I need a large digital display for the current time zone, a secondary display for UTC, a day/date display and that's about it. Synchronising through my phone for time updates to maintain accuracy and change zones as required is a big plus, and reasonable durability so I can go swimming and use it in the gym. I find a GMT hand on an analogue display can be difficult to read and prefer 00:00 digital. If I need a stopwatch when flying, there is one on my NAV display outside of flying a stopwatch and countdown timer are useful for parking meters.
Also I don't want something obviously valuable to make me a target for muggers or "Nice watch, where did you buy it ?" questions from customs officers. I can get what I need from CASIO at a reasonable price.
Early pilots watches were big for legibility and had large crown so they could be adjusted whilst wearing gloves. The modern smart functions are mostly a gimmick. Apple managed to turn the ordinary watch which did the job, lasted for years and could be repaired into an expensive, planned obsolescence item costing hundreds of dollars and needing to be replaced when the product cycle ran out.
