| Price | $409.99 | $699.99 |
| Release Year | 2026 | 2026 |
| Phone Compatibility | Android only, and heavily Samsung-favoured. Requires Android 13 or later with at least 1.5 GB RAM. It will NOT pair with an iPhone at all. On a non-Samsung Android phone you lose ECG and blood pressure (the Samsung Health Monitor app is Galaxy-phone only), the SmartThings camera-feed integration, the Camera Controller remote shutter, DND/bedtime sync and audio messages. | Android only.

| Claimed Battery Life (hrs) | 24 | 60✓ |
| What the Battery Claim Assumes | The 24 h here is a measured figure, not a Samsung claim: Samsung publishes no hours figure on the US Galaxy Watch9 page — only that the larger battery means 'less frequent charging'. GSMArena's review of the 40mm (390 mAh) got roughly 24 hours of normal use including a 3-hour GPS hike, and under 24 hours with the always-on display plus a 1.5-hour tracked workout. The 44mm reviewed here carries 445 mAh. | 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 (mm) | 44 | 47 |
| Display | Super AMOLED under sapphire crystal, up to 3000 nits | 1.52-inch Super AMOLED under sapphire crystal, up to 5000 nits — the brightest smartwatch display sold |

| Third-Party Apps | Google Play Store on the watch — a real Wear OS catalogue, though thinner than watchOS and with several Samsung-phone-gated first-party apps | Google Play Store on the watch, same Wear OS catalogue as the Galaxy Watch9 |
| Health Features Enabled in the US | ECG and irregular heart rhythm notifications are FDA-cleared; sleep apnea detection is FDA-cleared. Blood pressure began a phased US rollout on 31 March 2026 — but it is NOT FDA-cleared, it runs through the Samsung Health Monitor app, and it must be re-calibrated against a separate upper-arm cuff every 28 days. BIA body composition and skin temperature are wellness features, not cleared measurements. | 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 is required for core metrics. Samsung bundles trial subscriptions to third-party fitness apps that renew at full price. | No subscription for core metrics; bundled third-party fitness trials auto-renew at full price. |
| LTE Option | Separate SKU and separate ASIN: the LTE Galaxy Watch9 is a roughly $50 upcharge over Bluetooth at each size, plus a carrier line. | 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 | IP68 and 5 ATM (50 m), MIL-STD-810H | 10 ATM (100 m), IP69K, MIL-STD-810H, EN13319 dive certified to 40 m |
| Battery Replacement | Samsung does not sell a consumer battery-replacement service for Galaxy Watch; the case is sealed and the practical answer from service centres is a whole-unit swap. | No consumer battery-replacement programme; the titanium case is sealed. |

Category Scores
Battery Life
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) leads clearly here, 7.8 against 5.8 — a 2.0-point margin on real endurance between charges, judged against what the claim actually assumes rather than the headline number. If that is what you are buying for, the Samsung Galaxy Watch9 (44mm, Bluetooth, Aluminum) does not close the gap elsewhere.
Health Tracking
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) is marginally ahead, 8.8 to 8.6. A gap this small rarely decides a purchase on its own, though it counts if depth of heart, sleep and body metrics that are genuinely enabled and cleared for use in the US is your priority.
Fitness & GPS
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) leads clearly here, 9.0 against 8.4 — a 0.6-point margin on workout tracking, GPS accuracy, sport modes and training analysis. If that is what you are buying for, the Samsung Galaxy Watch9 (44mm, Bluetooth, Aluminum) does not close the gap elsewhere.
Ecosystem Freedom
The Samsung Galaxy Watch9 (44mm, Bluetooth, Aluminum) and Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) are level here, at 2.5/10 each. 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 is not what separates these two — look to the categories where the scores diverge.
App Ecosystem
The Samsung Galaxy Watch9 (44mm, Bluetooth, Aluminum) and Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) are level here, at 8.5/10 each. whether there is a real third-party app store on the wrist or a handful of proprietary mini-apps is not what separates these two — look to the categories where the scores diverge.
Display
The Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) is marginally ahead, 9.6 to 9.2. 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 Samsung Galaxy Watch Ultra2 (47mm, LTE, Titanium) leads clearly here, 9.4 against 8.0 — a 1.4-point margin on case and glass materials, water and dust ratings, and how well it survives daily wear.

Value
The Samsung Galaxy Watch9 (44mm, Bluetooth, Aluminum) is marginally ahead, 7.0 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.
