There are Swiss watch companies other than Rolex. Most of those are not nearly as strict with their brand. If anything, the other companies might create smartwatches. Rolex will not. IF Rolex were to create a smartwatch, they would likely produce it under their Tudor brand--NOT Rolex.
You misunderstand my point. The Swiss used to have essentially a monopoly on watch manufacturing, because it required fine craftsmanship that they had down pat, and no one could do it anywhere near as well as they could. Then as simple computer chips were coming out, it was realized that one could make a digital watch (even if it still has an analog face, most modern watches are digital underneath, not run by gears). If I remember correctly, the Swiss were even the first to create a concept model of a digital watch, but they also dismissed it as just a concept/fad, and didn't pursue it. The Japanese and others did, and thus the Swiss did not follow the paradigm shift, and they lost the vast majority of their market share. (Perhaps ironically, Rolex now capitalizes on being one of the very few that still do things the old way, and have managed to use their existence in that niche to command a premium price. I agree that Rolex is unlikely to do a smartwatch, because it would be far removed from their niche.)
The same loss of market share could easily happen to current companies known for making watches if they dismiss these much more interactive smartwatches. In 5-10 years time, it's conceivable that most folks will have some type of smartwatch (even if some may end up being of a more mild variety, while others become much more advanced), and a large number of manufacturers who currently are big names in watches could be gone.
