Actually, I want a watch to do a lot of things related to telling time, but not quite exactly the same.
I am frequently outdoors, and the first "other" feature I want is a rotating bezel, like a dive watch. When I start hiking into the wilderness, set this to zero. I want to know how long I have been hiking into the wilderness, so I have a good idea of how long it might take to get back out.
I like to have military hour markings on the watch face, so I can convert between 12-hr and 24-hr time easily.
I want a Sapphire crystal, so the face is durable.
I want analog hands and a second hand, so I can time things of a minute or two duration.
A Swiss Army watch with these features cost about $300 if I look hard on the internet. If the Apple watch can do all these things and then add a timer which will notify me by silently tapping my wrist, and a stopwatch function, I would be a happy camper.
As a general policy, it's best not to buy the first generation of any new technology. This is a very good debut, but it's still a first generation model.
