The redesigned Apple Watch Series 10 is the thinnest Apple Watch with the biggest display ever, making it an incredible upgrade over Series 6 and earlier. It comes in beautiful finishes-including jet black, the first-ever polished aluminum finish on Apple Watch, and jewelry-like polished titanium. Series 10 is packed with advanced new features like Sleep Apnea Notifications, a depth gauge, water temperature sensor, and the Tides app. Its also the fastest charging Apple Watch ever-in just 30 minutes, you can charge up to 80 percent battery. Series 10 has improved call quality, and media playback through the speaker, and both cases-aluminum and titanium-are carbon neutral.
