They seem like budget versions of the Grand Seikos, which is something Seiko apparently likes to do to undercut anyone looking to pay $6000+ for a GS. No mention of the GMT mechanism though, whether it's a slave 24hr hand, independently set, or jump-hour.
For me, I'd rather go with either of the Swatch Group's low-end offerings; the Mido Ocean Star GMT or Certina DS Action GMT models both come in a couple hundred dollars less than this Seiko and feature a jump-hour mechanism for "true" GMT capability.
