Galaxy Watch8 is built for those who never settle when it comes to self-improvement. With a sporty yet sleek design, it packs a serious punch of enhanced performance, longer battery life and smart health tracking to keep you locked in to your health and wellness goals, wherever they may take you.

Your Watch8 works around the clock because a healthy lifestyle starts with healthy sleep. Advanced Sleep Tracking doesn’t just log hours, but it also takes a closer look at everything that happened while you snoozed. Wake up feeling lethargic? Get a full report on your sleep behavior, environment and disruptions, such as snoring.1 And when it’s time to get back on your feet for a new day and a new workout, you’re equipped with the insights you need to stay motivated with Energy Score. Need to multitask during your workout? Simply raise your wrist and speak naturally to send a text to meet up with a friend later, set a timer for your next mile or pull up your past run times.2

Watch8 is powerful and features an improved battery3 built to keep up with your longest bike rides without weighing you down. Thanks to a thinner, lighter body and dynamic strap system that molds to your wrist, you’ll almost forget your Watch is there as it tracks even the most intense workouts. Plus, the bright screen is visible even when you have to hit the trail in full sun.

Galaxy Watch8 is more than a watch — it’s a health coach and tracker that fits your wrist and your lifestyle.

1Phone must be within two feet of user with snore detection enabled through compatible Samsung Health app.
2Must have gesture settings enabled, be signed into your Samsung and Google accounts, and be connected to the internet directly (by Wi-Fi or LTE model) or via a compatible Samsung Galaxy AI phone. 3Based on typical use; results may vary.
