The Apple Watch has 290/302 dpi which barely qualifies as high DPI. 290 is just below their own stated Retina threshold. Anyway, I hope they'll have a better sc

  Both screens have equal pixel densities and have 326 ppi (the larger screen has consequently more pixels). Where do you get your 290/302 ppi from? That’s just wrong. The display of the 38 mm watch (38 mm refers to the height of the whole watch body, including bezel – it’s ill-fitted for calculating pixel density) is 21.22 mm wide (0.8354 inches) and has 272 horizontal pixels. That’s 325.6 ppi. The display of the 42 mm watch is 24.34 mm wide (0.9583 inches) and has 312 horizontal pixels. That’s also 325.6 ppi. That’s the same pixel density as the iPhone (excluding the 6+ with a higher pixel density and older non-retina iPhones). Now you can argue about whether typical viewing distances for watches are closer or farther than for phones (whether or not a screen is “Retina” is always a function of the typical viewing distance and the pixel density, never pixel density alone and there is no single device independent pixel density that is “Retina”), though I actually think on balance they are probably slightly farther or the same.

    You're correct, someone screwed up in Wikipedia (the Retina display page) and I didn't bother to check the math.
