Rolex is known for innovative and high-quality watches. Unfortunately, some of their features are confusing to use. The Rolex GMT Master includes a world time function. It isn't automatic, but once it's set, you can keep track of your home time regardless of where you are in the world. To use this feature, you must first set up the correct conditions. One set, the only thing you should ever have to change is the local time.

  1. 1

    Familiarise yourself with the four crown positions. Position zero is with the crown fully pushed in and tightened. Position one is with the crown unscrewed, allowing you to wind it. Position two is with the crown pulled out to the first position, allowing you to adjust the hour hand. Position three, with the bezel pulled out to the second notch, allows you to move both the minute hand and the 24-hour hand.

  2. 2

    Set the bezel. This is the outer ring that you can rotate. Start with the bezel pointing at the 12:00 position, toward the top of the watch. To set the bezel correctly, you will need to know how many hours east or west of Greenwich Mean Time (GMT) you are. If you are west of Greenwich, rotate the bezel clockwise the number of hours you are from Greenwich. If you are east of Greenwich, rotate the bezel counterclockwise the correct number of hours.

  3. 3

    Set the crown at position two, and rotate the crown to set the local hour.

  4. 4

    Set the crown to position three, and rotate the crown to set the correct minute. Once the time reaches the seconds indicated on the watch, return the crown to position zero. The second hand will begin to move, and the time is now set for your local time zone.

  5. 5

    Set the watch's time for travelling. Rotate the bezel to the correct position according to your location from Greenwich. For example, if you travelled from Los Angeles to New York, you will need to rotate the bezel three hours counterclockwise, since you are now closer to Greenwich. Unscrew the crown and pull it out to position two. Set the local hour by rotating the crown forward or backward. This will not affect the minutes or seconds. Return the crown to position zero.

  6. 6

    Set the 24-hour and minute hands. Rotate the bezel so it's pointing at the crown. Select position three on the crown, and rotate the 24-hour hand until it is opposite the bezel arrow. The watch is now fully set.

  7. 7

    Adjust the watch by placing the crown in position three and adjusting to the correct time. Replace the crown to position zero when the correct seconds are reached.

  8. 8

    Correct the date by placing the crown in position two and rotating it until you reach the proper date. Stop the hour hand at the correct hour. The watch does not automatically adjust for months that have fewer than 31 days.
