By knowing the UTC offset of respective time zones, you can simply rotate the bezel to determine the time without ever adjusting the 24 hour hand.

This! This is the easiest for the frequent traveler. The GMT master instruction book suggests setting the 24hr hand to home time.. I like mine set to UTC, after all it is a “GMT Master” and not a “Home Time Master” Of course the regular hour hand controls the date so you can change that if you are there long enough if you want.
