I took a short video of the Airline jumping through GMT hours - it definitely seems to "ignore" the 24-hour bezel as it moves along a 12-hour scale.

: Thanks for your reply, Heinz!
: If you're familiar with this particular obscure Heuer (made over
: the course of the transition and found both as "Heuer"
: and "TAG" branded), you'll know that while it features
: a 24-hour adjustable bezel and fixed 24-hour rehaut, the GMT
: hand, adjustable at 10 o'clock, independently, runs as a 12-hour
: hand, synced with the hour hand. The pusher allows for only
: one-hour jumps along a 12-hour scale. That is why I'm confused.
