Summary

A 46mm GPS running watch with a bright AMOLED touchscreen, multi-band GPS and Garmin’s training platform, aimed at runners who want full metrics without a flagship price. The optical heart-rate sensor is the weak point during hard efforts, so budget for a chest strap if that matters to you.

Strengths

  • Multi-band GPS with SatIQ tracks accurately and is widely praised by testers and owners.
  • The AMOLED touchscreen is bright, sharp and easy to read outdoors.
  • Battery life runs about 13 days in smartwatch mode and 20 hours in GPS mode.
  • Training Readiness and daily suggested workouts are standouts.
  • At 47g it stays light and comfortable for all-day wear.
  • Physical buttons plus touch control work well during a run.

Weaknesses

  • The Elevate V4 optical heart-rate sensor is unreliable during intervals and hard efforts.
  • Firmware updates have caused heart-rate, GPS and battery regressions for some owners.
  • Some owners report battery drain after updates, dropping to days instead of weeks.
  • There is no firmware rollback if an update goes wrong.
  • No full-color topographic maps, only breadcrumb trails and course following.
  • The 46mm case is large for smaller wrists.

Heart rate and the case for a chest strap

The watch uses Garmin’s Elevate V4 optical sensor, the same generation as the Venu series. Testers call it accurate with a snug fit, and TechGearLab measured heart-rate accuracy at 96.55%. Owners tell a different story during hard efforts: intervals, sprints and anything with irregular wrist motion come back wrong often enough that multiple owners report needing a chest strap. Garmin support has said it is investigating the accuracy concerns. A 2026 study found the watch’s HRV estimates unsuitable for research or clinical monitoring, so treat wrist heart rate as a training guide rather than a medical reading.

Battery life and charging

Garmin rates the 265 at up to 13 days in smartwatch mode, 20 hours in GPS mode and 7 hours of GPS with music playing. Testers broadly matched those figures: PCMag saw numbers close to the claims, and Garage Gym Reviews got at least 15 days in smartwatch mode. Real-world life tracks how much GPS, music and always-on display you ask of it. Charging uses Garmin’s four-pin connector and a USB-C cable, and a full charge takes roughly an hour.

Firmware updates and reliability

Garmin pushes firmware through Garmin Express and Garmin Connect, and some releases have gone badly. Owners list heart-rate accuracy loss, GPS trouble, battery drain and Training Readiness stalling after specific updates (17.xx, 18.22, 18.23 and 27.09). One owner described a battery that died after a month; others saw smartwatch life fall to three days instead of 13. Garmin offers no rollback, so a bad update has to be waited out. These reports come from a subset of users, but if you depend on the watch for training data, updates are not risk-free.

Is it worth it?

Garmin sells the 265 direct at $449.99, and Best Buy lists it at the same figure (Garmin, Best Buy, 2026). The watch launched at $449.99 in March 2023 and has held that price at Garmin direct, though third-party and refurbished units turn up lower: BuyDig listed an Aqua/Black bundle at $364.99, Garmin UK showed £369.99 (down from £429.99) and Garmin Canada $659.99 CAD (down from $829.99 CAD). The only recurring cost most owners face is a spare 22mm QuickFit band at $39.99 from Garmin; the Garmin Connect+ subscription is optional and core features work without it.

If you want Garmin’s training platform and a bright AMOLED screen and you run with a chest strap, the 265 is easy to justify at sale or refurbished prices. If you need full topographic maps, watch for the 955 or 965 instead: the 265 offers breadcrumb trails and course following but no full-color maps. As a general smartwatch it is a compromise, since notifications are basic next to an Apple Watch or a Wear OS watch. And check your wrist: the 46mm case is a lot of watch, and testers scored wearability poorly for smaller arms.

Which model this is

This page covers the Forerunner 265 in the Whitestone/Tidal Blue colorway, part number 010-02810-01, with the 46mm case. It was released in March 2023 as the successor to the Forerunner 255 and has since been followed by the Forerunner 570. Garmin also sells the smaller 265S at 42mm with a different model number and slightly different specs, so check the number before you compare. The Amazon listing for this color is ASIN B0BS1T7G8S.
