As an added benefit, with a flyer GMT like the Longines and the Mido shown in this story, if you travel to a new time zone, you can update the local time without changing the position of the 24-hour hand. So, if I were to travel to Geneva, I could land, jump the main hour hand +6 hours to show the time in Switzerland, and then rotate the bezel to place “19” at the noon position (19 being 24 minus the -5-hour offset for Toronto from UTC-0). Now, I have local and home time, and I only had to change the position of a single hand. In short, that’s pretty dang handy (and shown above).
