Garmin Forerunner 170 GPS Running Smartwatch

The Garmin Forerunner 170 GPS Running Smartwatch is a GPS running watch purpose-built to let everyone know you're a runner. Pool swims log as easily as runs, thanks to a 5 ATM water rating. Morning and evening reports bookend each day with your sleep and training. Acute load shows each week's training adding up. On early runs, runners can switch on the always-on display and keep the watch face lit between glances. Colors are Black with Amp Yellow or Whitestone with Cloud Blue, with a charging cable and documentation in the box.

The Forerunner 170 is the watch you reach for when you've outrun your first fitness tracker. Next to Garmin's entry-level Forerunner 70, it adds the full sensor stack a serious runner actually uses: barometric altimeter, three-axis compass, gyroscope, thermometer, and tap-to-pay.

You still get the same 1.2-inch AMOLED touchscreen, the same triple-system GPS (GPS + GLONASS + Galileo), the same Garmin Coach adaptive training plans, the same Training Readiness score that tells you each morning whether to push or recover. What changes is what the watch can measure while you're running: elevation gain on real climbs instead of estimated from GPS, and true compass heading when you're navigating. It also has a thermometer. Buy your post-workout coffee from your wrist with Garmin Pay.

Morning to evening

How it works

Morning and evening reports
Your day opens with the morning report, a summary of your sleep, recovery and planned training when you wake. Beside it sits training readiness, a daily score built from your sleep, recovery and recent training load. An evening report before bed closes the day.
Acute load
Acute load adds up the strain of your recent workouts. Seeing it climb shows how quickly a new training block is building.
Running power
Wrist-based running power measures your output on every run, shown beside pace and heart rate.
Always-on display
On the 170, the screen is AMOLED, a display where each pixel makes its own light. Switch on the optional always-on mode and the watch face stays lit between glances.

Frequently asked questions

The 170 adds a barometric altimeter, three-axis compass, gyroscope, thermometer, and Garmin Pay contactless payments. It also has 4 GB of memory, up from 512 MB. In exchange, battery life drops from 13 days to 10 in smartwatch mode, and from 23 hours to 20 in GPS mode. Both watches share the same display, the same triple-system GPS, the same Garmin Coach training plans, and the same recovery science (Training Readiness, Body Battery, sleep stages).
The barometric altimeter reads within about 10 feet of true elevation gain, compared to 50-100 feet of drift on GPS-only watches. Calibration happens automatically when you start an activity outdoors. On long runs with sustained climbs, you'll see your watch and a calibrated trail map agree within a few feet, something a GPS-only watch can't promise.
It controls the music on your smartphone from the wrist. The 4 GB of memory holds activity data, settings, and watch faces, and the Forerunner 170 Music adds storage for offline playlists.
Garmin Pay supports most major US and Canadian banks running on Visa, Mastercard, and American Express networks. Once added in the Garmin Connect app, tap-to-pay works at supported terminals.
Yes. The Forerunner 170 receives signals from three systems (GPS, GLONASS and Galileo) and uses the strongest available, which is more accurate than single-system GPS watches in tree cover, urban areas, and canyons.
Up to 10 days in smartwatch mode with notifications and 24/7 heart rate active, up to 20 hours with continuous GPS, and up to 19 days in Battery Saver smartwatch mode. Real-world numbers depend on how often you train, screen-on time, and whether you use the always-on display setting. With four to six hours of GPS workouts a week, expect to charge every 7-10 days.
The included silicone band fits wrist circumferences from 126 to 203 mm (roughly 5.0 to 8.0 inches). The 42.6 mm case sits low-profile thanks to the 1.2-inch display and 41-gram weight, and the band uses 20 mm industry-standard quick-release pins. It pairs with both iPhone and Android via the free Garmin Connect app. Text replies from the wrist need an Android phone or the Garmin Messenger app.
