Radio-calibrated movements aren't all that new. Seiko has used them for years. However, this watch is much slimmer, about 3.5 mm, and can catch time calibration data from three different sites around the globe. As far as I know, the radio calibrated watches available here only work here or Japan, but I'll confirm that in a moment.
Why should you care? Well, you'll never have to set your Hello Kitty Atomic GPS watch ever again if it's using this movement. However, the use of the word Revolutionary in the Epson release—"Epson Develops Revolutionary Radio-Controlled Watch Movement"—gets them haterage points from the anti-PR claptrap contingent, mainly me.
