An essential tool for mountaineers, backcountry skiers, and wilderness travelers. A fun tool for everyone else.

The weather was clear for days as your expedition ascended 10,000 feet, but then the barometric pressure started to change and your Storm Alarm went off. Thanks to the Suunto Core Altimeter Watch, you set up your high-altitude camp ahead of the big storm and are in your sleeping bag sipping hot cocoa before it hits. Bravo.

  • Highly sophisticated altimeter provides detailed data on your current elevation and elevation change over time—usable up to 29.500 feet
  • Seven-day altitude log and keeps track of your elevation gained and lost for you—so you can focus on the climb at hand
  • Keep an eye on approaching storms with an innovative motion-sensing barometric altimeter with seven-day memory and Storm Alarm feature
  • Additional features include timekeeping, date, chronograph, alarm functions, and underwater depth measurement to 30 meters.
  • Improved interface over previous models for a more user-friendly design
  • Parlez-vous français? Kannst du Deutsch? Habla Español? Yo, you speak English? The Suunto Core Altimeter Watch can answer oui, ja, sí, and yup
  • Slim profile, stylish design, and comfortable strap means you’ll probably want to take it to business meetings and out to dinner with your spouse too

A little pricy, but a great tool

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

I use this thing for hiking, fishing, hunting, anything outdoors related. I was a little hesitant to buy at first after reading some of the negative reviews, but I'm glad I took the chance. Its a great watch. The altimeter is pretty accurate as long as you follow the instructions. I would purchase it again if I lost it.

It's About Time

  • Familiarity: I've put it through the wringer
  • Fit: Runs large

I've searched far and wide for a reliable watch for outdoor activity. The Suunto Core is a reasonably priced wrist top computer that you can take with you on any excursion and trust that it will work. After five years of putting it to the test, my Core keeps on ticking. I like the altimeter feature, although it requires frequent calibration to be accurate within 200 vertical feet. The compass also seems to be accurate to within a few degrees (make sure you set the correct declination). My favorite part is the huge display. Even on a small wrist, it looks and wears fine. Sometimes you don't have the ability to stare at small numbers while in action, so the large font read out is much appreciated.

Great alpine watch.

  • Familiarity: I've put it through the wringer

I love my Suunto Core. It never leaves my wrist. I like how the face of the watch is large, which makes it easy to see the variety of features this watch offers. It's definitely worth the coin.

The only bummer about this watch is that the compass seems a bit iffy. I've set my declination, spun the watch around to reset the directions, yet when I compare the direction to my brunton, its off by 5-15 degrees. Hence the 4 stars instead of 5.

But weren't due to the obvious inclement weather.

8.5k feet on the Kahiltna. Since we couldn't see more than a rope-length, i was obsessively checking my Suunto CORE altimeter.
Kahiltna Base Camp is SOMEwhere out there...around 7100 feet or so...

And aptly named...

A favorite quote comes to mind.

"It was cold as hell...mitts and everything was all ice."
-Billy Taylor from the Sourdough Expedition...Denali, April 3rd, 1910...

The watch, of course, survived. This and many other similar experiences. I lost it somewhere on Mont Blanc a short time later.
But I like the watch so much, one of the first things I did when I got back to Chamonix was to buy another one.
After drinking a beer, of course...

Is there a difference in features between the discontinued colors models and the newer models?

Responded on

Hey There,
The only difference between the disc. model and this years is cosmetic. The functionality and features remained the same. If you have any other questions about this watch or other gear please give me a call at 1-800-409-4502 ext 4446 or email at gconner@backcountry.com

Fun and function

  • Familiarity: I've put it through the wringer

Bought this sucker for a 250+ mile hike on the Colorado Trail. This was a last minute-am-I-sure-I-want-one-of-these? purchases and I couldn't be happier having bought this watch. The features are excellent and intuitive; I read the manual once and figured out most of it on the trail. It survived multiple weeks of abuse and is looking darn good. My only criticism would be that the functions to set the altimeter reference point are a bit buried, but after a few times you'll zip through the menus without an issue. I"m stoked to take in BC skiing this season.

Man. I apologize. I can't stop uploading photos of my Suunto CORE. This is my 5th and probably won't be my last. I figured Mount Whitney Needed some representation.
STILL a great watch and I still love it. I have a fancy GPS watch now, and it's awesome, but the simplicity of the CORE still keeps it on my wrist.
It's as easy as ABC. (<-- see what I did there?...)

OK, I don't know why, but I dig this picture so much I have copied the idea it for my own personal gain. I can't quite get the same effect with my iPhone, but I'm still achieving fame that I never thought possible. If I see any fortune, you get half. Heck, you can have it all. Oh, and ABC - yeah, nice!

I love checking the altitude (probably too often) during both ascent and descent. Great tool.

Super Bummed

  • Gender: Male

Bought this watch in Nov '13 and 6 mos. later the screen started to leak and it no longer worked. Returned it to Suunto and was informed today that it is not covered by their warranty. Not about the money, but have spent (wasted) a lot of time on this and am really disappointed. Their customer service is a disaster - Be careful.

Bro, I have the spartan and Core, my spartan is foggin up '3months in' what excuse did they use as to why it wasn't covered????

Responded on

Interested in your warranty experience. Please provide details.

Time will tell...

Worn this daily for a year, at home or on the trail . Accurate measurements and looks cool.

It is pretty beaten up and I am worried in one more year it maybe completely finished

I'm looking to use this watch for backcountry skiing and summer backpacking. What is the difference between the core and the spartan? Any pros/cons of either?

Careful with DEET

  • Familiarity: I've put it through the wringer
  • Fit: True to size

FWIW... I've had my core for a while.

When I was in Tanzania (I toss that in so you will think I'm cooler than I actually am) I was regularly applying DEET, and I'm sad to say that it ate away at the watch in a surprising way.

I've always been aware that DEET eats plastic, but honestly I didn't expect the Core to be susceptible.

That said, my now pretty wildly deformed watch makes me look a lot tougher than I actually am!

Also note: be careful with replacement bands, especially if you want to replace the original awesome black stretchy band... that one is called "elastomer" and I found out too late.

Core Vs Ambit2 : For $300 less one could purchase the Core. Is there any defining factor that would push one to buy the Ambit (Ambit2 Sapphire) over the Core?

Responded on

Yup: the Ambit is a GPS watch, but the Core isn't. That's the "big" difference between the two.

Best Answer Responded on


The big difference between these two watches is the GPS, but that GPS does quite a lot for you. Suunto bills the Core as being for "explorers" while the Ambit 2 is for "athletes and explorers." The GPS on the Ambit 2 gives you a more precise altimeter by combining readings from GPS and barometric pressure. The GPS further enables you to track your ground speed, minutes per mile, and with the new upgrade that was just released, cadence as well. The Ambit 2 also has the option of pairing with a variety of accessories including a heart rate monitor. Also, while both watches are very well constructed, I think the Ambit 2 is the more durable, especially in the sapphire edition.

My advice is to really examine what you intend to use this watch for. If you are looking for a solid ABC watch for backcountry use, the Suunto Core will get everything you need. But if you want a watch that can also track and chart you training over time as you prepare for you next triathlon or ultra, then I think the Ambit 2 is worth the extra money.

Rock n Roll. New best friend!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Straight out of the box onto the wrist. I hit the mountain for some hike and fly paragliding, from the one and only mount doom (Mt. Ngauruhoe, New Zealand).
Epic features. Altimeter Accuracy to a T!
From this to mountain biking Whakarewarewa in Rotorua...to trekking the amazing spots around...flying light cessnas in the Marlborough Sounds...the logging of trips and reviewing, altimeter referencing and safety of compass navigation. I love this device. It has just such a simply smooth, but sexy look... coupled with a plethora of functionality. Easy to operate.
Fully Satisfied. Completely recommend for any outdoors enthusiast.
