development. Haven't Apple said "native" watch apps are coming later this year? Presumably, these won't need an iPhone near by, as they'll run directly on the Watch. With that in mind, it's not that big of a leap to assume that, within two generations, Apple will also add GPS and a micro-sim tray, and that Apple have a battery that will support these additions. What do you think? Edit: If they make it work independently, but works best with iPhone, then it will be like when iPods started working with Windows PCs, right? Android phone owners will be able to buy one.
