  • Familiarity: I've put it through the wringer

For the most part I've loved having this watch which I use for my 2 main fitness activities, running and split boarding.

The reason I've given it 2 stars and really wouldn't recommend this watch to anyone is that it's let down by synchronisation issues with movescount (the website that stores all your 'moves').

About 6 months ago there was a software update that meant I couldn't sync via bluetooth. Given I was overseas and didn't have my laptop to sync via cable this was really annoying. It was finally fixed a month later. Not good enough.

Right now (Early August '16), due to another software update I can't synch my watch - that is I can't transfer all of my moves out of the watch to movescount which is kinda the whole reason I have this stupid watch. I've been told by support that it will be fixed sometime "in the next month". WTF. How completely useless. Given the watch can only store a certain number of moves before it starts overwriting the oldest move, I'm really disappointed. The watch is basically useless to me right in the middle of the southern hemisphere ski touring season. The GPS function is (usually!) really handy when split boarding as it offers a navigation option. Because I can't sync, I can't add waypoints for my touring days.

The customer service is useless, the usual "We're very sorry" platitudes but very little information on how and/or when they are going to fix the problem.

When it works, it's great. You see see all kinds of useful info e.g. exactly where you went downloadable to google maps (or any other map software), total vertical, Heart rate (if you have HR strap) etc basically anything.

I'll be contacting backcountry.com for a refund as this product is unreliable.

Thanks for the review Richard! Super helpful to get this feedback out to the community.

Tough To Love Without It

  • Familiarity: I've used it several times

This review is copied over from my original which was left on the HR version, they are the same watch. I do recommend if you get the Ambit 3 Peak to get the HR band eventually as the major difference or positive about this watch versus others is the training feature which pretty much requires the use of the HR band.

I owned the Vector and Core for years. When I saw this come out I balked at the USB Charging feature and the need for GPS functionality in a watch. A buddy had one for a few years said it was great, I wanted to see what all the hype was about.

The first thing I noticed about the watch is its ability to communicate with your phone. I teach skiing and need to have my phone on me in case parents call or text but, pulling it out in front of someone is rude and my hands get cold. The watch would now display the texts and incoming calls. You cannot respond but, at least you can easily see whats going on without pulling out your phone. When its connected like this the battery drained quick. I had to charge every night. The major competitor, Fenix 3 does this a bit different, email me if you have questions regarding the differences.

The mapping function is the best part. It does not come with built in maps but, I don't really need them or have ever used them with an actual GPS. For most routes/trips you only need to upload a few way points at home to make sure you are on track. A screen map is so tough to read, if you need or want a map for your trip get a paper one. I'd been trying to get a climbing route here in SLC that is very tough to find the start. There are multiple ridges and they all look the same. Uploaded the way point and when I was at the right ridge the watch confirmed, success! The picture that is uploaded here is how Moves Count the app will spit out your map. On this particular route the clouds rolled in heavy and we had no idea if we actually skied the right route. The classic summit tree looked correct but, we still didnt know. Was nice to get home and confirm as well as get objective data on the climb.

The battery was my biggest fear about this watch. If its going to be longer than a 12 hour day I generally turn off the GPS and use the watch like I used the Core. Altimeter readings and pacing based on vertical elevation gain. Under 12 hours I run the GPS so I can look at all the data when I get home, have not had an issue yet. If I ever go on an expedition, no doubt Solar panels will be there to charge other electronics, and it does not take long for a Flip 10 from Goal Zero to charge this on the road.

I did not really need the Peak Ambit 3. I wanted it because I wanted to experience the best. I have not ever really used the training features. This might change, its nice to know they are there but, if you don't intend to use the training features get the Suunto Traverse. Please email me if you would like to discuss some of the differences with models. There are a lot out there and its a big investment, I can help with some of the homework!

Sweet GPS/Training Watch So Far

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: one size

I was stoked to get my Suunto Ambit3 Peak GPS Watch as I've gone with a T6 in the past and have loved the Suunto functionality and durability (have that T6 for 7 yrs now). Overall display is really clear and functionality takes a bit to get used to but considering what functions are use4d (GPS, Barometer, Compass, etc) the learning curve isn't bad. The wireles to iPhone app is a really nice touch and that same old durability is there as I've brush a few rocks and come out okay. Will write a more in depth review later, but solid so far.

So far so good

This watch came highly recommended from a group of very active friends and so far it has not disappointed. I have used it for running, snowshoeing and lap swimming in the pool. It has so many functions I have to admit I am still trying to figure them out. The online manual and videos have been great. I’m excited to get to know it better and take it to some fun places.

My New Best Friend

  • Familiarity: I've put it through the wringer

This is my first Suunto, and let me just begin by saying I do not think I will move to anything else. I had a entry level Garmin prior, which I thought was a great watch but it was lacking some more advanced features for hiking and running. Once the band broke I decided to take a stab at a Suunto. A buddy/co-worker had an older generation of the Ambit and he spoke very highly of it. After using it for route finding in the desert while canyoneering with him I could see why.

I am very happy with my decision. I have owned this for 6 months or so and am very pleased. I hike/run a lot of the same routes and the GPS on this watch is spot on to known mileages within a few 100th's. The altimeter is close enough to not really worry, especially on the ascent. Some routes tend to fair better than others, but I have never had a route be off by more than 50-100 feet.

The battery is solid, just for casual use I can go weeks without charging. During heavy periods of activity and GPS use I can usually get 3 days or so (all depends on how long the GPS is on).

For running this watch is amazing. I still have not used the HR monitor, but it is very easy to read while on the move and has too many features to list.

Lastly the one major advantage this watch has over the Garmin is it gains a signal extremely quick.

Still early but a real quality watch

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Be prepared when you get this to have an interesting experience with set up...no manual is included, you need to interface with the internet, initially I couldn't even find a manual online though there is great video help...that said a nearly 60 year old got this watch working on watch, computer/website and iPhone app without calling for help. It is a nice looking watch, and I love the notices that emails/texts/vmails are on my phone and from whom....

Best Sports Watch I've ever owned

  • Familiarity: I've used it several times
  • Fit: True to size

I have been a real Garmin fanatic. I've had nothing but Garmin watches for the last 8 years. Forerunner 305, 310xt, 910xt, and I bought a Garmin Virb elite action cam just because it was a Garmin not Go Pro.

I was getting ready to upgrade my 910xt, and have been doing a lot more trail running, hiking, skiing the last several years, so I was looking at some options.

I decided to purchase the Ambit 3Peak over the Garmin fenix 3. I cannot say anything about the fenix 3, but my Ambit 3Peak is the best of all the previous watches. Better GPS satellite acquisition, more accurate, really like fusing barometric pressure with GPS for altitude. I will say this, I love the watch, but it may not be for everyone. It seems to me to be more of a technical watch for outdoor sports, where altitude, heading may be paramount to speed and distance, but does just great for running.

Best Sports Watch I've ever owned

So I'm really torn on the Ambit3 Peak vs the Sport.
Mostly I intend to use it for splitboard mountaineering and training purposes: Trail running, cycling...
Will I really miss the features of the Peak if I cheap out??

Hi Reid,

I would splurge for the Peak version. It will give you longer battery life, better altimeter accuracy, as well as exclusive weather/barometric features.

Feel free to contact me with any other questions.




Doooo it Reid, Ben's a good guy.

Just give him a lil call.

Smoked on the Summit of Lone Pine Peak.

Got there 6 pitches after the sun went down.

We shivered in our bivies until moving sounded better than freezing, then used the route following capability of the Ambit 3 Peak to follow tracks I'd created in Google Earth to descend the back of the route and get back to the trail. Awesome watch. It's becoming an extension of my body.

Smoked on the Summit of Lone Pine Peak.

Benighted on The North Ridge of LPP!

Had an unexpected bivy on the summit of Lone Pine Peak in the California Sierra Nevada. You know that sense of dread that overtakes you when you realize you're going to have to climb 6 trad pitches in the dark by headlamp on terrain you've never been on? You know how that sense of dread turns into pure stoke after the first two pitches? Weird. Why is that? Anyway, I was wearing my Suunto Ambit 3 Peak the entire time and it recorded this. Pretty cool!

I'm still loving this watch.

On the way down we had to descend a chute, but there are multiple chutes, only one of which does not terminate in cliffs. Prior to heading up the mountain, I created tracks in Google Earth and loaded them into the watch so that I could follow them in the UNLIKELY event that we got...benighted.

I activated the route and followed it exactly. And it of course led us straight to the proper chute. Once down the chute, I activated my "ChuteBase2Trail" route and followed that meandering track that I had meticulously created to gain the least amount of elevation to get back to the trail. We followed it exactly, and arrived at the trail. The motto of the trip became "Always trust Google Earth". The Suunto Ambit is a very efficient tool that allows me to utilize GE in the BC. I love it.

Reliable and Perfect

I've used the Suunto Ambit3 Peak for 90 runs now through various mountain terrain. I use the Bluetooth feature to transfer the runs to MovesCount then on to Strava. I find the watch to be light but durable, easy to configure using the MovesCount app, and delightfully more reliable than the Strava iPhone app.


  • Familiarity: I've put it through the wringer

Not much to say beyond what's already been detailed here, but this is a great piece of gear for data nerds. I use it for running, mountaineering, and ski touring. The Movescount app works infinitely better than Garmin Connect and the watch itself is far more intuitive than any comparable Garmin product. As always, GPS watches suffer when you gain a ton of vertical in a very short linear distance (rock climbing), but outside of that, I've had no problems with this product.

Andrew, doesn't this model have a barometric altimeter? I have the old Ambit2 (with barometric altimeter), and I find that the barometric really outperforms GPS when in more vertical environments. However, having the GPS to set your starting elevation is really a great help (when traveling or dealing with pressure changes).

Inches of mercury?! Where's my club?...

Here's a shot of the Ambit3 Peak displaying atmospheric pressure in inches of mercury at 10k feet. I just now realized that you can mix and match system units on this watch, which is awesome! We all know that the kilopascal is the proper SI unit of atmospheric pressure and that "inches of mercury" is a throw back from caveman times that for some reason the United States of America is still using. Because the Pascal scale is metric, you just move a decimal, and barometers use hectopascals. Average Sea Level Pressure is 101.325 kPa, which barometers display as 1013.25 hPa (kilopascals vs. hectopascals...)

So, what I'm getting at, obviously, is that I've now set my Ambit3 peak to display barometric pressure in the globally-recognized and mathematically sound SI unit system of kPa (well, hPa...) which means I can sleep at night, again. (in my bed, not in my cave...)

If you're wondering why I still have it set to "feet" instead of "meters"...

I KNOW!! Thanks! I'm still trying to switch over.

Somebody who's smarter than me should write a Suunto app for this watch that displays elevations, distances and speeds in both imperical and metric units...would be a great learning tool.

However, as I mentioned earlier, you can cross-pollinate unit systems on the watch, so i'm showing feet and MPH (Imperial units of elevation and speed, respectively) while at the same time showing hPa. (metric unit of pressure)

So...why do barometers use hectopascals instead of kilopascals, you ask? Good question, and that's where the total hack that is the "millibar" comes into the story. Millibars are simply ridiculous! Hectopascals are a capitulation to stubborn early 20th century British meteorologists who invented the millibar out of thin air (pardon the pun) to be exactly analogous to the Pascal.

For some reason... :|

1 bar is exactly the same as 100,000 pascals.

So 1 millibar is exactly the same as 1 hectopascal.

Or rather, 1 hectopascal is exactly the same as 1 millibar...

Everything you never wanted to know about atmospheric pressure measurement.

Don't even get me started on PSI.
