Battery life is a standout across reviews, with multi-day real-world endurance and especially strong results on larger or solar variants.
Battery life is mixed. Some reviewers easily reached well beyond a full day, but others still frame it as a daily-charge watch or a shorter-lasting option than pricier models.

Broader health tracking is well regarded overall, though reviewers focused more on usefulness than exhaustive lab-style validation.
Side-by-side testing described the SE 3 as producing similar results to higher-end Apple Watches and matching the Series 11 closely for sleep, heart rate, and other health data.
Heart-rate accuracy is generally strong, but fast intervals and some sport-specific edge cases still trip it up.
Multiple reviewers found heart rate tracking reliable and accurate, with results close to reference devices and enough consistency for everyday workouts and health monitoring.
LTE remains the biggest missing hardware feature, and reviewers repeatedly flagged its absence.
Cellular connectivity gets a meaningful boost from 5G support, with reviewers describing it as useful for leaving the phone behind and handling calls, messages, or downloads on the move.
Premium materials such as titanium, steel, and sapphire reinforce the high-end feel, even if they can still show wear.
Materials are good for the price, centering on aluminum and improved Ion-X glass rather than the more premium finishes found higher in the lineup.
Garmin’s menus are more organized than before, but reviewers still found navigation uneven and occasionally cumbersome.
Menu navigation is easy and quick, with reviews noting snappy movement through apps and an interface that is simple to learn.
Music controls are available during activities, though one reviewer disliked being stuck with the extra music page.

The design was seen as rugged and premium, though still undeniably large and utilitarian.
Design is the main visual compromise: some reviewers still like the look, but many describe it as dated because of the thicker bezels and older chassis.
Third-party support exists through Connect IQ, but reviewers still see Garmin as limited compared with fuller smartwatch platforms.
Third-party app support is one of the SE 3’s biggest differentiators at this price, thanks to broad App Store access and a large software selection.
Touch interaction is mostly strong, especially on AMOLED, and new touch-unlock behavior improves usability in workouts.
Touch interaction is responsive and dependable, with one review saying the touch screen and gesture controls consistently work as expected.
The redesigned UI is more colorful and modern, but opinions remain mixed because it can still overwhelm or slow down common actions.
The overall interface is seen as fluid, cohesive, and well thought out, making everyday tasks straightforward even on the smaller display.
