Smartwatches / Samsung
Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium)
60 hours with the always-on display actually on, and the brightest screen on any wrist.
Overall score 7.8/10
Pros
- + 60 hours quoted with the always-on display ON — the only maker here that states the harder number
- + 5000 nits is genuinely twice as bright as the brightest Apple Watch
- + 10 ATM plus EN13319 dive certification and IP69K, on a Wear OS watch with Play Store apps
- + LTE included rather than a $50 upcharge and a second ASIN
Cons
- − Same iPhone lock-out and the same non-Samsung Android feature loss as the Galaxy Watch9
- − $699.99 buys you a watch whose blood-pressure headline feature is not FDA-cleared
- − The dive app was still 'coming later in 2026' at launch — you are buying a promise
- − 47mm titanium is heavy, and Samsung will not replace the battery
Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) review: what the specs say
60 hours with the always-on display actually on, and the brightest screen on any wrist. At $699.99, Samsung's 2026 model sits at the premium end of the category — the smartwatches we compare run from $79.99 to $799. It scores 7.8/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Display at 9.6/10 — panel type, brightness, always-on behaviour and legibility in sunlight. The weakest is Ecosystem Freedom at 2.5/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: same iPhone lock-out and the same non-Samsung Android feature loss as the Galaxy Watch9; and $699.99 buys you a watch whose blood-pressure headline feature is not FDA-cleared. Every specification on this page comes from Samsung's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| Phone Compatibility | Android only. Requires Android 13 or later with 1.5 GB RAM minimum. No iPhone support. On non-Samsung Android you lose ECG, blood pressure, SmartThings camera feeds, Camera Controller and DND/bedtime sync — the same list as the Galaxy Watch9. |
| Claimed Battery Life | 60 hrs |
| What the Battery Claim Assumes | Samsung's 60-hour figure is quoted with the always-on display ON, which is unusually honest for this category — but it is still a mixed-use claim, not a workout claim. Continuous dual-band GPS and LTE-only use (with the phone left behind) drain it far faster. |
| Case Size | 47 mm |
| Display | 1.52-inch Super AMOLED under sapphire crystal, up to 5000 nits — the brightest smartwatch display sold |
| Operating System | Wear OS (One UI Watch) |
| Third-Party Apps | Google Play Store on the watch, same Wear OS catalogue as the Galaxy Watch9 |
| Health Features Enabled in the US | ECG, irregular rhythm notifications and sleep apnea detection are FDA-cleared. Blood pressure rolled out in the US from 31 March 2026 but is not FDA-cleared, is Samsung-phone gated, and needs 28-day cuff re-calibration. BIA body composition included. |
| Subscription Wall | No subscription for core metrics; bundled third-party fitness trials auto-renew at full price. |
| LTE Option | Not an option — LTE is built into every Ultra2 and included in the $699.99 price. You still pay a carrier for the line. |
| Water & Dust Rating | 10 ATM (100 m), IP69K, MIL-STD-810H, EN13319 dive certified to 40 m |
| Battery Replacement | No consumer battery-replacement programme; the titanium case is sealed. |
| Connectivity | LTE (included), Bluetooth, Wi-Fi 2.4/5GHz, NFC, Dual-band GPS L1+L5 |
| Material | Titanium case with sapphire crystal front glass |
| Warranty | 24 months |
