Even as someone who's owned GMT watches, I can understand the confusion. They should put the numerical hour markers on the digital "bezel." If you're gonna go skeuomorphic, you may as well go all the way.

The missing 24-hour makers is the source of the confusion and also why I don't like it. The second time zone is too hard to read fast

I like the look of this watch face, that's why I chose it.
It's just confusing why the red pointer remains on, when there is no second time zone set.
I also like the look and use it only to see visually the sun rise and sun set times.

Originally created for pilots flying across many time zones.

An interesting thread!:)
For those few reading this who may be interested in both Apple and automatic GMT watches in general, here’s a very special, somewhat rare 12 hour-GMT complication from my collection, marketed from ’69 through the early 1970’s, a model that has unfortunately more or less fallen into oblivion.
This radical chronograph is the iconic Omega Flightmaster, purpose built for pilots (with their frequent change of time zones) also used in space missions. It features 3 crowns and 2 pushers (all colour-coded to their function), and no fewer than 7 hands!

One blue 12-hour GMT hand moves uni-directionally and is set via a blue colour-coded auxiliary crown located at the 10 o’clock position. By turning the blue crown, the blue spacecraft-shaped hand can be set at any other time (for example GMT) and at a glance one knows the time in two places at once.
An unusual, totally enclosed internal bezel (black with white markings) can be turned clockwise or anti-clockwise by use of the black colour-coded crown on the outer casing at 8 o’clock position).
The main white hour and minute hands (set by the crown winder at 3 o’clock) are keyed to a small sub-register at the 9 o’clock position which features a special 24hr AM/PM indication.
The buttons at the 2 and 4 o’clock position (colour-coded yellow/orange) are for the chronograph functions, the former starts the main, long red centre second hand, which is keyed to a minute totaliser sub-dial (at centre 3 o’clock) and an hour totaliser sub-dial (at centre 6 o’clock) recording up to 12 elapsed hours. The button at 4 o’clock, returns the centre second hand and totalisers back to zero.
Aside from the additional complications indicated above, the movement caliber 910 is based on the Lemania 1873 /Omega cal.861 manual-wind, immortal Speedmaster Moonwatch.
One of Omega’s priorities in the late 60’s was to show the market the superiority of their 12 hour-GMT model in relation to other popular GMT watches, the Rolex GMT or the Glycine Airman.
Omega produced 2 versions of the Flightmaster, and it’s taken me over 20 years to find an excellent boxed example of the 'sister' watch, cal. 911, seen below.
