Apple launches Watch Series 12 and Ultra 4 with advanced health sensors

Apple has officially opened preorders for its latest wearable lineup, the Watch Series 12 and the Watch Ultra 4. Both models are powered by the new S11 chip, which serves as the foundation for a redesigned Health Sensing System. According to Apple, this integration enables the most accurate heart rate monitoring ever featured in a wearable device. The new hardware allows for higher-frequency tracking of heart rate and heart rate variability (HRV), providing users with more granular health data than previous generations. The devices will launch running watchOS 27, further integrating these advanced sensing capabilities into the Apple ecosystem. These updates represent a significant hardware iteration focused on improving biometric precision for fitness and health monitoring enthusiasts. The watches are available for preorder now, marking the latest expansion of Apple's wearable technology portfolio.
