Before we saw the Apple Watch my guess on its form was a circular design that allowed a user to run their finger around the circumference to scroll.I suspect Apple Will eventually remove/delete the digital crown. I think it could be replaced with some type of ‘haptic Touch’ with some type of digital slider Implemented. Anyways, I get what you’re saying, I just think the digital crown doesn’t serve that much functionality aside from scrolling/double clicking, if They remove the digital crown, It would continue to strengthen the water resistance.
Having written a couple of watch apps now I'd be surprised if the crown disappeared.
How does that OPPO watch handle scrolling through options with 2 buttons and no wheel?
Think of setting a time in the timer app as a good example of Apple's picker UI.
