5-7 day battery life and always-on, e-paper-like color screen. This enables you to use Pebble as an actual watch, or in general as an information radiator - you don't have to interact with it in any way to see the data you need; you just have to look at it. They had these features (sans color) before Apple Watch / Android Wear even existed!
What personally made me buy Pebble over Android Wear / Apple Watch was not point-by-point spec comparison though, but the apparent philosophy of the company since day one. They went with practical (always on e-paper screen instead of touch) and hackable (Pebble is programmed in C, no stacks of Java bloat, no licenses to buy). From the beginning, they were giving off the utilitarian vibe, as opposed to the later Apple's strategy of building an expensive toy. It's a difference of mindsets.
Or at least it was, given that Pebble seems slowly going towards the mainstream.
