Apple Watch Series 9 is now even more capable, easier to use and faster thanks to the new and improved Apple chip. The new Apple Watch Series 9 GPS + Cellular MRMK3KS/A smartwatch has a dual-core processor with 5.6 billion transistors – 60 percent more than the S8 chip. The new quad-core Neural Engine makes operations up to twice as fast. It enables several innovations, such as a new gesture: the double tap. By tapping your index finger and thumb together twice, you can answer a call, open a notification, start or pause music playback, and more. Sapphire glass, a solid aluminum shell and a flat base make the Apple Watch Series 9 shockproof. It is also waterproof up to 50 meters. The Apple Watch Series 9 advanced system boosts the maximum screen brightness twice as high as the Series 8. The 2000 nit (LED screen brightness) screen is easy to read even in bright sunlight. The second-generation Ultra Wideband chip enables a new kind of integration with the HomePod app. When music is playing, Apple Watch Series 9 opens the Now Playing screen, where you can easily control your music playback. Ultra Wideband enables accurate tracking that can now guide you to your iPhone by showing its estimated distance and direction. As you approach your iPhone, tactile feedback, audio and visual cues help locate it. The flexible and durable pink elastomer bracelet is 160 - 210 mm long. The watchOS 10 update brings more content to your watch face than ever before. Almost every app is completely updated, and you get more information at a glance. When you turn the Digital Crown on any watch face, you'll see a smart stack of widgets with relevant and up-to-date information. Now information is also available on mental health and vision health, so you can monitor the well-being of your body and mind directly from your wrist.
