Apple Watch Series 12 GPS 42mm Aluminium Bronze Sport Band Black M/L

The Apple Watch Series 12 marks a major step forward for connected health by offering the most accurate heart rate sensor ever built into a smartwatch. Thanks to its brand-new Health Sensing System paired with the S11 chip, it now measures heart rate every five seconds throughout the day, providing continuous, detailed insight into the user's physiological state. Heart rate variability, a key indicator of stress and recovery, is now measured up to 24 times more often than before, with a distinction between recovery HRV and overall HRV for a more precise read on cardiovascular health.

This new generation also introduces the readiness score, a brand-new feature that analyzes recent activity, training load, vitals, and sleep quality to deliver a clear score out of 10, paired with a concrete recommendation: recover, pace yourself, ready, or go for it. This score updates throughout the day as new data comes in, helping users better plan their day.

On the battery side, the Apple Watch Series 12 maintains up to 24 hours of everyday battery life and now offers up to 10 hours of battery life during an outdoor workout, 25% more than the previous model. Fast charging delivers up to 12 hours of additional battery life in just 15 minutes. Step tracking has also been redesigned with new machine learning algorithms, offering the most accurate step count on the market, along with a new dedicated complication directly accessible on the watch face.

The Apple Watch Series 12 also introduces Audio Intelligence features, built with privacy at their core thanks to the S11 chip and its dedicated Secure Exclave. These include: Sound Recognition, which alerts deaf or hard-of-hearing users to doorbells, sirens, or a baby crying; Live Rewind, which lets users replay the last 15 seconds of a conversation with a simple double press of the Digital Crown; Siri Recap, which generates conversation summaries so nothing gets forgotten; and Shazam, which instantly identifies surrounding music.

With watchOS 27, the watch also integrates Siri AI, a completely reimagined version of the assistant, capable of understanding the user's personal context right on the wrist. The case is available in aluminum, titanium, and for the first time in ceramic, with aluminum models now protected by Ceramic Shield 2 glass, 60% more scratch-resistant than the previous generation.
