Instructions for the GMT II
Let us label everything as follows:
* S---the second hand.
* M---the minute hand.
* H---the twelve-hour hand (the typical "hour" hand).
* T---the (red) twenty-four-hour hand.
* B---the bezel.
The winding stem has four positions.
* Position 0: Crown screwed down (default position).
* Position 1: Crown unscrewed and just free of the screw threads (for hand-winding).
* Position 2: Crown pulled to first notch (makes the H hand move by +/- 1 hour; this does not impact S, M or B.)
* Position 3: Crown pulled to second notch (the watch stops, and you can advance M and T hands as you see fit).
How to set B
You don't have to touch the stem to play with the bezel. If your local time zone is negative (you're west of Greenwich), rotate B clockwise by the correct number of hours. If your local time zone is positive (you're east of Greenwich), rotate B counterclockwise by the correct number of hours. If done correctly, T, when read against B, shows the twenty-four hour time in your time zone.
How to set H
When you travel somewhere, set B to the correct time zone. To change H, select position two, and adjust H until the hour is correct (in +/- one hour increments). Note that M, S and T will continue to turn, so your watch will not lose time! Restore position zero when finished.
How to set T and M (and Stop S)
Move B so the arrow is above the crown (B=0). Select position three and adjust T to give the 24h time in GMT, where T is read against B's scale. You'll note that M moves when you rotate the stem, but S stays fixed. (S and M run at every position except three.) When done, restore position zero.
If you don't know what time it is in GMT, ask the United States Navy, a Global Positioning System (GPS) unit, etc. For our purposes, GMT is the same as Universal Time, although there are minor differences outside the scope of this article. (Select position three and turn the stem until you get the correct time.)
Once you set T, you will never have to change it again, except to adjust for error in the watch---T does not change with daylight savings time, for example.
________________ OR _________________
1. You pull the stem all the way out, and set the 24-hour hand and the minute hand to the proper time. Ignore the 12-hour hand and the date for now.
2. With the stem at the middle position, move the 12-hour hand around until the date is set, and the 12-hour hand is on the time you want. Of course it takes two times around for each advance of the date. It goes (relatively) quickly though, since the hand advances on one-hour clicks.
3. With the stem pushed in (but not screwed down, of course) wind the watch a bunch.
4. Screw down the stem
