My hundred buck Casio shows UTC and local (world) time. That’s all I really want or need - something I can check at a glance (digital) and run my life by, as well as check local time when booking taxis etc. Flying deep nights it also helps answer that age old freight dog question: “what day is it?” as it clearly shows the date/day.
A very dear friend, sadly now passed, had a citizen Navihawk. Lovely watch, and I have to say the built in Nav whizz wheel was kind of cool for working out times when trundling round together in GA aircraft, and in that respect did more than my old Casio ever could.... but using the old 1.5 miles a minute for 90 knots, 2 miles a minute for 120 or 2.5 miles a minute for 150 was just as good, and it was just a novelty really.
