A versatile navigation instrument to the core.

Whether you're measuring total elevation gain, navigating wild landscapes by compass, or using various barometer functions to forecast the weather, the Sunnto Core Crush Altimeter Watch is the only device you'll need. A depth meter records how deep you had to dive for that Caribbean conch shell, and the Storm Alarm notifies you if there is a sudden drop in pressure, which is a potential indicator for worsening weather. Oh yeah, almost forgot to mention that it can tell time, too.

  • Altimeter measures changes in elevation between 1600 and 29500 feet
  • Altimeter log recorder stores movements in altitude between designated start and stop times, allowing you to know how much you climbed, the duration of each section of the route, and the average ascent and descent speeds
  • Barometer measures sea-level pressure every 30 minutes and records a 24-hour history
  • Weather Trend Indicator utilizes seven days of weather history to help determine upcoming weather conditions
  • Storm Alarm notifies you if there is a sudden drop in pressure, a potential indicator of worsening weather
  • Watch switches automatically between altimeter and barometer—altimeter when you're climbing and barometer when you stop to take a rest, providing more a more accurate interpretation of changes in pressure
  • Digital compass can be set to track a certain bearing using the one-touch function or the traditional rotating bezel
  • Declination function corrects the difference between magnetic north and true north
  • Depth meter provides information regarding current and maximum depth while snorkeling (water resistance rated to 30 meters)
  • Multiple watch, date, and alarm functions with dual time and a countdown timer ensure you're always on time
  • Sunset/sunrise times for over 400 worldwide destinations are ideal for globe-trotting travelers
  • Digital thermometer provides accurate temperature readings
  • Electro-luminescent display allows you to read the watch at night
  • Menu-based user interface can be changed to read in English, German, French, or Spanish
  • Button lock prevents accidental setting adjustments
  • Runs on a CR2032 user-replaceable battery

Great watch for the price

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

I've used this watch a few times on shorter/ non-technical hikes (Adams/Hood/Muir). I wear a watch %20 of the time, so putting this on didn't feel out of place, it's very comfortable and I like the way it looks.
-Altimeter has been very accurate
-Large display makes it easy to read
-Buttons spaced far enough apart it's usable when wearing gloves
-Easy interface to learn

-Buttons are positioned on the left and right side of face, like most watches which means when climbing, or wrenching your hand backwards, you hit at least one button. I think buttons should be top bottom, it would also make it easier to use the buttons. (@suunto)
-temperature function basically reads 10 degeees less than my body temperature (should I be wearing it on the outside of my jacket?)
Compass is extremely sensitive to hand position. (Keeping hand steady and level)

Sunnto all day!!

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

lets just say that I purchased this for my brother in law but he ended up with a different one. this one stays with me this watch is for all outdoor activity's.
I can go from rock climbing to cliff jumping to hiking to scuba and not worry.
the features are amazing from compass to elevation this thing will track it all. This is a great purchase you will not be let down.

Best Outdoor / Street Casual Watch

    Great Watch , looks and function very stream solid look .
    can be used for outdoor and still great city dressed watch
    Got black blue prints with grey band !

    Small-wristed women, have no fear!

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

    I just got this as a gift from my bf and was a little concerned when I first saw it that the clock face would be way to big for my small wrist. However, the strap connects to the watch face with a cool kind of 'dual pivot' design, making it fit really comfortably (on the smallest setting on the band). It'll take a little getting used to, coming from a much smaller watch, but it looks really nice and seems very well built and designed. Can't wait to get it up in the mountains!

    Small-wristed women, have no fear!

    It is a lot of watch!

    • Familiarity: I've used it several times
    • Fit: Runs small

    It is well built, accurate, and reliable. Clean interface and many features without becoming cluttered. Short learning curve to use. I like the lugs where the watch joins the band, makes for an better fit on smaller wrists. Only con is on the 'military' or black face watch, it is not easy to read in minimal light. Very easy to read in full blinding sunlight or at night with the backlight, but not in twilight... Overall I do like the watch but took off one star due to the display being hard to read in low light. I would still buy and recommend this watch though as it is very useful!

    Outdoor Gear Lab Top Pick

    Outdoor Gear Lab tested five of the best altimeter watches on the market in side-by-side tests over a year. These watches feature the key functions that hikers, backpackers, and climbers use the most: altimeter, barometer, digital compass, and standard time-keeping features.

    Still have some reading to do...

    I'm a bit slow... need to take the time to read over the manual and figure it all out (specially since none of the buttons are labeled).

    It is true to size and I have super tiny wrists, so I'm happy that it just fit (on the second to last setting on the wrist band). Think it will be a great watch!

    Still have some reading to do...

    So I used this watch for a 30 day backcountry traverse... Was super happy with the alarm, altitude and barometer readings... lots of other features!

    Does anyone know if the Core has any kind...

    Does anyone know if the Core has any kind of digital "sweeping" seconds hand. It helps me with counting vitals. I am looking for some sort of altimeter watch that also has more of an analogue style seconds hand. Any info/feedback would be very helpful


    Best Answer

    I have the Core and YES, it does have a sweeping seconds "hand" in one of the views.... I bought it for the same purpose after getting my WFA cert.

    There's also an uber-useful countdown timer that's great for setting intervals for when you need to go back and record vitals...

    Thanks so much Dave!!! Now I know what is on the top of my x-mass list :)

    You're very welcome. I've been enjoying the Core quite a bit, though I'm not exactly exploring the Arctic with it. Biggest surprise is how often people say "wow... nice watch! what is that?"

    Great Watch - Active

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

    I love this watch. Great wristband, I have the RED color. Function navigation is easy and it becomes second nature to ABC!

    Been with suunto a long time...

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

    I started wearing suunto watches back in 1999 when I purchased my first one In Graffenwoehr, Germany right before going on a field exercise for the military. I bought a Suunto Vector and I took it everywhere. I took it to Afghanistan on 2 tours and I took it to Iraq for 2 years. It survived all of the heat, sand, dust and rattling of the track vehicles we cruised around in. I had that watch until 2010 when I finally retired it and upgraded to the Core. The core is a sleeker model with updated functions much of them the same. This model has added a much larger log system and a more accurate barometer and altimeter. I use it in the rockies on 14rs and am always within 5-10 meters of my actual location. The band can wear out over a couple of years. I replaced my 1x since I bought it but other than that, the casing and the watch itself have been flawless. This has been the best watch I have ever owned, and would recommend it if you use altimeters and or barometers often for outdoor adventures.

    Thanks for the review, I have been a Suunto owner for a long time and want to add this to my collection. Thanks for your insights!

    Nice time-piece...wish I still had it

    • Familiarity: I've put it through the wringer

    So I bought the Core as a grad present for myself after getting my MS. I fell in love instantly. The watch is pretty large, for those of us that like the oversized face look. The functions are easy to learn, it only took me 10 mins. The barometer/altimeter is pretty fickle, but most watches of this design are. IT is importante to reset the alti as often as you can with known altitudes (summits, valleys, and base camps) as needed to keep you honest. The storm alarm has saved me more than once when I was ignorant to ignore the weather.

    My only complaint is a common one for this piece, it fogs up pretty badly once you dunk it. It really is waterproof!! All of the functions worked fine after a 10M underwater snorkel in the Cayman's , but after that, the fog never went away. I returned it for this reason only. But kinda wish I didn't...really wish I didn't...That's it! I'm buying another one...

    Buy em up! Great watch! Easy to use! Sick looks! Screams Explorer!

    Nice time-piece...wish I still had it

    Suunto Core (orange)

      Bought about 2y ago and still on 1 battery, great features as nearly all Suunto's... but 1 thing I'm really annoyed by and that is the orange plastic wrist band - over time and it might took 3m max it got DIRTY! not dirty from wearing/showering etc it discolors to a black tone/color but overall looks like I'm the biggest dirtbag!

      Also after about 2 year the plastic's elasticity was lost and it broke.

      replacing it is quite expensive - paying $300 for the watch and supposed to pay between $60-80 for a plastic wrist band ?!

      Still waiting that the price drops, the watch breaks and I rather get a new one then paying for overpriced wrist band...

      Go Core

        All the basic & beyond features in an altitude (height or depth) watch with altimeter, barometer, weather trend indicator, storm alarm, digital compass & thermostat and much more (including all the normal watch features as well). Fun colors, good fit, and extremely reliable. Does the trick for most, if not all, outdoor applications. Does not include heart rate monitor.
