I’ve had the chance to test both the Apple Watch Series 10 and the Garmin Venu 3. I wore both for weeks. Here is what stood out. Apple Watch Series 10 nails the smart stuff: smooth iPhone pairing, rich apps, calls and texts, and polished safety features. Garmin Venu 3 is stronger for health and training: deeper recovery insights, stress and sleep tracking that make sense, and battery that lasts for days. Both are excellent. Your pick comes down to what you value more, smart features or training and battery. Keep reading for clear results on battery life, health metrics, workout accuracy, design, and price.
The 30-Second Verdict
- iPhone user who lives in Messages, Spotify, and smart-home shortcuts? Apple Watch Series 10
- Runner, cyclist, triathlete or anyone who hates daily charging? Garmin Venu 3.
- Want both? Budget for a two-watch rotation (yes, people do this).

Design & Display
The Apple Watch Series 10 feels like the future on your wrist. The display is bigger and brighter than ever, with colors that really pop even outdoors. It’s incredibly sleek and customizable, I changed bands easily to suit work, workouts, and nights out. This is the thinnest model yet and feels great on my wrist, and you can clearly feel the difference.
The Garmin Venu 3, on the other hand, has that classic round design that people often prefer if they want their smartwatch to look more like a traditional watch. The display is big and gives a good overview of the user interface. The AMOLED screen is gorgeous, and I found it easy to read even in direct sunlight. It does feel a bit bulkier, but that adds to its sporty, rugged vibe.
Health & Fitness Tracking
When it comes to health tracking, the Apple Watch Series 10 is incredibly comprehensive. I loved the ECG, blood oxygen, and temperature features, and the sleep tracking has improved a lot. The new “vitals” app is a great addition where you can see if all of your vitals are within normal ranges. If anything is outside the norm, you’ll receive an alert.
But for pure fitness, Garmin is still king in my experience. The Venu 3’s GPS accuracy was spot-on during runs and bike rides. The recovery insights, advanced sleep coach, and detailed workout metrics gave me way more data to work with. If you’re serious about your training, the Venu 3 gives you tools the Apple Watch just doesn’t match natively.

Both watches are solid for fitness and health, but they each have their strengths. I like how the Garmin Venu 3 gives me built-in stress tracking, detailed sleep reports, and options like wheelchair-specific workouts and biofeedback meditation. The Apple Watch Series 10 shines with its extra sensors (like ECG and temperature) and tight integration with Apple’s ecosystem. I’ve also found that calorie estimates on the Apple Watch can be lower than what I see on other devices, so that’s something I keep in mind when tracking my activity.
HRV
Apple Watch Series 10 quietly samples your HRV (SDNN) whenever you’re still for a minute, whether you’re at your desk, stuck in traffic, or asleep, so you’ll see multiple dots on the Health graph throughout the day. The catch: Apple only stores the raw values; to turn those scattered numbers into a daily readiness score or recovery trend you’ll need to run a quick Mindfulness-Breathe test each morning and let a third-party app like Training Today or Gentler Streak crunch the data.
Garmin Venu 3, in contrast, ignores random daytime snapshots and instead measures HRV continuously while you sleep; after three weeks it establishes a personal baseline and then every morning delivers a single, color-coded HRV Status (Balanced / Unbalanced / Low) plus trend insight right on the watch face – no extra apps, no manual tests, just an immediate “train or recover” answer
Sleep Insights
Sleep insights are good on both watches, but I still miss having a dedicated and native “sleep score” on my Apple Watch. Garmin provides this together with a sleep coach, which is super nice. I also enjoy the morning report that Garmin offers, giving me a summary of my night. Apple Watch does have third party apps that can be used. Make sure to check out my top 5 health and fitness apps for Apple Watch:
Battery Life
No contest here. The Apple Watch Series 10 still needs daily charging, I could stretch it to about a day and a half if I turned off the always-on display, but not much more. The Garmin Venu 3 easily gave me over a week of use, even with regular GPS workouts and the display always on. It’s incredibly freeing not to think about charging every night. However, I feel the 80% quick charging in just 30 minutes for the Apple Watch Series 10 has made the battery life less of a pain compared to previous models.
Smart Features
Apple wins on smarts. The Series 10 integrates so smoothly with the iPhone, from answering calls to using Siri to control smart home devices. The gesture controls like double-tap were genuinely useful, and having access to a huge range of apps was great. It also really nice to have the GPS + Cellular model as you can use call and receive text even without your phone near by. This is something Garmin Venue 3 does not offer.
The Garmin Venu 3 does offer music storage, notifications, and basic assistant support when paired to your phone, but it doesn’t feel as polished on the smart features side. Garmin clearly focuses more on fitness than on creating an all-around mini smartphone on your wrist.
I also prefer the notifications on the Apple Watch over Garmin. On Garmin, all notifications look the same, which makes it harder to quickly see what they’re about. On the Apple Watch, the design is smoother, with different icons and colors for each app, so it’s easy to spot what’s important and what can wait.
Price
The pricing is pretty close. The Apple Watch Series 10 starts around $399 and can go higher depending on materials and whether you get cellular. The Garmin Venu 3 sits at around $450, though you can often find discounts. Both feel fairly priced for what they offer.

If you want a watch that’s focused on fitness, with better battery life and deeper workout insights, the Garmin Venu 3 is the clear choice.
Personally, I’ve found myself switching between the two depending on my priorities: Apple Watch when I want smarts and convenience, Garmin when I’m training hard or spending more time outdoors. However, if you wonder what I wear today, I have Apple Watch series 10 on my wrist.
