Garmin Venu 3S Watch
Our Review
The Garmin Venu 3S is our top pick for anyone who wants a smartwatch that goes beyond notifications. Its AMOLED display is gorgeous, the health tracking suite covers everything from sleep to stress to Body Battery energy levels, and the 10-day battery life puts most competitors to shame. But what distinguishes it from Fitbit and Apple Watch is the depth of data. Garmin's Firstbeat Analytics engine processes HRV, respiration, and movement into genuinely actionable metrics — not just step counts, but VO2 max trends, recovery time recommendations, and morning readiness scores that actually calibrate with how you feel. For athletes and serious health trackers, the Venu 3S provides intelligence that both the Apple Watch and Fitbit struggle to match.
Health Metrics & Accuracy
The Garmin Venu 3 is the most health-focused watch Garmin makes without stepping into the medical device category. Its Body Battery metric — a 0-100 score based on HRV, sleep, stress, and activity — is one of the most actionable health tools in any consumer wearable. When it reads 20 in the morning, you're genuinely recovering; at 80+, your body is primed for high-intensity training. The Sleep Coach and suggested rest recommendations have measurable face validity for athletes managing training load.
Accuracy is Garmin's competitive advantage. The Elevate V4 optical heart rate sensor tracks well during steady-state cardio and resting HR. The wrist-based pulse oximetry and respiration rate are less accurate than medical devices but useful for trend tracking. Built-in GPS (with multi-band option on Venu 3S) provides distance and route accuracy significantly better than optical GPS alone — important if running or cycling data precision matters to you.
Who It's For
✓ Great For
Serious fitness enthusiasts wanting deep health analytics, athletes who want GPS accuracy plus daily health monitoring, Android users wanting the full smartwatch experience.
✗ Not Ideal For
iPhone users who want tight iOS integration (Apple Watch does this better), casual users who don't engage with health metrics, those prioritizing a slim, fashion-forward design over functionality.
What We Like
- Incredible battery life
- Advanced health metrics
- Built-in GPS
What We Don't
- Pricey
- Garmin UI learning curve
Our Verdict
The Garmin Venu 3S is the smartwatch we recommend to anyone serious about health tracking. Its sensor suite rivals dedicated medical devices, and the 10-day battery means you actually wear it consistently enough to get useful data. The AMOLED display is vibrant in any light, and the Body Battery feature alone justifies the price.
How We Tested This
We wore the Venu 3S for 21 consecutive days, tracking sleep, workouts (running, cycling, strength training), and all-day health metrics. GPS accuracy was tested against a dedicated Garmin Edge cycling computer. Heart rate was compared against a chest strap during HIIT sessions.
Who It's For
Fitness enthusiasts who want deep health metrics without sacrificing smartwatch functionality. Runners, cyclists, and gym-goers who need reliable GPS and workout tracking.
Who It's Not For
Casual users who just want notifications — an Apple Watch SE costs less and handles basics better. If you're deep in the Apple ecosystem, the Garmin app experience may feel disconnected.

If budget is tight, the Oura Ring Gen 3 offers superior sleep tracking at a lower entry price, though it lacks GPS and a display.
