Most of the current crop of smartwatches trying to be lightweight smartphones are all turkeys and have fizzled. Kind of like the early tablets that tried to be computers when the actual product demands a 8-10 hour (work/school day) battery life. Battery life is even more critical with a watch which needs to last at least 16 hours, hopefully quite a bit longer, and you probably want it to keep telling time even if the main battery goes out unless that battery lasts the better part of a week. So the correct way to design a smartwatch is to, as Apple did with the ipad, figure out the device size and computing capabilities backwards from the battery life and then go to market when you're happy with what's possible. The Pebble, to it's credit, has a Cortex-M microcontroller instead of a smartphone SoC and get's up to a week of battery life.
