Sorry to be snarky but I really don't see why that new 1.7" screen is getting so much attention in the press (laziness, perhaps?). It's not like this is the first E-ink watch, or even the first with a curved screen.
That happened in 2005, actually. The first watch to use an E-ink screen was also the first to use a curved screen. The Seiko Spectrum, which is pictured at right, was announced in Japan over 8 years ago. (It cost $2,200, BTW.)
And that's not even the only watch with an E-ink screen or even the only watch with a curved E-ink screen. Phosphor has been making watches with curved E-ink screens for some time now. They even have a smartwatch; you may have seen its Kickstarter campaign.
Show me a watch that does something new and I'll ooh and aah over it. Show me a screen that does something new and I'll say nice things. E-ink hasn't done either today, so I don't see what the news story is.
