That's a smartwatch. Obviously you need an incentive to wear it continually; that could be exercise (step counting), health tracking (heart rate plus (as of a few months ago) pulse oximetry), etc.

Also you can get contactless payment, and it can even tell the time.

After a few months you get used to wearing a watch continually again.

That's an option, but I hate watches. Always have for some reason, even when it was the only portable accessory I had it in my pocket.
