Suunto is awesome. I love their stuff. I've had several of their watches and I have taken them from South Africa to Alaska.
Here is the problem with Suunto watches today. There are so many smart watches available that you can install an 'app' to do everything the Suunto does eg Apple Watch etc...
So where is the Suunto watch useful today? Well if you are a heavy duty backpacker, pushing 7-10 days of hiking, get a Suunto. If you are a weekend warrior pushing out 8 hour hikes on Saturday, then stick with your smart phone accessory.
Specifically the Core is awesome because it is the barebone, essential Suunto watch. It gives you want you the stats you want in accomplishing your latest alpine adventure. That being said, I know of several purists who avoid the digital watch solution, and instead stick with more fine tuned instruments to accompany their adventure. A simple chronographic watch can help you find North just as easily as a Suunto watch. Altitude, temp, pressure etc can be better tuned with individual instruments. But if you're looking for general neighborhood stats, this is good for that.
Overall though I like this watch, I like the aesthetic, and I always smile when I see a stranger repping good gear.
