The Apple Watch now generates more revenue than the entire Swiss watch industry combined. Apple is the largest watchmaker in the world both by revenue and by units sold.
If you wanted to count apples share of the watch industry, not just the swiss watch industry) it would be less than one percent.
It's making a new market and gaining some ground but it's not the 'watch industry killer' that people like to make it out to be.
Smartphones and tablets existed, but consumers didn't buy them in today's numbers until Apple/Android came along.
So I'm not sure how this is relevant.
It would also probably be fair to say that the swiss watch industry was decimated as carrying a phone became ubiquitous.
I think the comparison is relatively apt though. People have one left wrist, and even though the apple watch and a classic watch are different categories. You don't often see people wearing both. So there is competition there for a limited number of wrist slots.
And apple is selling more units than team swiss watch.
Now, if you wanted to have a conversation about total wrist market share, I'd still guess the swiss watch industry is winning. You don't have to buy a new mechanical watch every other year so units moved isn't as apt a comparison.
