So, I'd take it easy, and let someone else address that.

See this link http://fejack.net/misc/gmt24/gmt24.htm

The Omega Seamaster GMT has 3 crown positions. Position 1 (just unscrewed) is for manual winding. Position 2 (pulled out one notch) is for setting the Regular Hour Hand. Position 3 (center position) is for setting the Red GMT Hand, the minute hand, and hacking the second hand.

The setting procedure goes as follows: Unscrew the crown. From a dead stop, give the crown 40 - 50 winds. In position 3 (pulled out fully), set the Red GMT Hour Hand, the Minute Hand, and Hack the Second Hand. Then, push the crown into position 2 (center position) and set the regular Hour Hand. By turning the hour hand around the Dial two full revolutions, the Date will advance. This is how you set the date, and it will work forward or backward. Once the time is set, make sure you screw the crown in fully.

The way I use the GMT: I usually have the Red GMT hand set to home time. The Red GMT hand is on a 24 hour cycle rather than a 12 hour cycle. The bezel is used for reading the GMT hand. When I travel and change time zones, I only reset the regular Hour Hand from position 2 (center position). This keeps the Red GMT hand reading my home time, and does not disturb the minutes or seconds. This same type of feature is available on many of the Omega Quartz movements.

To read an additional time zone, I rotate the bezel. So I know my time zone (Pacific) is -8 hours of Greenwich Mean Time (Greenwich, England), I set the bezel to 8 and read the Red GMT hand to the bezel.
