Hard to say if if

watch will be a bust or not IMO. I am certain that the launch will have it's surge of *must have the device first* clientele who will not blink at the price, and brave camping out to be first in line to get it upon it's launch.
The question in my mind is whether the

watch will develop into a worldwide adoption phenomena - or not, as the marketing strategy of

these days seems a little fractured to me in some ways - ie: bigger and thinner is better and lighter (iphone 6 plus), smaller and fatter is incredible and functional -(

watch.) combine bigger is better and lighter with smaller incredible and fatter equates to what exactly, I am not really sure.
It is hard for me to imagine that the iphone 6 crowd who would never return to what they deem is a tiny interface with the 4S or 5S would be overjoyed to deal will an even tinier digital watch interface, which would save them from using the 6 plus as it is unwieldy now?... confusing to me.
Target demographics I imagine would be the younger generation who do not bother wearing watches ?..doesn't make sense... unless

wants to propel the next generation of watch wearers (only

watches of course) , remains to be seen if that is successful.
Then there is the watch wearing crowd, many who wear one for work related necessity (yes it is faster to glance at a watch rather than pulling out your iphone and swiping to see the time) who ususally buy watches that are affordable and functional, not sure that crowd set would enjoy having to charge their watches everyday just to have it linked to their phones and pay the asking price for such a device then have to pay for applecare which does not cover accidents..
Then there is the watch aficionado and or collector who choose watches are the epitome of mechanical design and craftsmanship, who some would probably buy the

watch as a curios watch related object, but most IMO would not.
Lastly I would ask..is it serviceable, is it glued? watch maintenance is always a necessity, from digital batteries to mechanical overhauls.. While digital batteries are cheap and can be serviced anywhere, mechanical maintenance is more expensive but is justifiable as mechanicals are clear investments in historical and timeless (pun intended) examples of enduring craftmanship excellence.
So I question the strategy of maintenance as well - Applecare for a watch? which demographic will not mind paying for it and when Applecare runs out or the watch accidentally breaks...then what? If the tech of the watch is obsolete after 3 years and Apple stops maintaining or supporting the device after 5 years, then what..paper weight?
I guess the answer would be to *upgrade* and re-sell, but with non serviceable items, re-sale in the long run will not be good IMO...especially a watch who's servicing days are numbered from the beginning...much like most of Apple's devices lately.
So hit or run.. not sure.. but not a *hit* for me. being a mechanical loving fiend.
