Polar Grit X vs. Polar Grit X Pro and Polar Grit X Pro Titan: Which Is The Best Outdoor Watch For Me?

It’s time to check out the difference between Polar Outdoor Watches: Polar Grit X vs. Polar Grit X Pro (and Titan).

If you’re into trail running, mountain biking, hiking, climbing and bouldering, or any other outdoor sports, you know that having the right gear can make all the difference.

There’s a lot of good options out there – but with Polar Grit X and the introduction of the NEW Polar Grit X Pro and Polar Grit X Pro Titan, you now have some great ones!

Our solid trio of rough and rugged outdoor watches will help you explore, discover, and navigate the world, and train in nature.

If you’re about to head out on an epic adventure and don’t want to spend another second reading a blog post, know this:

Polar Grit X is a VERY GOOD CHOICE!

Polar Grit X Pro is BETTER!

Polar Grit X Pro Titan is THE BEST!

Now, if you have a minute or two to spare, let’s take a closer look at the toughest Polar watches to date:


Meet Polar's Outdoor Watch Family.

The Polar Grit X family is now complete!

We released the Polar Grit X into the wild back in early 2020: since then, it’s been breaking new ground and blazing trails, carving a path to make way for the arrival of Polar Grit X Pro and the immovable Polar Grit X Pro Titan.

All three outdoor watches are built to military-level standards; they’re all equipped with ultra-long battery life; each has essential training and navigation tools built in; and of course, they wouldn’t be Polar watches if they didn’t have incredibly accurate GPS and our world-renowned Polar Precision Prime™ wrist-based optical heart rate tracking technology.

So, what’s the difference?

Which is the best Outdoor Watch for you?

And what justifies the prices? *Yeah, we guessed that question would come up!

It’s time to explore!


The most glaringly obvious way to tell these three apart is in the way they look and feel.

Polar Grit X really is a beautiful watch; crafted to handle some pretty big demands and made to be extremely durable with a stainless-steel bezel and Gorilla glass lens – there’s not much it can’t deal with.

In Polar Grit X Pro and Polar Grit X Pro Titan, we swapped out the Gorilla glass lens for one of the strongest transparent minerals on earth, sapphire. It’s scratch-resistant, more durable, and offers a more superior quality than its predecessor.

We also added deco detailing around the bezel with compass etchings.

Right now, we’re only looking at design – and the Grit X Pro Titan needs a section unto itself


Polar Grit X Pro Titan: Lighter, Stronger, More Adaptable.

This is where things get a bit more exciting.

Stainless-steel is tough, but if you have more extreme demands, you’re going to need something stronger.

Polar Grit X Pro Titan is the lightest, toughest, and most adaptable watch in our Outdoor category.

Aerospace titanium provides the highest strength-to-density ratio of any metallic element – it’s also lighter and more durable than stainless-steel. We chose it for the bezel of the Grit X Pro Titan so you can handle any demand.

When you choose Polar Grit X Pro Titan, you’re also getting more options straight out of the box: with not one, but TWO Wristbands included.

Premium FKM (fluoroelastomer) bands are completely weatherproof and look & feel great on your wrist. They’re perfect for sports and are made for ANY condition.

Perforated Leather bands offer stylish detailing and provide that extra touch of class so that you can wear your military-grade watch anytime you want – perfect for more formal situations and made for ANY occasion.

With the Perforated Leather band attached to your Grit X Pro Titan, you’ll have the lightest outdoor watch in our line-up with a total weight of just 53g.

If you want to upgrade your equipment for more extreme demands, choose Polar Grit X Pro Titan.

*In terms of features, software, hardware, and capabilities, Polar Grit X Pro Titan is identical to the Polar Grit X Pro: for that reason, from this point on, when we refer to Polar Grit X Pro in this article, you can take that to also include Polar Grit X Pro Titan.


Not really, but we understand why you might think that.

Before we go on, let’s round up all the specs shared by the watches in the Grit X family:

Yes, there will be!

If you’re considering buying the Polar Grit X, or if you already have one and you’re worried that you are missing out on some of the new features that come with Polar Grit X Pro, fear not.

Of course, we can’t bring everything over from Grit X Pro, but Polar Grit X will be getting the following features via a 2.0 software update at the end of 2021:

  • Music Controls
  • HR Sensor Mode
  • Running Performance Test
  • Weekly Summary Dashboard

  • Silence a phone call from the watch. 
  • Fully customizable quick settings menu (flight mode, do not disturb, alarm, countdown timer). 


Whilst Polar Grit X Pro and Polar Grit X Pro Titan are both incredible new watches, there’s no denying that Polar Grit X can still hold its own.

It may not have as many features and it may not be as capable of handling more extreme demands, but it certainly does the job.

If you’re the kind of person who wants to train outdoors, explore the world, and get lost in the thrill of adventure, Polar Grit X is an excellent choice and will provide you with everything you need.

If, however, you want to push the limits of what you can do out there – heading deeper into the unknown and really going up against nature – you’ll need to gear up for battle.

You’re going to face some of the toughest, most physically demanding challenges under the most extreme conditions and you need to know your equipment won’t let you down.

If that sounds like something you’d be interested in, choose Polar Grit X Pro.

If it sounds like ‘another day in the life’ to you, choose Polar Grit X Pro Titan.
