Series 10 is a major milestone for Apple Watch. It features our biggest and most advanced display yet, showing more information onscreen than ever. With Apples first wide-angle OLED Display, the screen is brighter when viewed from an angle, making it easier to read with a quick glance. Series 10 is our thinnest watch ever. To make this possible, we re-engineered nearly every aspect of it, including the SiP, Digital Crown, speaker, front crystal, and antenna. It all comes together to create a watch thats packed full of innovation. Series 10 has the largest screen area of any Apple Watch. It has up to 75% more screen area than Series 3 and up to 30% more screen area than Series 4, 5, 6, and SE. So you can see and do even more. For the first time, Apple Watch comes in an eye-catching Jet Black aluminum. The case is polished until its extremely reflective. It then goes through a 30-step anodization process to create a deep, glossy black thats truly striking. The result is a timeless, sophisticated look. In another exciting first, you can choose from three polished titanium finishes that are as beautiful as they are tough. Theyre made of aerospace-grade titanium thats polished to a mirror-like shine. With titaniums remarkable strength-to-weight ratio, Series 10 weighs almost 20% less than Series 9 in stainless steel while still being extremely durable. From sleep tracking to heart health notifications and much more, the advanced sensors in Series 10 help you better understand your health. Sleep apnea is a condition where breathing stops repeatedly and causes disrupted sleep. If untreated, it can lead to hypertension, type 2 diabetes, and cardiac issues.
