I purchased this as a replacement for my old Garmin Forerunner 305 that I used to train for tri’s and half marathons with. I went with this model for the versatility and application in damn near every adventure imaginable. I primarily use it to track my CrossFit workouts and running. It is sleek and has a tactical look, which appeals to the veteran in me. It measures time, distance, elevation, temperature, pressure, heart rate and respiratory rate. Has a digital compass, altimeter, storm alarm, barometer and can receive push notification from my phone. Every workout I do is logged to an app on my phone and then displayed on a website that allows me to view about 20-30 different parameters of my activity. And all of that is really just the beginning. Now, don’t get me wrong, I love this watch. I fu**ing love it. But there have been numerous issues with its performance. Let’s start simple: The storm alarm has alerted me to one storm since I’ve owned the watch. It has missed about a dozen. The one storm it actually alarmed on, the storm had already hit and was leaving. Not a great alarm in my eyes. Next: the push notifications and bluetooth connectivity absolutely suck. I was excited to have my texts and calls display on my watch, so I could determine if the inconvenience of retrieving my phone from my pocket was worth the effort. This feature only works about 40% of the time. It would lose the connectivity with my phone about six to seven times a day with no explainable reason. The phone would be in my pocket, and I would pull it out and see I had missed calls or messages, that my phone did not display. Alternatively, there would be alerts pending on my watch that were already cleared from my phone. The recent firmware update did not seem to alleviate this issue much at all, either. The action buttons are irritating, as I am constantly stopping and lapping my workouts mid routine from the button being depressed when I am doing a pushup, ring dip or handstand. I don’t really know of any way to solve this issue, other than put the action buttons during exercise on the left hand side of the watch so I don’t press them anymore. Or at least make the buttons user programmable, so I can do this, and a left handed wearer can do the opposite. Battery life is a complete joke. This was rated at 30days on "Time Only" mode. This meant to say, that when it is only used for telling time, the battery would last for a month. Doubtful. From the start, I keep the time, activity monitor, elevation monitor and push alerts active. For the first two charge cycles, it lasted like this for about 15-18 days before I was forced to recharge. Now, without the push alerts and elevation monitor, I am lucky to get 10 days out of a charge. I am currently on day six and the battery level show 21%. I thought it just needed calibration, so I ran the battery until the point of failure, with no change. I’m doing less with my watch and getting less result for it. Last gripe: the heart rate strap. This piece of garbage needs to be scrapped and redesigned, PRONTO. It comes as two separate pieces, an actual strap with sensors and the logic board and memory chip that snaps into the front of the strap. This itself is aggravating, since you can only buy replacements as the pair anyway. The strap is wearing out after a month, and I will be forced to purchase another strap with sensor chip to replace it. Waste of money and materials. The snap-in sensor is a horrible idea, because it denies a streamline and sleek profile for the sensor. You have a strap, and a button that protrudes from the chest like Iron Man. Not to mention, doing CrossFit, I have snagged the sensor and unsnapped it multiple times mid-activity, losing my heart rate coverage. The strap is flimsy and soft, and as soon as you put it on it rolls up into a string and cuts into your skin. It has actually proven painful in some cases. Now it’s just plain falling apart. Thankfully, I can pair my watch to any third party heart rate strap, which I will be researching and selecting soon. Suunto: Fix this pile of crap ASAP. And fix my battery and bluetooth connectivity as well.

This is the best backwoods, do everything, I love to be in the great outdoors watch I have ever used. I’ve owned every model of GPS watch from Suunto and Garmin, and this is my favorite. There are specific ones for triathlons, cycling, etc., but this one does it all. Plus the Sapphire model is nearly indestructible. You won’t regret it!

Great watch! Spent months searching and debating between garmin fenix2, polarv800 and suunto ambit 3 peak. Really glad I went with the ambit3 peak. I am a swimmer and starting mountain biking, so swim capabilities and cycling capabilities were most important. Needed heart rate and swim metrics WHILE swimming and the ambit 3 with the chest strap works great. Only problem is I hate using cheststraps when swimming in pools, since when one pushes off wall the cheststrap falls out of place, so ambit3 allows me to connect with miofuse wrist heart monitor with perfect connectivity while swimming (important to use in same wrist).
Form factor is great, however it is a bit bulky, but I have big wrist so i can fly it and use it as an everyday watch.
Battery life is great.
I am still learning how to use Movescount to its full capacity, but so far it allows me to record all data and view it properly.
