What the 40mm GPS + Cellular model does

This Apple Watch Series 6 combines a silver stainless steel case with a white sport band and 32GB of storage. Cellular connectivity lets you call, text and navigate without carrying an iPhone. The S6 system-in-package runs up to 20% faster than the previous Series 5 chip. It is built for users who want independent connectivity in a compact 40mm form.

Health sensors and always-on display

The new blood oxygen sensor and app measure SpO2 levels on demand. An electrical heart sensor enables the ECG app to check heart rhythm. The LTPO OLED Always-On Retina display is 2.5x brighter outdoors when your wrist is down, so metrics stay visible without raising your arm. Fall detection and Emergency SOS add automatic safety alerts.

Stainless steel build.

The stainless steel case resists everyday wear and pairs with the included white sport band via Apple's quick-release mechanism. Water resistance is rated to 164 feet, supporting swimming and shallow-water activities. 5GHz Wi-Fi and the U1 Ultra Wideband chip improve wireless range and precision finding. The Digital Crown provides haptic feedback for tactile navigation.

Questions about this item

How often will the White Sport Band need replacing?

Apple does not publish a replacement interval; swap the band when you notice stretching, cracking or skin irritation.

What stops the S6 SiP from running at full speed during long workouts?

The processor will throttle once its thermal envelope is reached; no sustained-performance wattage is published.

How loud does the speaker get when taking calls all day?

Apple gives no sustained-output decibel figure; the speaker is designed for wrist-level voice calls and alerts.
