DESIGN

Rugged luxury

Design as bold as it is polished. Rooted in the heritage of our iconic cushion design, Galaxy Watch Ultra2 continues that legacy into something tougher and more refined, built on the principle that a watch should push you forward, not get in your way.

Titanium tough enough for impact, light enough to forget you're wearing it. A slimmer, seamless profile paired with an even bigger battery. More intuitive buttons that are hard to miss. And an Air Pocket Marine Band that keeps your wrist dry whatever the conditions. Bold in build. Polished in every detail.

OUTDOOR EXPERIENCE

The ultimate Galaxy Watch to push your limit

Off-grid. On track

Galaxy Watch Ultra2 takes trail running further. Unlike road running, trail running is unpredictable by nature — the path turns without warning, the climbs are harder to pace and the further off the grid you go, the more guidance you need. Galaxy Watch Ultra2 keeps you on track and in control — from the first step to the last.

SAFETY SIREN

Heard up to 180 meters

When you need help but you have no clear sight of others, your voice can only carry so far.

ENERGY SCORE

Push or pause? Energy score tells you

Some mornings you're ready to push hard. Others, you're still recovering from last night's client dinner or late gym session.

SLEEP APNEA

Waking up tired even after a full night's sleep is a sign to pay attention to. Galaxy Watch Ultra2 detects signs of moderate to severe obstructive sleep apnea by monitoring your blood oxygen levels throughout the night. Stop guessing why you're tired and uncover what's happening during your sleep.

HEART HEALTH

Your daily compass for heart health management
