I was recently shown the new Seiko Superior line with the 4R37 movement, and I was really excited at the prospect of essentially having a Seiko5 GMT. It looks awesome, right?
Oh, but wait. That's not a GMT hand. It's just a 24 hour dial, slaved to the hour hand. All it really tells you is whether the time shown is AM or PM. Here's the same "feature" on my MTG-1000:
This one has a little bit of value because when I'm setting the alarm or have it in world time mode, I'm actually interested in whether the time it's displaying which is not right now is AM or PM.
Citizen has the 24 hour hand down to a science, and seem to put it on nearly everything. Citizen may be the quartz masters, and could have an awesome traveling watch right here:
Imagine how useful it could be, with the UTC face showing the time at home, and the stupid little 24 hour face showing the time at your next destination. In other modes, the 24 hour face could do the 24 hour thing. If I'm not mistaken in these models you can't even change the UTC face to show anything other than Greenwich Mean Time unless you want to lie to the watch about what time zone you're in and accept that for a portion of the day your date is going to be wrong. Please correct me if I'm wrong.
So anyway, back to Seiko, who truly have no excuse: WHY IS THAT SUBDIAL THERE? Is it at all conceivable that someone will ever look at that watch and say, "It's 4:43 on the 31st, but is it nearly five in the morning or nearly five in the afternoon? I've been abducted by aliens and I DON'T KNOW!!!!" I'll answer my own question. No, it isn't. This is not a watch for spelunkers or Alaskans/Siberians, so the subdial is purely decorative. Since the dial doesn't impart any useful information why not just put a slowly-rotating magic 8 ball at 12 o'clock? Or the world's slowest pinwheel? I don't understand this stupid watch and I like nearly everything about it, but that @#$%ing subdial sits there on an otherwise very attractive machine mocking me with the watch it could have been.
In conclusion, here's another Seiko with the 4R37 movement. It has that braindead subdial AND what you might think is a GMT hand, but alas, it's painted on. Why? Because go to hell, that's why. Why would Seiko essentially make a dual-bezeled, GMT Monster? They'd only sell it to @0%%^&* everybody, and what would be the point of that?
