When you travel and land in another timezone you will need to adjust the local time.
Pull the crown out to position 1. It is a very subtle click so be careful to ensure you
are not pulling it to position 2.
Set the hour hand to whichever timezone you are actively in. The hour hand jumps
in 1 hour increments so be sure you are paying attention to am/pm. In this example
the local time needs to be adjusted to San Francisco time, which is 2 hours behind
Dallas time. As you adjust the hour hand, the 24-Hr hand will remain in place as it
continues to keep track of your home time.

You can also keep track of a 3rd timezone utilizing the rotating bezel.
If you know the time difference between your Home Time and the 3rd timezone
you’d like to track, simply turn the bezel so the 24-hr hand is pointing at the
appropriate hour indicated on the bezel. In this example, the time in London is
+6 hours from Dallas time. To refer back to your Home Time, simply rotate the
bezel to the neutral position with the 24 at the 12:00 position.
