A watch is more jewellery than timekeeping appliance. Appearance and provenance/authenticity seem key. (You can tell this is the case, because people will spend thousands of dollars on wind-up watches that stop telling the time entirely after 2 days or whatever - even though they could instead have bought some cheap digital POS for £5, that will require adjusting about once a year.) And there's not much in the way of provenance for a computer-powered wristwatch from Apple... so the review focuses, and quite rightly I think, on what the watch looks like, and how it feels on the wrist.

The timekeeping aspect is purely secondary, since, thanks to modern technology, we know it will keep the time. My phone keeps the time, my laptop keeps the time, my TV keeps the time, my fucking oven keeps the time. Keeping the time is a solved problem.

There are only a couple of options in your list that's synced to a reasonable timekeeping source - keeping accurate time is something we only solved "recently"*

*Although, in the US, wasn't there a timekeeping radio broadcast?

There still is: http://en.wikipedia.org/wiki/WWVB

I remember having a cheap Timex in the mid 2000s that synced off this. I found it a great improvement to the watch experience; my synchronization source of choice before that was a wall clock also powered off that same signal. I also have vague memories of a phone number you could call to get the accurate time.
