What reviewers say

Distilled from the video reviewers — the score, what they praise, where they push back.?

Pace 3
across 5 reviews
4.5/5
mixed
Reviewers praise
  • Multi-band dual-frequency GPS outperforms price bracket and matches far more expensive watches
  • Battery life exceeds manufacturer claims in real-world testing, lasting weeks between charges even with GPS-intensive activities
  • Lightweight build at 30 grams makes it barely noticeable during runs and all-day wear
Reviewers push back
  • Memory-in-pixel display is dimmer indoors than AMOLED competitors, though excellent in sunlight
  • Music playback limited to MP3 files loaded via computer—no streaming service support
  • Touchscreen disabled by default in many menus, requiring manual setting changes for full functionality
Reviewers agree the Pace 3 delivers exceptional GPS accuracy, battery life, and software experience at an entry-level price, making it the standout budget running watch despite minor interface quirks.
— best for: Runners and multi-sport athletes who prioritize accurate tracking, long battery life, and clean training data over smartwatch features or streaming music.
Pacer Pro

3.5/5

Reviewers praise
  • Barometric altimeter enables wrist-based running power and hill-splitter features without accessories
  • Route navigation and Strava Live Segments now included at this price point
  • Extremely lightweight at 40–41 grams with comfortable silicone band and improved screen clarity
Reviewers push back
  • Heart rate tracking struggles outdoors with delayed response to intensity changes and frequent underreporting
  • GPS accuracy lags behind competitors in certain conditions
  • No touchscreen despite upgraded display
I think polaris probably cut off the majority of people's reasons to buy those higher end watches today
DC Rainmaker · best for Runners seeking advanced training metrics like running power and hill repeats who prioritize light weight and long battery over perfect sensor accuracy.

Where reviewers split on Pace 3: One reviewer emphasizes Garmin frustrations driving the switch, while others compare objectively without brand grievances On Pacer Pro: One reviewer found heart rate accuracy problematic for outdoor cycling with significant misdetections, while others reported generally acceptable performance for running

This watch is fantastic. As an avid adventurer with many different outdoor pursuits, it has everything I need and nothing I don’t. I’ve used it to track hikes, walks, runs, bike rides, open water swims and inline skating. It has a multi sport option for when I am doing multiple activities but not in triathlon order/events. Haven’t used it yet for a backpacking trip but I’m confident it will be up Lorem · mec.ca

I've been using this watch as my daily watch now for 3 weeks, it's excellent. Previously I was using a Google Pixel Watch, and using that for running, the difference is like chalk and cheese. This watch also features what we now expect as standard on a smartwatch: Step count, HRM, Sleep tracker & also features more advanced options such as training load and readiness.
