Apple Watch Series 8 GPS 41mm Midnight Aluminum Case with Midnight Sport Band - S/M

Apple Watch Series 8 offers all the great features you love, like an expansive display, great durability, fast charging, and industry-leading health capabilities. And it has two new sensors for even more heath and safety features. A temperature sensor enables advanced insights for cycle tracking, and a high-g accelerometer works with an improved gyroscope to detect severe car crashes and get help if you need it. Apple Watch Series 8 also offers advanced workout metrics, a Low Power Mode that extends battery life, and a redesigned Compass app.

Edge-to-edge display with narrow borders has almost 20 percent more screen area than Apple Watch SE

Bright Always-On Retina display so the screen is easy to read

Front crystal is crack-resistant so you don’t have to worry about drops

Fully dust resistant with IP6X certification

Swimproof with a water resistance 50 meter rating

Sensor samples wrist temperature overnight and tracks nightly shifts from your baseline temperature so you can see changes that could be caused by exercise, jet lag, illness, or other factors

Changes in temperature can reveal the biphasic shift, an increase in temperature that can indicate ovulation—so the Cycle Tracking app can estimate when ovulation occurred, which is valuable information for family planning, and provide improved period predictions

Sensor and app measure the oxygen saturation of your blood, an important indication of how well your body is absorbing oxygen

Periodic readings are taken in the background, even while you’re sleeping, recording your blood oxygen trends over time

Electrodes in the Digital Crown and back crystal work with the ECG app to read your heart’s electrical signals and generate an electrocardiogram

Apple Watch can check your heart rhythm in the background and alert you to an irregular rhythm that appears to be atrial fibrillation (AFib)

AFib History in watchOS 9 can estimate how frequently your heart is in AFib and track lifestyle factors that may affect your condition

With the optical heart sensor, you can check your heart rate at any time and see your resting, walking, and post-workout heart rates

High-g accelerometer and improved gyroscope work with the barometer, microphone, and GPS to detect severe car crashes, like front-impact, sideimpact, rear-end collisions, and rollovers

If a crash is detected, Apple Watch sends you a notification—and if you don’t respond, it automatically calls emergency services, gives them your location, and notifies your emergency contacts

Enjoy all-day, 18-hour battery life

Get up to 36 hours of battery life with your iPhone present using Low Power Mode, which maintains core features while selectively disabling others

Fast-charge from 0 percent to 80 percent battery in just 45 minutes

Get new metrics like heart rate zone, power, and vertical oscillation

Tailor your routine with Custom Workouts

Multisport workouts automatically switch between swim, bike, and run

Coming soon in watchOS 9, Apple Watch can automatically detect when you’ve arrived at a track, so you get the most accurate running metrics

Redesigned Compass app features hybrid, technical, and orienteering views to help you find your way

Set Compass Waypoints to mark key locations, like a trailhead, and view them as a watch face complication to see heading and distance at a glance

If you’re lost or disoriented, Backtrack uses GPS to create a historic path of where you’ve been—and Backtrack automatically turns on if you’re away from all Wi-Fi signals and not in a known location

Get additional insights into your sleep with sleep stage tracking

Apple Watch will detect when you’re awake or in REM, core, or deep sleep

41mm cases work with 41mm or smaller bands, and 45mm cases work with 49mm and 45mm or smaller bands

Available in midnight, starlight, silver, and (PRODUCT)RED 100 percent recycled aluminum, and graphite, silver, and gold stainless steel
