One of the standout features is sleep apnea detection, which monitors users' breathing disturbances during sleep. This functionality leverages the watch's accelerometer to track subtle wrist movements and analyse respiratory patterns, potentially alerting users to signs of sleep apnea.
Additionally, the Series 10 boasts a thinner design and larger display, with sizes now available in 42mm and 46mm. The redesign integrates the antenna into the case, allowing the watch to be just 9.7mm thick, which is a full millimeter thinner than its predecessor. The display has also improved with a wide-angle OLED screen that enhances visibility, making it easier to read information at a glance.
