Nothing tests the reliability of a smartwatch quite like a real-world walk—but here's where it gets interesting... When comparing the newest models, the Apple Watch Series 11 and the Apple Watch SE 3, you might think the choice is clear-cut. However, my experience walking 5,550 steps with both devices revealed some surprising discrepancies that might challenge your assumptions.
As you probably know, both the Apple Watch 11 and the SE 3 are considered top contenders in the smartwatch market—two of the best options available today, and exemplary for all-around smartwatch capabilities. They excel across many features, making them popular choices among fitness enthusiasts and tech lovers alike.
Previously, I delved into an in-depth comparison of these two models, but here’s a quick summary for those pressed for time: The flagship Apple Watch Series 11, starting at $399, offers more advanced health and fitness monitoring, a display that’s brighter, and improved battery life—features that appeal to those wanting the cutting edge.
On the other hand, the Apple Watch SE 3, priced more affordably at $249, shares many core features with the Series 11, including seamless app integration and compatibility within the Apple ecosystem But, it skips out on certain health features like hypertension alerts, ECG capabilities, and blood oxygen (SpO2) monitoring, which might be a deal-breaker for some serious health tracking.
Both watches provide similar fitness tracking functionality, with multiple workout modes and post-exercise insights accessible through Apple’s Workout app. While the Series 11 boasts a more sophisticated heart rate sensor, they both use comparable single-band GPS antennas, ensuring reliable location tracking.
The Step-by-Step Walk Test: Comparing Performance in Real Life
To truly evaluate how these devices perform during an outdoor activity, I strapped the SE 3 to my left wrist and the Series 11 to my right. I initiated a guided outdoor walking session on both, aiming to see how accurately each device recorded my steps, distance, elevation, and pace.
As a control measure, I manually counted every hundred steps using a tally counter, resetting the count each time to ensure precision. For additional data points like total distance, elevation gain, and pace, I also tracked the walk via Strava on my phone, keeping Bluetooth off to prevent data crossover.
Here are the results:
| Feature | Apple Watch 11 | Apple Watch SE 3 | Manual Count | Strava Tracking |
|---|---|---|---|---|
| Step count | 5,467 | 5,500 | 5,500 | 5,502 |
| Distance (miles) | 2.97 | 2.95 | N/A | 3.15 |
| Elevation gain (feet) | 513 | 540 | N/A | 426 |
| Average pace | 17:32/mile | 18:06/mile | N/A | 16:32/mile |
| Avg heart rate | 135 bpm | 137 bpm | N/A | N/A |
| Max heart rate | 168 bpm | 168 bpm | N/A | N/A |
| Calories burned | 425 | 429 | N/A | N/A |
| Battery consumption | 2% | 2% | N/A | N/A |
Despite the weather turning rainy and chilly, I was genuinely surprised that the SE 3 hit the 5,500-step mark exactly, matching my manual count perfectly. Meanwhile, the Series 11 was just 33 steps shy, registering 5,467—a difference so minor it’s almost imperceptible.
In terms of distance, Strava’s outdoor tracking suggested I had actually covered a slightly longer route—around 3.15 miles—more than both watches indicated. The elevation data was similarly inconsistent; the Series 11 overestimated elevation gain, while the SE 3 slightly overcounted with higher feet climbed than Strava recorded, despite the walk involving noticeable hills.
Pace calculations told a different story. Strava’s time suggested I was moving faster than both the Apple Watches indicated, with my overall pace appearing about a minute per mile quicker. Despite these small differences, heart rate and calories burned measurements were remarkably consistent between the devices.
So, who wins this walk challenge?
The SE 3's perfect step count makes it a champion for tracking daily activity—especially if your priority is counting steps accurately. However, the Series 11 provided more precise data on distance and elevation, which could matter if you're aiming to measure more detailed fitness metrics.
Both devices performed similarly in heart rate monitoring and battery efficiency—they each drained just 2% during this 52-minute outdoor session, which is impressive in terms of power management.
Final verdict: In this simple test, the Apple Watch SE 3 outperformed the Series 11 in step accuracy, but the Series 11 beats slightly in distance and altitude measurement. This raises a fundamental question: Are we truly prioritizing step counts over other metrics in everyday fitness, or should we look for a device that balances all aspects?
I'd love to hear your thoughts—do you agree that accurate step counting matters most, or do the detailed metrics like elevation and pace hold more value for your fitness goals?
