In addition to the iPhone XS leak, information about the Apple Watch Series 4 was posted on 9to5Mac. A marketing render was posted along with it, and it looks… awesome:
The new Apple Watch S4 will feature the same basic design as the three previous generations, and it’ll also use the same bands. The new OLED displays will occupy much more of the watch’s face though, and the case looks much thinner than it is on the current models. There are also some hardware changes like the addition of a mic on the right side, the possible addition of a UV sensor (though that complication might just be location-based), and the Apple Watch Series 3’s hideous red dot is gone from the crown and replaced by a more subtle red ring.
