Absolutely love this watch. Used it for a few tours in the Wasatch already and its has been a great tool.

Unanswered Question

I'm very interested in purchasing the core, my struggle is picking between the all black and the ultimate black. Besides looks is there any differences between the two?

The Core has been a great watch for me. I have had it for close to 6 months. (Purchased from

Please see photo. I suddenly got lines on my screen. Is this a battery issue or is screen going out on me?

Thank you in advance


Hey Dayne, best bet is to check directly with Suunto, perhaps they can help you troubleshoot.


Holds Up Well!!

It's still going strong, I wear this anytime I'm doing an outdoor activity. Took it snorkeling, mtbing, hiking, kayaking, swimming, and just about everywhere else. So far so good! Only issues is it seems the altimeter gets off and needs to be reprogrammed every so often.Battery has also lasted longer than I expected but when the time comes it will be super easy to switch out.

This is my first experience with Suunto. The watch is full of features, few of which I actually use. There is a convenient "lock" function which prevents you from inadvertently switching modes. The paint began to flake from the face almost immediately. More recently, the strap retainer and strap itself have broken and need to be replaced.

Suunto and salmon fly time!

Pretty cool

  • Familiarity:I've used it several times

I bought this watch as an altimeter to skydive with. It does a decent job falling at 120MPH. Very durable watch, can take whatever you throw at it.

I love this watch and everything it has to offer! It's great for backpacking adventures and even everyday use.

Absolutely love this thing!

Perfect Watch

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

I bought the Suunto Core in Sahara Yellow. The watch is fairly large but it feels like it weighs close to nothing! It's so comfortable I actually forget that I'm wearing it. The instruments are really accurate and reliable. Perfect watch. My only issues are that it can be a little tough to see the numbers in bright sunlight and the alarms aren't really loud enough IMHO.


too complicated

  • Familiarity:I returned this product before using it

lack of instructions makes this watch impossible to figure out


Everything you need, plus more

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

I have worn this watch almost everyday for the past 18 months. I have used it, in addition to my daily routine, mountain biking, running, and backpacking.

I took it out for a three month stint working as a part of a trail crew building and repairing trail. I was worried that working with rocks and tools I would damage the face of the watch. After the end, the glass face is in excellent condition with just one small scratch. The outer edges did get scratched quite a bit, but it is only cosmetic. (In my opinion I think it looks good- showing this watch has been places)

Over the course of my daily routine, I only use it to look at the time. The screen is beautiful and shows everything you need. I have received many compliments. Though there is a learning curve, it is not that bad to figure out how to use all of the features well. Sometimes I want to see the altitude I'm at when travelling, so the "auto" mode works well for that. (Adjusts between barometer and altimeter automatically- impossible to view both at same time because altitude is calculated from pressure) Keep in mind the temperature will be about 15 degrees higher than the ambient temperature. To find the ambient temperature, just take off the watch and strap it to your backpack. You'll have an accurate reading in 15 minutes.

I have yet to change the battery. I think the time is coming soon though.

The biggest qualm I have is that the strap ended up breaking after being bent so many times when I put it on and off. Unfortunately, my warranty just ran out so I had to buy a new one. $35 from Suunto was a bit steep, even when on sale. Another minor thing is getting used to the watch. It's on the bigger side- not huge- but just a bit larger than the average watch. The strap feels a bit strange at first. Now though, I barely notice it.


Cool watch. A couple drawbacks

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 5'10"
    Weight: 155 lbs
    Size Purchased: One Size

The watch it surprisingly light. I like the strap and the way it fits. The large numbers are cool as well. The temperature gauge is off by around 10 degrees since the sensor is so close to the skin. Also, I'd like to be able to see the barometer and the altimeter at the same time. Other than that, I love it.


Suunto.... why such a weak strap

  • Familiarity:I've put it through the wringer
  • Height: 6'2"
    Weight: 240 lbs

Great watch. Has all the bells and whistles. Its a little bulky but that did not bother me one bit. However the straps....

1. It was always too tight or too loose. I could never get the right sizing because of the strap.

2. Why the weak strap Suunto??? Strap lasted just under a year. I am on my 3rd strap. Very weak breaks easily.

Watch still looks BAD AXX and its tough


Awesome Watch

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

This is super badass watch, I love it. Very light, comfortable strap. It has a lot of functionality. Instructions aren't great but very straightforward.


bday present for boyfriend

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

i haven't used this myself, but i know my boyfriend loves it. he takes it on all of his big backcountry tours to track total elevation climbed and on major backpacking and climbing trips. haven't heard any complaints from him about it.

Hi, is that possible to switch from ft to meters? On the screen.


Best Answer

Yes. it will do metric or standard (feet/meters, *f/*C, etc.). It's an option in the menu setting. You can also do 12/24 hrs clock.

Press and hold Mode button (middle right).

Scroll down using -/light button to "Units"
