The iPhone was successful because everyone needs a phone, and it was a quantum leap in phone functionality (to the point where the actual phone function was secondary). And it was beautiful, so even if you only used it as a phone, it still made a fashion statement compared to the typical candybar phone or utilitarian Blackberry. No one needs to carry a watch, so the Apple Watch has a much smaller potential market to begin with. It really needed to succeed as fashion (since that's a major reason anyone wears a watch these days), and it simply hasn't. The original iPhone looked like the future. The Apple Watch looks like a slightly sleeker version of a Dick Tracy wrist radio. The Apple Watch (or whatever wearable form it evolves into) will be truly successful only when it can replace the iPhone entirely.
