Apple Watch Series 10 42MM Jet Black Aluminum GPS – Black Sport Band

In addition to being thinner, Apple Watch Series 10 is also lighter: Aluminum cases weigh up to 10 percent less than Series 9, and titanium cases weigh almost 20 percent less than stainless steel Series 9. The case also features more rounded corners and a wider aspect ratio.

Apple’s Largest, Most Advanced Wearable Display
The display on Apple Watch is central to every interaction, from viewing a notification, to taking a quick glance at workout metrics. Apple Watch Series 10 features the biggest and most advanced display of any Apple Watch.

Apple Watch Series 10 is the first Apple product to offer an innovative wide-angle OLED display, which optimizes each pixel to emit more light at wider angles. As a result, the display is up to 40 percent brighter than Series 9 when viewed from an angle, making it easier to read at a glance.

The wide-angle OLED display is also more power efficient, enabling a faster refresh rate when Apple Watch is in always-on mode, going from once a minute to once a second. As a result, users can now see a ticking seconds hand without raising their wrist on select watch faces.
