Garmin Forerunner 170 Review: AMOLED Running Watch at $299

What It Is

The Garmin Forerunner 170 is a mid-range running watch positioned at $299.99 / £259.99, sitting just above the new Forerunner 70 ($249.99 / £219.99) in Garmin's refreshed entry-to-mid lineup. It targets recreational runners and fitness-focused users who want Garmin's full physiological tracking suite without stepping up to the Forerunner 265 or 965 price bracket. Crucially, this generation marks the end of MIP displays across the Forerunner line, with AMOLED now standard even at this price point.

Key Specs

The sources available at the time of writing are limited to announcement-level information and early leak analysis, so a full technical breakdown is not yet possible with verified numbers. What is confirmed:

• Display: AMOLED (MIP has been fully retired from the Forerunner lineup with this generation)
• Physiological sensors: Full physio stack, described as equivalent to higher-tier Forerunner models, which typically includes wrist-based optical PPG heart rate, HRV tracking, SpO2 blood oxygen saturation, skin temperature, and a barometric altimeter
• Price: $299.99 / £259.99
• GPS: Expected multi-band or standard GNSS satellite positioning, consistent with Garmin's current mid-range offerings, though chipset specifics are unconfirmed
• Battery life, weight, and water resistance: Not confirmed in available sources at time of writing

Performance in the Real World

Here is the honest problem with reviewing the Forerunner 170 right now: the sources available are a brief announcement summary and a leak credibility analysis. Neither provides real-world GPS accuracy figures, heart rate deviation data during intervals, sleep tracking quality assessments, or any hands-on time with the device. Writing specific numbers here would be fabrication, and you deserve better than that.

What can be said with confidence is that the shift to AMOLED at this price tier is meaningful. MIP screens are readable in direct sunlight but look dated next to the vivid displays on competing watches like the Apple Watch SE or the COROS Pace 3. Garmin's AMOLED implementation on the Forerunner 265 has been well-regarded for outdoor visibility when the always-on mode is configured correctly, and the 170 should inherit that approach.

The inclusion of Garmin's full physiological stack at this price is the headline. On devices like the Forerunner 265, HRV Status uses overnight PPG optical data to calculate beat-to-beat variation and feeds into the Body Battery metric. Skin temperature sensors on Garmin devices feed into menstrual cycle tracking and illness detection features. SpO2 monitoring uses optical sensors, not electrical signals, and on Garmin devices is typically available as an on-demand reading or overnight spot-check rather than continuous tracking, which helps preserve battery life. Whether the 170 handles these features identically to the 265 or with any limitations is not yet confirmed.

The barometric altimeter, if included as expected, measures air pressure changes to calculate elevation gain rather than relying on GPS altitude, which is notoriously imprecise. This matters for trail runners counting vertical meters.

App ecosystem is standard Garmin Connect, which remains one of the most comprehensive platforms for running analytics, training load, and long-term trend tracking. Garmin Connect IQ third-party app support is expected at this tier.

Who It's For / Who Should Skip It

The Forerunner 170 makes sense for runners who previously looked at the Forerunner 55 or 165 and wanted more physiological depth without jumping to $449 for a Forerunner 265. If you want Garmin's HRV Status, Body Battery, skin temperature tracking, and an AMOLED display under $300, this is now the entry point for that combination.

Skip it if you are a serious multisport athlete. At $299.99, you are still missing the mapping capabilities and full triathlon modes that define the Forerunner 265 and above. Skip it also if you are coming from a Forerunner 165, where the upgrade case is not yet clear enough to justify the price difference without more detailed comparative data.

Runners considering the COROS Pace 3 at around $229 will find a compelling alternative with strong GPS performance and exceptional battery life, though COROS's physiological tracking depth does not match Garmin's ecosystem. The Forerunner 170 is betting that the full Garmin stack plus AMOLED justifies the premium over COROS at this tier.

Verdict

The Forerunner 170 looks like a smart repositioning of Garmin's mid-range lineup, bringing AMOLED and the full physiological sensor suite to a price point that was previously occupied by more limited hardware. Real-world performance data is not yet available to confirm whether it delivers on that promise. Check back once hands-on reviews are published before buying.
