Apple Watch Series 12 (GPS + Cellular, 42mm)

Compared with the Apple Watch Series 11 (GPS + Cellular, 42mm), this model has the S11 chip and a redesigned set of optical and electrical heart sensors. It reads heart rate and heart rate variability far more often in the background. Aluminum models replaced Ion-X glass with Ceramic Shield 2, which Apple rates 60% tougher, and fast charging gives 12 hours of use in 15 minutes. Cellular models came in aluminum, titanium or ceramic, which returned for the first time since the Series 5.
