I'm a big fan of GMT watches, especially the type where the hour hand adjusts independently (like most Seikos, JLC and a few others).
My beef is with the GMT watches that have an adjustable GMT hand and the 24-hr scale on the rotating bezel. Unless you have another 24hr scale on the dial, in which case you have a useful 3-timezome display, I don't see the point. Why waste the rotating bezel on the 24-hr scale if you can use it to print minutes so that it can be used for measuring of time? Anyone else agrees?
