Side-by-Side Comparison
| Spec | Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) | Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) |
|---|---|---|
| Price | $699.99 | $799.00 |
| Release Year | 2026 | 2025 |
| 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. | iPhone only. Requires iPhone 11 or later on iOS 26. Satellite features additionally require the watch to be out of cellular range, and are US/Canada-region dependent. |
| Claimed Battery Life (hrs) | 60✓ | 42 |
| 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. | Apple's 42 h figure assumes the always-on display active and a mixed-use day with one workout; 72 h is Low Power Mode with the always-on display disabled and some sensors throttled. Multi-hour GPS workouts and satellite use pull it down sharply. |
| Case Size (mm) | 47 | 49 |
| Display | 1.52-inch Super AMOLED under sapphire crystal, up to 5000 nits — the brightest smartwatch display sold | LTPO3 wide-angle OLED, always-on, up to 3000 nits |
| Operating System | Wear OS (One UI Watch) | watchOS 26 |
| Third-Party Apps | Google Play Store on the watch, same Wear OS catalogue as the Galaxy Watch9 | Full on-device App Store — the same native watchOS catalogue as Series 11, plus dive and outdoor apps that use the depth sensor |
| 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. | Live in the US: ECG, irregular rhythm notifications, sleep apnea notifications and hypertension notifications (all FDA-cleared), plus wrist temperature and a depth gauge. Blood Oxygen is the post-Masimo redesign — sampled on the watch, computed on the iPhone. |
| Subscription Wall | No subscription for core metrics; bundled third-party fitness trials auto-renew at full price. | None required. Satellite features are included with the hardware, not sold as a subscription. |
| 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. | Not an option — 5G cellular is included in every Ultra 3 and is part of the $799 price. A carrier line is still required and billed separately. |
| Water & Dust Rating | 10 ATM (100 m), IP69K, MIL-STD-810H, EN13319 dive certified to 40 m | 100 m water resistant (WR100), IP6X dust, EN13319 dive certified to 40 m |
| Battery Replacement | No consumer battery-replacement programme; the titanium case is sealed. | Apple out-of-warranty battery service is a flat $99, the same as the aluminium models. |
| Warranty | 24 months | 12 months |
| Colors | Titanium Gray, Titanium Silver | Natural Titanium, Black Titanium |
Category Scores
Battery Life
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) is marginally ahead, 7.8 to 7.5. A gap this small rarely decides a purchase on its own, though it counts if real endurance between charges, judged against what the claim actually assumes rather than the headline number is your priority.
Health Tracking
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) leads clearly here, 9.6 against 8.8 — a 0.8-point margin on depth of heart, sleep and body metrics that are genuinely enabled and cleared for use in the US. If that is what you are buying for, the Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) does not close the gap elsewhere.
Fitness & GPS
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) is marginally ahead, 9.4 to 9.0. A gap this small rarely decides a purchase on its own, though it counts if workout tracking, GPS accuracy, sport modes and training analysis is your priority.
Ecosystem Freedom
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) leads clearly here, 2.5 against 1.0 — a 1.5-point margin on the category's trap dimension: how much of the watch still works on a phone other than the maker's own. 10 means full parity on iOS and Android; 1 means one phone brand or nothing. If that is what you are buying for, the Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) does not close the gap elsewhere.
App Ecosystem
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) leads clearly here, 10.0 against 8.5 — a 1.5-point margin on whether there is a real third-party app store on the wrist or a handful of proprietary mini-apps.

Display
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) is marginally ahead, 9.8 to 9.6. A gap this small rarely decides a purchase on its own, though it counts if panel type, brightness, always-on behaviour and legibility in sunlight is your priority.
Build & Durability
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) is marginally ahead, 9.6 to 9.4. A gap this small rarely decides a purchase on its own, though it counts if case and glass materials, water and dust ratings, and how well it survives daily wear is your priority.
Value
The Apple Watch Ultra 3 (49mm, GPS + Cellular, Titanium) is marginally ahead, 6.8 to 6.6. A gap this small rarely decides a purchase on its own, though it counts if what you get for the money once LTE upcharges and subscriptions are counted in is your priority.
