The Garmin Fenix 7 is one of our picks for the best GPS running watches you can buy — and for good reason. Not only is the battery life phenomenal, it comes with accurate GPS tracking, heart-rate monitoring, tones of multi-sports modes, in-depth running analytics, sleep score, morning report and more. And right now, in the Amazon Prime Day sale, you can save on just about every size model: from 30% off the standard 7 to 33% off the 7X Solar.

Also: The best Prime Day health and fitness deals

I wear the Garmin Fenix 7 Pro pretty much 24/7 and it's essentially what you get when you cross a high-spec training tool with a sleek smartwatch. It packs an impressive battery life of 22 days in smartwatch mode (or 73 hours with GPS), military-style multi-band GPS (designed to improve GPS accuracy), new training features and a much-more accurate heart rate monitor. It's one of the best Garmin watches you can buy — and one of the top Prime Day Garmin deals I've spotted so far.

What everyone's reading

But the Fenix 7 comes in various other iterations, with each model offering a different Amazon Prime Day discount: 7S is the smallest at 42mm; the 7 measures 47mm; and the 7X comes in at a hefty 51mm.

As well as size options, there is a choice of materials, meaning you can opt for a Standard, Solar, or Sapphire Solar model. And then there's the Fenix 7 Pro which offers more advanced features.
