'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services.

The Fenix 7 Pro line consists of two models: the Pro Solar and Pro Sapphire Solar, each offered in three sizes: 42mm Fenix 7S, 47mm Fenix 7, and 51mm Fenix 7X.
The sizes are pretty easy to understand -- think small, medium, and large -- and they're available in two crystal options: glass and sapphire.
The Fenix 7S and 7 are also offered in silver alongside the matte black DLC (diamond-like coating), and there are a smattering of different band colors, too.
While six different offerings might seem awfully complicated, it's a lot simpler than before. Now all the models come with solar charging, all come with a built-in white/red LED flashlight, and all have 32GB of storage.
In the run-up to this review, I'd been wearing the Fenix 7X for a few weeks. And when I switched to the Fenix 7X Pro, there were a few things I noticed straight away.
First, the heart rate/pulse ox sensor is an updated module. It's a bigger unit, spacing out the LEDs that take the readings; the update's goal is to offer more accurate readings under conditions where the wrist is being bent and flexed. I never had much of a problem with the previous heart rate/pulse ox monitor, but I do find that this suffers fewer dropouts, both at night and when hiking with walking poles.
Another thing I noticed right away is that the display on the Fenix 7X Pro has more pop than that of the Fenix 7. The display is crisper and clearer, and the colors are brighter.
It's hard to quantify, but the display just feels better on the eyes.
The white/red LED flashlight has also been updated and is both brighter and offers a more focused beam of light to pierce the darkness (and is now offered on all the models).
I've only been testing the Fenix 7 Pro for about a week, but I can already tell that this is a winner. It builds intelligently on the Fenix 7 platform, streamlining the lineup in such a way that buyers only need to think about the size of the watch (or, put another way, price).
Fenix 7X owners can probably ignore this upgrade as they have most of what this model offers. And those who went for the Fenix 7S or Fenix 7 and feel they are missing out on solar charging or a flashlight, well, now those features are available. But those who'll benefit most from this update are the users of earlier Garmin models -- or those coming from another smartwatch brand-- even the Apple Watch.
As a long-time Apple Watch owner, the Fenix 7X Pro's big display -- dwarfing even that of the Apple Watch Ultra -- and the weeks of battery life are the things that I appreciate most about this smartwatch. The use of buttons rather than the heavy reliance on a touchscreen is also super handy, making this much easier to operate in wet weather. And the built-in maps mean that I can go totally off-grid and still know where I am, wherever I happen to end up.
