Galaxy Watch Ultra2

About Galaxy Watch Ultra2

The Galaxy Watch Ultra2 is the rugged end of Samsung's smartwatch range. Samsung announced it at Galaxy Unpacked in London on 22 July 2026 and put it on sale on 7 August 2026. It sits above the Galaxy Watch9 and is built for training that runs for hours and for conditions that would trouble an ordinary watch. It comes in one case size only, 47 mm, in titanium. The two changes Samsung leads on are an 800 mAh battery, up from 590 mAh in the first Galaxy Watch Ultra, and a display rated at 5,000 nits so it stays readable in direct sun. Samsung also states a body 12 percent slimmer than the model it replaces, at 10.7 mm.

Where the Watch Ultra2 sits in the Galaxy Watch range

Samsung runs two watch lines. The Galaxy Watch9 comes in 40 mm and 44 mm aluminium cases with 3,000 nit displays and smaller batteries, and it is the one aimed at everyday wear. The Watch Ultra2 comes in a single 47 mm titanium case with sapphire crystal over the display, and it is the one aimed at people who put a watch through something.

Samsung says this is the first Galaxy Watch to run the Qualcomm Snapdragon Wear Elite Platform. It is rated IP69K and 10 ATM, and it is the first Galaxy Watch to carry EN13319, the European standard for diving equipment. Samsung commits to five years of software and security updates. The gap between the two lines is not small: TechRepublic puts the Ultra2 at a premium of about 320 US dollars over the Watch9 at launch, which is the number to hold in mind while reading the rest of this.

Who this line is for

Three groups get their money back on this watch. The first is trail runners. Samsung built a Trail Run mode that tracks elevation, climbing progress and the impact of terrain, and adds a Nutrition Alert that prompts for fluid based on an estimate of sweat loss.

The second is divers. The watch records depth, dive time and water temperature, and tracks ascent and descent speed against safe limits. Read the caveat in the next section before buying on this basis.

The third, and probably the largest, is anyone who is simply away from a charger for days at a time. That is the plainest case for the Ultra2 over the Watch9, and it does not require you to run or dive at all.

What the larger battery actually changes

The 800 mAh cell is a 35 percent increase on the first Galaxy Watch Ultra, and Samsung fitted it while making the case thinner, which is the part worth noting.

Samsung's own claim is up to 60 hours of use, as reported by TechRepublic. Wareable, testing it with automatic brightness, continuous heart rate, sleep tracking and 90 to 120 minutes of daily exercise, measured about four days. Either figure moves the watch out of the nightly charge habit, and that is the practical change. A watch you charge twice a week is a watch you can wear to sleep without planning around it, which is what makes the sleep and recovery tracking useful rather than intermittent.

One caution on the diving side. The dedicated diving application Samsung is building with Mares, which is where the decompression guidance lives, is a separate paid product due later in 2026. The watch on its own is not a replacement for a dive computer today.

What to weigh against its nearest rivals

Wareable's main criticism is the input method. There is no rotating bezel and no digital crown, so moving through widget tiles on a bare touchscreen while running hard is awkward. The same review found heart rate readings within half a beat per minute of a chest strap in general use, but noted the optical sensor struggles during resistance training. Some health features also require a Samsung phone rather than any Android phone, so check that against the phone you actually carry.

Against the Apple Watch Ultra, Samsung undercuts on price, but the comparison rarely gets that far: one needs an iPhone and the other does not, so the phone in your pocket usually settles it. Against Garmin's endurance watches, the trade is clearer. Garmin goes considerably longer between charges and costs more; the Samsung is a smartwatch first that happens to last a long time.

Who should buy something else

If your exercise is a treadmill and a step count, buy the Galaxy Watch9. It shares the health features that matter and costs far less, and you will not use the diving certification or the trail metrics.

If you carry an iPhone, buy an Apple Watch. This line is built around Android and some of its features narrow further to Samsung phones.

If you want a watch that runs for a week or more on expeditions, look at Garmin instead. Four days is good for a Wear OS watch and short by the standards of a dedicated endurance brand.

If you have small wrists or you prefer a physical rotating bezel, this is not the watch. Samsung sells one case size, 47 mm, and there is no bezel or crown to turn.

And if you need a working dive computer now, wait. The certification is real but the diving application is a paid extra that had not shipped at launch.

Sizes, colours and availability

The Watch Ultra2 comes in a 47 mm titanium case, in Titanium Silver and Titanium Gray. Samsung states a case weight of 61.5 g and a thickness of 10.7 mm.

Inside are 2 GB of memory and 64 GB of storage, running One UI 9 Watch on Wear OS. Connectivity covers LTE, Bluetooth 6.0, dual band Wi-Fi, NFC and dual frequency L1 and L5 GPS. It requires an Android phone running version 13 or newer.

Pricing starts at 699 US dollars. Pre-orders opened on 22 July 2026 and general availability began on 7 August 2026. Prices and colour availability vary by market and move over the life of a line, so treat these as the launch position and check Samsung's own store for what is current where you are.
