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.*

[Battery]
*Battery life is based on results from internal lab tests for typical usage pattern scenarios conducted by Samsung. Actual battery life may vary depending on different usage patterns, device model or the battery manufacturer. Typical value tested under third party laboratory condition. Typical value is the estimated average value considering the deviation in battery capacity among the battery samples tested under IEC 61960 standard. Typical capacity is 800 mAh (35 % increase compared to previous Galaxy Watch Ultra). Actual battery life may vary depending on network environment, usage patterns and other factors.
*Fast charging speeds are based on internal laboratory tests conducted under the following conditions: room temperature, Airplane Mode enabled, using the dedicated wireless charger (EP-OL715), and a 5V/2A PD Power Adapter (TA). Actual charging speeds may vary depending on individual usage, charging conditions, and other external factors.
