9 Peak and Peak Pro Sports GPS Watch for Demanding, Performance Driven Athletes and Adventurers

Great smartwatch for the last 2 months. Battery life ridiculously long - over a week no problem. Tracks steps, workouts and tennis scores. I can check my heart rate, blood o2 and sleep. Legible and easy to use. No problem pairing with my iPhone. I’m not much of a runner so I haven’t used it for that yet. I think it’s great looking in all black and sized smaller than many dive watches. Very comfortable to wear. My only knock is the strap which can come undone relatively easily. I added a black silicon strap stay and problem solved. For the price it was a no brainer and worth it. I don’t need the latest and greatest, this watch checked all my boxes.

The watch is great and reliable! As long as you can use it anywhere even sleep.

...and this one is my favorite. I'll keep it short, but I have used a Fit Bit Versa, Garmin VivoActive 3, Galaxy Watch 4 and 5, Pixel Watch (1), Apple Watch (SE), and finally, the Suunto 9 Peak Pro. And that's where I'll stay for awhile. For reference: Pixel is my favorite smartwatch variant and this is my favorite sports watch variant (by far). I wanted a watch with a MIP display, good battery life, GPS, and notifications + quick reply. There's all sorts of information about the features, GPS, etc... but I'll throw out there that the notification system is very good, you can customize which apps can send notifications. And I can quick reply on Signal (I don't need to on other apps so I haven't tried). Plus, I really like the Suunto app feed, and how easy it is to share the workouts and scroll through your history. Though, I share workouts back and forth with someone with a Polar watch and it's quite similar. But I like it better than FitBit, weirdly enough. Exercise context: I run, walk, and hike for 90% of my exercises. It's not 100% accurate of course, and heartrate can be tricky sometimes, but it definitely does these activities very well. When I do stairmaster, for some reason, it can't always get the heartrate right, I'm not sure why. It usually maxes out at 120 even if I'm 40 mins in and dying LOL. I'm sticking with Suunto for the near future, they've won me over. I upgrade tech pretty frequently, but I don't see myself wanting a watch upgrade for awhile unless there's something really tempting with a MIP screen, but my next watch will almost certainly be a Suunto either way.

I wanted a fitness watch to track heart rate accurately and send me high heart rate alerts. While the watch is able to do this, it was extraordinarily difficult to set up and once done, it triggers so many other sound alarms as to render the feature useless. So far, I have been unsuccessful in finding out what these extra alarms are for and how to turn them off. The watch does not measure sleep as other watches do. That is, if you get up in the middle of the night and then go back to sleep, the watch will not recognize the second sleep and there is absolutely NO way to alter your total sleep time. After receiving the latest software update, the watch has developed a habit of stopping heart rate measurement at random times. The solution is to turn off the watch and turn it back on, but in my case I need 24h data. This is no longer possible. Also, after the update, you can't change the ridiculous, hard to read watch face unless you pay a subscription. I'll try to sell it. I think the problem is that I need a general health tracker and not a cycling lap counter, which seems to be what this watch is for.

Wanted a smart watch that wasn't Apple or Google. I mainly use the heart rate and step counter functions, though it has a ton of other functionality, including typical smart watch stuff as well as automatic GPS mapping of your walks, rides, hikes, etc. Enjoying it so far. Good battery life.

I have mixed feelings about my purchase. I swim with this watch. Easy to read while splashing about, but I got two wildly different readings on two swims of equal distance. After swimming 2300m I burned 172 calories, and had a average heart rate of 72bpm. Next swim, same distance, 670 calories expended and average hr of 115. At least it counts laps for me. I'll keep swimming, but not rely on any of the physiological metrics it displays. At this price I guess it's good enough for the weekend athlete. Good enough user interface. 9/29/2025 The power percentage went from 100% to 20% in 5 hours. Not acceptable, I'll be returning watch.

Bought this as a replacement for my Suunto 9, which was beginning to feel a bit basic after 6 years of use. i was thinking of getting a Garmin but was put off by the price, when the 9 Peak Pro was approximately 1/4 to 1/3 of the Garmin cost. It interfaced with the Suunto app easily and I kept the data on the app from my old watch too. On first use - the battery lasted about a week from full charge to 20%, with doing approximately 3-5 hours of GPS monitored exercises, much better than my old watch. The step counter is better now not adding steps when I am driving! The oxygen sensor was hard to get going until I kept my hand still. Even though the initial measurements showed low readings which if real would have meant being hospitalized. I now include oxygen measurement during sleep and the maximum oxygen levels taken are similar to finger type meters. I mainly mountain bike, hike, do yoga and do open water swimming - all of which are covered. After 2 weeks I feel very satisfied.

I bought the watch about 2 weeks ago. I wanted to upgrade from my Suunto Ambit3 which I've had for over 10 years. Peak 9 is way lighter in comparison and offers more functions. Its basically like the galaxy watches without the ability to call or text from which I have no use for. I love the fact that Suunto is far more accurate when trying to maintain a pace with running or hiking than any other watch I've own.
