I am not sure how you can call the watch a failure....
With 2 million units pre sold at a cost of at least $350 each, you are looking at roughly $700,000,000 in revenue... in reality not everyone would have bought the cheapest option so so far they have netted over a BILLION dollars in revenue... so its hard to call the thing a flop... They have certainly more than made up all their R&D, Marketing and Production costs already.
So, even if the thing never sells another unit because those owners all decide it stinks, and no one else buys one, it can’t be considered a failure, at least fiscally.
Reality is, sales aren’t going to dry up... will it be a game changer? Who knows... but even if they never sell another one, they haven’t wound up in a worse financial position.
The watch is a failure when it’s touted as the end all be all prop-up for 2015 by a listless, non-diversified single product corporation run by a militant hippy queer.
You can be sure that any company doing that will fail.
