The watch featured a 32-millimetre (1.26 in) 144 × 168 pixel black and white memory LCD using an ultra low-power “transflective LCD”

The problem is that e-paper is a category of displays, and some companies label reflective LCDs as “e-paper”. Which is subjective (and I personally heavily disagree with that categorization, cause then LCD clocks and Gameboys have “e-paper” displays, too).

But in the comment I responded to it was said Pebble has “eink” display, which is categorically wrong, as that is a very specific proprietary technology, which is e-paper in traditional sense, like the ones in Kindles.
