Of course newer versions of the watch allow some additional flexibility in the use of the fourth hand, but the original purpose is still valid.

No, no, no.......The original GMT was intended for pilots to keep track of their HOME time... (GMT is just the name of the watch....not the hand or it's intention)
The watch was set to HOME time.... both hands, since they were synced. The bezel was rotated to each new time-zone to keep track of where you are in the world, but the pilot kept a home reference to sleep by and manage jet lag... That was the whole point for Pan Am's request to Rolex for development of the watch..
