Garmin Forerunner 165 Overview
The Garmin Forerunner 165 is a running-focused GPS smartwatch built for runners who want dedicated training, health and activity features in a relatively lightweight design.
Its biggest visual change compared with Garmin's older Forerunner models is the 1.2-inch AMOLED display, which provides a colorful 390 × 390-pixel interface and supports touch interaction.
The watch weighs approximately 39 grams and is rated to 5 ATM for water resistance.
GPS tracking, running metrics, training features, recovery information and health monitoring form the core of the Forerunner 165 experience.
Display: 1.2-inch AMOLED
The Forerunner 165 features a 1.2-inch AMOLED display with a resolution of 390 × 390 pixels.
The screen supports touch interaction and an optional always-on display mode.
Garmin combines the touchscreen with physical buttons, allowing users to navigate the watch during workouts without relying only on touch controls.
The AMOLED panel provides a colorful interface for viewing workout data, notifications, health information and watch faces.
GPS & Outdoor Tracking
Built-in satellite positioning is one of the most important features of the Forerunner 165.
Garmin rates the watch for up to 19 hours in GPS-only GNSS mode and up to 17 hours in All-Systems GNSS mode.
The watch can therefore record outdoor running, walking and other compatible activities without requiring the phone to provide the GPS signal.
For runners, built-in GNSS allows distance, pace and route-related activity information to be recorded directly from the watch.
Running Training Features
The Forerunner 165 is designed specifically around running and provides a range of training-oriented metrics and features.
Garmin's platform provides workout guidance, running dynamics, recovery-related information and other training data designed to help runners understand their activity.
The watch can also provide daily suggested workouts and training-related information depending on the user's activity history and compatible features.
The Forerunner 165 is intended to help runners structure training rather than simply record steps and workouts.
Health & Wellness Tracking
The watch includes wrist-based heart-rate monitoring and Pulse Ox blood oxygen measurement.
Garmin also provides sleep score and sleep insights, along with other wellness and activity information.
The Forerunner 165 can monitor heart rate continuously and provide health information throughout the day, subject to Garmin's supported features and settings.
Health measurements from consumer wearables are intended for general wellness purposes and are not a substitute for medical diagnosis.
Battery: Up to 11 Days
Garmin rates the Forerunner 165 for up to 11 days in smartwatch mode.
In Battery Saver Smartwatch mode, Garmin lists up to 20 days.
GPS usage naturally reduces battery life. Garmin lists up to 19 hours in GPS-only mode and up to 17 hours in All-Systems GNSS mode.
With music playback on the Music version, Garmin lists up to 7 hours in GPS-only mode and 6.5 hours in All-Systems mode.
Always-on display, GPS, heart-rate tracking, notifications, connected sensors and other features can reduce actual battery life compared with the maximum ratings.
Smartwatch Features
The Forerunner 165 is more than a running tracker. It can show smartphone notifications and provides everyday smartwatch functions alongside its fitness features.
The watch also supports Garmin Pay for compatible payment cards and participating banks.
Garmin's ecosystem provides access to additional watch faces, apps and data fields through its supported Connect IQ platform.
Forerunner 165 Music Variant
The standard Forerunner 165 and Forerunner 165 Music are separate variants.
The Music version adds music storage and playback capabilities. Garmin lists up to 7 hours of GPS activity with music playback and up to 6.5 hours using All-Systems GNSS with music.
The Amazon listing supplied for this review should be checked for the exact variant before purchase if music storage is an important requirement.
The standard Forerunner 165 does not have the same onboard music storage feature listed for the Forerunner 165 Music.
Build & Water Resistance
The watch measures approximately 43 × 43 × 11.6mm and weighs about 39 grams.
Garmin uses a fiber-reinforced polymer bezel and a chemically strengthened glass lens.
The Forerunner 165 carries a 5 ATM water rating, making it suitable for swimming and normal water exposure under the manufacturer's specified conditions.
Connectivity & Compatibility
The Forerunner 165 connects with compatible smartphones for notifications, Garmin Connect synchronization and other connected features.
It supports Bluetooth and ANT+ connectivity for compatible sensors and accessories.
The watch uses a proprietary Garmin charging connection.

Final Verdict
A focused GPS running smartwatch with an AMOLED display
The Garmin Forerunner 165 is designed primarily for runners and athletes who want dedicated GPS tracking and structured training features in a relatively lightweight watch.
Its 1.2-inch AMOLED display is a major part of the experience, while built-in GNSS provides independent outdoor tracking. Garmin rates the watch for up to 11 days in smartwatch mode and up to 19 hours of GPS-only activity.
Health features such as wrist-based heart rate, Pulse Ox and sleep score extend the watch beyond running, while Garmin Pay adds a useful everyday smartwatch feature.
The standard Forerunner 165 does not include the onboard music storage of the separate Music version, and it does not offer some of the more advanced features found higher in Garmin's Forerunner range.
For users looking specifically for a running-focused Garmin with an AMOLED screen, built-in GPS, training tools and a lightweight 39g design, the published feature set is clearly centered around that use case.
