From what I've seen, PenTile appears to be mainly a cost-reduction trick that works well for displaying photographs and other images with gradual variations, but looks horrible for text and sharp, straight lines. A similar pattern has been used in cheap cameras for many years:

The Apple Watch pixels are not in the traditional stripe pattern, but there's still 3 distinct subpixels for each pixel and they're arranged in a square pattern. The unequal subpixel sizes are due to OLED brightness fade; the blues wear out the fastest, while the reds last the longest:

Does it vary the intensity as it ages? Otherwise, it seems like the displays would start out way too blue before eventually becoming "accurate". (And then going on to become too red, of course.)

Edit: Oh, or maybe having a bigger blue subpixel means they can run the blues with less intensity, thus extending their life?

Don't the latest Samsung phones (S6) still use pentile? I don't think those look bad at all.

They look fine now because the resolution of the screen is so high. Previously you could definitely notice issues with it.
