I guess my synapses aren't firing too swiftly today. Would you explain
how the procedure above is easier or more convenient than simply adding 7?


I haven't found converting from local to UTC difficult. However, it's
certainly more complicated than adding an integer to the hours.

You have to account not only for Daylight Saving Time (which would
presumably be accounted for in such a watch), but also for roll-over of the
time (e.g. if you're in a UTC-7 time zone, any time after 1700 will require
the subtraction of 24 from the resulting number to get the actual time).

Furthermore, if you are a pilot, you can easily find yourself in a different
time zone, with a different integer to add. Having a watch do the
calculation for you may avoid accidently adding the wrong integer, or adding
the correct integer wrongly. UTC will be UTC no matter what time zone the
primary display of the watch is set to.

How useful having to push a few buttons to do that computation rather than
doing in oneself, I suppose that depends on the individual. Your mileage
may vary. But obviously for Jay, it's something he finds useful, so
it's good he has a watch that does that for him.
