Samsung Galaxy Watch Ultra emerges as Wear OS leader despite Apple Watch similarities

When Samsung unveiled the Galaxy Watch Ultra, the tech world immediately drew comparisons to Apple's rugged wearable. The design looked borrowed—a round face wrapped in a protective casing that echoed the squared-off aesthetic of Apple's offering. But after two weeks of daily wear, the story becomes more nuanced. Samsung didn't simply copy; it borrowed selectively and built something distinct around those borrowed elements, targeting a specific user: the person who actually goes outside and does things.

The watch itself is a solid piece of engineering. The titanium casing feels premium, and the squircle design—neither fully round nor square—houses protective cushions around the edges that serve a real purpose. This isn't styling for its own sake. Samsung put the Galaxy Watch Ultra through rigorous testing: high and low temperatures, altitude changes, humidity, salt fog, dust, vibration, and drops. It earned MIL-STD-810H certification, the kind of durability rating that matters if you're mountain biking and actually fall off your bike. The display reaches 3,000 nits of brightness, which means you can actually read it in direct sunlight without squinting, a practical advantage for anyone spending time outdoors.

Three buttons line the right side of the watch. Two are familiar—Home and Back—but the middle button is new and customizable. By default it launches the workout menu, though you can reassign it to open a stopwatch, flashlight, or water lock. The limitation here is real: Samsung doesn't allow you to map it to Samsung Wallet or Google Wallet, which feels like an oversight for a premium device. The band connector changed too, incompatible with older Galaxy Watch bands, making it tougher to swap straps. It's a trade-off for a more seamless look, but it's a trade-off nonetheless.

The real story, though, lives in the fitness tracking. Samsung equipped the Ultra with triple the number of LEDs compared to previous models, which translates to measurably better accuracy during intense workouts. When worn side-by-side with an Apple Watch Ultra during exercise, the heart rate readings came back nearly identical—a significant achievement, since Apple has long owned the accuracy game. The addition of dual-band GPS is another meaningful upgrade, particularly for runners, cyclists, and hikers who need precise route tracking. The new BioActive Sensor underneath the watch does the heavy lifting here, measuring everything with noticeably improved precision.

The software running on the Galaxy Watch Ultra is Wear OS 5, and while the visual differences from Wear OS 4 are subtle, the health features are substantial. Samsung brought Galaxy AI to its wearables in the form of Health Assist, which analyzes your patterns and offers wellness suggestions—nothing invasive, just practical nudges about activity, sleep, and calorie intake. The Energy Score is new this year, a daily readiness metric calculated from sleep, activity, and heart rate data. It's the kind of feature Garmin and WHOOP have offered for years, but now it's here without requiring a subscription. There's also an FDA-authorized Sleep Apnea detection feature that works by analyzing two nights of snug-wrist wear.

Battery life sits in the two-to-three-day range with the always-on display enabled, which Samsung claims is 48 to 60 hours. Turn off the always-on display and you can stretch past three days, though not quite to four. Power Saving Mode pushes it well beyond 100 hours. The 590mAh battery is identical to what Samsung used in the Galaxy Watch 6 Classic, which is disappointing given the larger 47-millimeter case—you'd expect more capacity. Charging takes about an hour, but here's the catch: the new BioActive Sensor required Samsung to relocate the charging mechanism, so older Galaxy Watch chargers won't work, and reverse wireless charging from your phone is no longer possible.

The display itself is a 1.5-inch AMOLED panel at 480 by 480 pixels, the same size as the smaller 44-millimeter Galaxy Watch 7. In direct sunlight, it's bright enough to read without strain. The colors pop the way you'd expect from Samsung's AMOLED technology. You won't watch videos on it, but for checking complications—steps, calories burned, active minutes, weather—it does the job cleanly.

So who should actually buy this? If you're a casual smartwatch user, probably not. The Galaxy Watch 6 Classic costs less, has the same display size, the same battery capacity, and includes a rotating bezel that many people prefer. The meaningful upgrades—the BioActive Sensor, the MIL-STD-810H certification, the brighter screen—matter most to people who push their watches hard: hikers, runners, cyclists, anyone who needs durability and precision in the field. For everyone else, the Classic remains the better value. But for the person who actually uses their watch as a tool rather than an accessory, the Galaxy Watch Ultra makes a compelling case.
