I think the way Apple's GMT watch face works is confusing (and different to most GMT watches). Many of the responses on this thread are not quite right and people are unnecessarily confused by the implementation.
Below I will refer to the alternate time as GMT (it could be any alternate time choosable).
The way most GMT watches works (and how I think the Apple GMT Face should work) is like this:
- Separate bezel numbered up to 24
- The GMT bezel doesn't have to move (and usually doesn't)
- The GMT hand indicates the 24 hour time
- If it is12 noon GMT the GMT hand would point straight down (to regular the regular 6 is)
Currently the Apple GMT Watch Face GMT bezel rotates (apparently to indicate offset from your current time zone) and the GMT hand only goes between 1 and 12 with the colour of the GMT bezel used as a guide as to whether it would be night or day (am/pm).
Apple could rectify the issues by changing to the regular method I have described or at least providing the option to have a fixed or offset GMT bezel in the face options.
An important user group of watch faces like this are pilots who use UTC for precise, reliable and consistent time sharing. For pilot's the world over the time is the same (UTC time) and it is stated in 24hr format. Apple, please label the GMT bezel up to 24 or have the number in the circle (at the end of the GMT hand) going from 00 up to 23. eg. 15 minutes after midnight UTC is zero zero one five (WATCH should show 00) and 1045pmUTC is 2245 (should show 22). Hopefully you get the idea.
