Garmin Forerunner 265 (46 mm) review 2027

What problem does the Garmin Forerunner 265 solve for runners and cyclists?

The Forerunner 265 is built for people who train, and its case rests on accuracy and battery life rather than on being a phone on the wrist. In our test it recorded the most accurate GPS of the group, with dual-band positioning holding the line under trees and buildings, and it pairs that with training load, readiness and race predictor metrics that runners actually use. It works with any phone and stores music, so it is not tied to one ecosystem. Measured battery life was 11 days with daily GPS runs, which means charging is a weekly habit rather than a nightly one. The trade-off is deliberate: as a smartwatch it sits a generation behind Apple and Samsung, and it does not try to be one.

How did we score the Garmin Forerunner 265?

We scored it across five criteria. Health and fitness accuracy carries the most weight at 30 points, and it took 29 of them: heart rate was measured against a chest strap on runs and intervals, GPS distance against a reference on a measured 5K, and sleep staging consistency was checked, along with ECG and SpO2 where offered. Battery is worth 20 points and it earned 18, measured in days per charge with always-on display and a daily 30-minute GPS workout. Smart features and ecosystem is also worth 20, and there it took 12, covering notifications and replies, payments, apps, calls, phone compatibility and safety features. Design and display is worth 10 and it scored 8, judged on screen brightness and readability outdoors, size options, materials, water rating and comfort in sleep. Value is worth 20 and it scored 12, based on price and any subscription needed for headline features. That adds up to 7.9 overall.

Where the Forerunner 265 stands out

Two measured results define this watch. The first is GPS: dual-band held the line under trees and buildings, the most accurate in the test. The second is heart rate, where the error against a chest strap was 1.8 bpm across runs and intervals. Battery came in at 11 days measured with daily GPS runs, so a training week plus a weekend away does not require a charger. On top of the measurements, the training load, readiness and race predictor tools are the ones runners keep open, and the watch works with any phone while storing music for runs without a handset.

How multi-band GNSS and AMOLED work

Multi-band GNSS means the watch listens on more than one radio frequency for satellite signals. A single frequency can bounce off buildings and trees before reaching the watch, which shifts the position it calculates; a second frequency gives the receiver a cleaner reference to compare against, so the track stays on the road or trail. AMOLED is a display technology in which each pixel emits its own light, so black pixels are simply off. That produces deep blacks and high brightness without a backlight washing the whole panel, which is why AMOLED screens stay readable in direct sun and can dim very low at night.

What is the Forerunner 265 made of, and what does it include?

The spec sheet covers nine rows. It works with iPhone and Android. Measured battery is 11 days. GPS is multi-band GNSS. There is no ECG and no LTE option. Water rating is 5 ATM. The display is AMOLED, and it comes in 42 mm and 46 mm sizes. No subscription is required for headline features, though Garmin Connect+ is optional.

How does the Forerunner 265 compare with its rivals?

The Garmin Venu 3 costs the same $449.99 and scores 7.9, matching the Forerunner on price and score; it offers ECG in select regions, calls from the wrist and 12 days measured, but has fewer running metrics and no LTE. The Amazfit Balance is $229.99 and scores 7.8, with dual-band GPS, 13 days measured and an AMOLED screen, but no ECG and a single 46 mm size. The OnePlus Watch 3 at $329.99 scores 7.7 with dual-band GPS, ECG, sapphire AMOLED and 5 days measured, but it is Android only. The Samsung Galaxy Watch 7 at $329.99 also scores 7.7, with dual-band GPS, ECG on Samsung phones, an LTE option and 1.5 days measured, and it is best with a Samsung phone.

Where the Forerunner 265 falls short

Smart features are where it lost ground, and the score reflects that: 12 out of 20. Notifications are basic, with no replies on iPhone and no third-party apps to speak of. There is no ECG. The case is plastic at $450, which is a fair criticism at this price. If wrist-based messaging, payments and app breadth matter more than training data, the Apple and Samsung watches are the ones to look at.

Is the Garmin Forerunner 265 good value at $449.99?

The price is $449.99, and value scored 12 out of 20. No subscription is needed for the headline features, though Connect+ is optional. The Venu 3 costs the same, while the Amazfit Balance undercuts it at $229.99 and the OnePlus Watch 3 and Galaxy Watch 7 sit at $329.99.

Who should buy the Garmin Forerunner 265?

Runners and cyclists. If your priority is accurate GPS, heart-rate data you can trust at 1.8 bpm error against a strap, training load, readiness and race prediction, and 11 days of measured battery, this is the watch to get. If you want a phone on your wrist first, it is not.
