To determine which device excels as a fitness tracker, I conducted a practical test by wearing the Apple Watch Series 12 on one wrist and the Garmin Forerunner 170 on the other during a 5,000-step walk. Both models are popular choices, though they cater to slightly different needs: the Apple Watch serves as a premium, feature-rich smartwatch, while the Forerunner acts as a budget-conscious option tailored for runners.


Design and Price Considerations

There is a notable price difference between the two devices. The Garmin Forerunner 170 starts at $349, whereas the Apple Watch Series 12 ranges from $399 to $549. In terms of design, the Garmin utilizes a plastic casing available in various sporty colors, making it quite lightweight. Conversely, the Apple Watch features a more premium aluminum build, though this results in a heavier feel on the wrist.


Methodology

To ensure accuracy, I manually counted my steps (totaling 5,014) and utilized the Strava app as a benchmark for measuring distance, pace, and elevation. By configuring the watches to recognize which wrist they were worn on, I aimed to eliminate potential tracking biases.


Tracking Results

The results of the head-to-head comparison were remarkably close:

  • Step Count: Both devices performed excellently. The Apple Watch Series 12 undercounted by only 11 steps, while the Garmin Forerunner 170 overcounted by just six.
  • Elevation Accuracy: The Garmin proved superior here, showing an error of only six feet compared to the control, whereas the Apple Watch overstated the climb by 28 feet.
  • Pace Tracking: While the Apple Watch was more aligned with the control's elapsed pace metrics, both devices provided reliable data.
  • Heart Rate: Both wearables delivered identical average and maximum heart rate readings throughout the 50-minute exercise.

Battery and Final Verdict

While Garmin is often associated with superior battery longevity, this test highlighted that the Apple Watch Series 12 holds its own when GPS and heart rate monitoring are engaged continuously.


Ultimately, the choice depends on your priorities. The Forerunner 170 offered slightly better accuracy for step counting and elevation, making it a strong contender for dedicated athletes, while the Apple Watch Series 12 remains the more versatile everyday smartwatch with a wider ecosystem of applications.
