Display quality is excellent, with reviewers repeatedly calling the AMOLED screen vivid, colorful, and easy to read.
Reviews point to strong durability through real-world wear and formal ruggedness claims.
Durability looks solid for daily wear and scratch resistance in several reviews, but not everyone found it especially rugged for rougher use.
One review explicitly states that ECG functionality is missing.
ECG support is mixed across reviews: some describe the feature working or being available, while others note launch or regional limitations.
Fit is mixed-positive: the large case may take getting used to, but it does not feel especially chunky on wrist.

Smartwatch features are well-rounded for a Garmin, covering calls, music, payments, notifications, and voice assistant access, even if rivals still do more.
Software smoothness has improved, but lag remains a recurring complaint.
Software smoothness is strong, with reviewers noting responsive touch input, fluid switching, and little noticeable lag.
Step tracking appears solid for everyday use, though reviews spend less time validating it in depth than heart rate or GPS.
Stress is tracked through the resources system, which estimates energy levels using stress and recovery inputs.
Stress tracking and related HRV-based context are seen as useful, with some reviewers finding the watch's stress feedback surprisingly accurate.
Reviewers consistently like the styling, describing it as minimal, rugged, or well-designed.
Style is a strength for Garmin here, with repeated praise for the refined look and easy transition from workouts to everyday wear.

Watch face selection is strong, offering classy, information-dense, and live options with plenty of room for personalization.
Water resistance is solid for swimming and snorkelling use, though not pitched as a full diving watch.
Water resistance is confidently presented for swimming, showers, and daily exposure thanks to the 5ATM/50-meter rating.
The watch offers wellness-oriented feedback such as VO2 max, fitness age, and training or recovery guidance.
Wellness insights are a major appeal, with the watch translating sleep, activity, stress, and recovery data into practical daily guidance.
