Battery life is a major strength, with most reviewers seeing multi-week endurance, though heavier workout or connected-GPS use can shorten it.
Battery life is a clear step up for an Apple Watch, typically landing around two to three days or roughly 45 to 49 hours, but it still trails endurance-focused sports watches.

Blood oxygen support is present and repeatedly called out as part of the Ultra 3’s health feature set.
Bluetooth-linked features work, but connectivity is not flawless. One review mentioned the app losing connection during workouts.

Fit can be excellent once adjusted, but metal-band sizing is not foolproof and may take some patience.
Fit is more divisive than comfort, with smaller-wrist users reporting that the case can feel oversized or require readjustment.
Fitness tracking is generally credible for everyday use, but reviewers frame the Nova as stronger for broad health tracking than for detailed sport analysis.
Across general fitness use, reviewers described the tracking as accurate and among the best all-round smartwatch performers.
Connected GPS can track workouts accurately when paired with a phone, but one review also reported gaps after the app lost connection to the watch.

Reviewers described the Ultra 3 as an excellent health tracker with strong overall health monitoring.
Heart-rate tracking is a clear strength, with one reviewer saying average heart rate deviated by only one point and another calling the heart-rate results accurate against other smartwatches.

5G and cellular support are meaningful upgrades, with reviewers noting standard 5G inclusion and stronger reception in weak-signal areas.
Stainless steel, sapphire, and other premium materials are repeated selling points across reviews.

Safety is one of the Ultra 3’s headline strengths, centered on satellite SOS and other off-grid emergency tools.
Size flexibility is limited on the main Nova, with one review specifically pointing out that it comes in only one 42mm size.
Size flexibility is poor because the Ultra 3 is sold in only one large 49mm case.
Sleep tracking is useful but inconsistent. Some reviewers found it accurate, while others saw missed sleep periods or questioned the precision of the sleep readings.
Sleep tracking itself was viewed positively, with reviewers saying Apple handles the core sleep detection well.
Notifications work best as simple alerts. Some reviewers were satisfied with them, but others found the scrolling text too limited or too fast to be truly useful.

Siri performance was described as responsive and useful.
The analog face and lume are well liked, and reviewers describe the watch face itself as premium.
Exclusive faces like Waypoint and Modular Ultra were singled out as attractive and genuinely appealing.
