It's not that they had a plan, it's that people don't really find any use to pay so much for it and people who bought Apple watch are pretty much forcing themselves to wear it cos they paid so much.
I'm sure multiple apple stores available globally did help achieve that. The same goes for all their products, you just see they care.
Because it's only compatible with the millions of iPhones.
Sorry, my smart watch has Spotify music stored, and is round.
What this shows is Apple did not just launch a watch for the sake of launching a new product. It shows they had a plan, and they spent the last few years executing that plan. Good job by them on following through their plan, because they got lots of flack with the first version.
