Samsung Galaxy Watch Ultra (2025)

Titanium, sapphire, 10ATM, and the longest battery Samsung makes. A spec bump, not a new watch.

The 2025 Ultra is a refresh, not a redesign — same hardware as the 2024 model with storage doubled to 64GB, a Titanium Blue finish, and One UI 8 Watch in the box. What the money buys is the chassis: grade 4 titanium, sapphire crystal, 10ATM, MIL-STD-810H, and a 9,000m altitude rating, wrapped around the biggest cell Samsung ships. Eighty hours with the always-on display off is the best battery in the Galaxy line, though a Garmin still laughs at it. The full sensor stack carries over, including Antioxidant Index and blood pressure. In the US it comes one way only: 47mm, LTE, $649.99.

Strengths

  • 80 hours claimed, 100 in power saving — the best in the Galaxy line
  • Titanium, sapphire, 10ATM, MIL-STD-810H
  • Antioxidant Index, BP, ECG, and BIA with no subscription

Tradeoffs

  • Hardware is identical to the 2024 model — storage and colour aside
  • Roughly two hours to charge from empty
  • LTE-only at $649.99, with no cheaper Wi-Fi configuration
