ALL of them will do fine, Swatch owns them all more or less. I would challenge Jony to make an automatic movement that runs on fluid, like the Swiss have. Or hands in liquid that move by magnets, like the Swiss have, and those are the small makers.
I can remember when TVs and stereos came in fine wooden cabinets. And later in not-so-fine wooden cabinets. And by the 1970s, plastic or metal cabinets with fake woodgrain on them. And then that stopped. People wanted them to look like the electronics they are. And they wanted them as small an unobtrusive as possible. A TV may have an 80 inch screen, but no one wants a bezel you can see without a microscope.
Watches originated to tell time. And then they started making them more and more attractive according to the tastes of the day. And then their chief function - telling time - was taken over by phones so that the only people wearing them are those wearing them as jewelry.
And eventually, just as people realized if they want an attractive piece of furniture in the living room they should just buy one, people who want to wear expensive jewelry should stop pretending they care about it telling time.
Watches are going to pretty much die out, with or without Apple's help. And the iWatch will exist only as long as it takes to duplicate its functions even more unobtrusively.
the iMplant. All the function of an iPhone and iWatch in a simple implantable chip.
