The newest Apple Watch is all about a big screen, a thinner case, and lighter metal options, allowing for better typing and easier viewing.

Apple's first wide-angle OLED display inside the Series 10 is 40 percent brighter than the Series 9. It allows for a wider variety of viewing angles. Its refresh rate, when idle, can update information from apps and complications once a second instead of the existing once-a-minute rate.
