Garmin Forerunner 255: a smartwatch still performing strongly in 2026

The Garmin Forerunner 255 is a multisport smartwatch aimed at athletes seeking advanced training monitoring without moving up to the brand's most expensive models. This standard 46 mm version weighs just 49 g and features a 1.3-inch colour transflective MIP display with a 260 x 260-pixel resolution. Its key advantage is that it remains fully legible in bright sunlight while using far less power than an AMOLED panel. The device also combines a fibre-reinforced polymer case with Corning Gorilla Glass 3 to protect the display.

Advanced sports tracking and training insights

For sport features, the Forerunner 255 includes more than 30 activity profiles, covering road running, trail running, triathlon, cycling, swimming, HIIT, rowing and skiing. The smartwatch delivers advanced metrics such as VO2 Max, heart rate variability (HRV), recovery time, running power, daily workout suggestions and race performance predictions. In addition, its morning report automatically brings together sleep data, recovery information and that day's training guidance as soon as you wake up.

The Forerunner 255 also has a multi-band GPS system compatible with GPS, GLONASS, Galileo and QZSS, alongside SatIQ technology, which automatically balances accuracy and battery life. Garmin's model offers up to 14 days of battery life in smartwatch mode and around 30 hours using standard GPS. It further includes a barometric altimeter, gyroscope, electronic compass, SpO2 sensor and the latest-generation Garmin Elevate heart-rate monitor. With its 5 ATM rating, the device can be used for swimming and open-water training at depths of up to 50 metres without risk.

Garmin Forerunner 255 connectivity, health features and battery life

The connected side of the Forerunner 255 covers smartphone notifications, Garmin Pay mobile payments, Garmin Connect synchronisation, ANT+ and Bluetooth compatibility, plus music controls for your phone. For wellbeing and everyday functions, Garmin focuses on health tracking, including sleep analysis, stress, breathing, Body Battery and menstrual cycle tracking.

Thanks to its full range of features and a design that is as attractive as it is robust, the Forerunner 255 remains highly regarded for its excellent balance of performance and battery life, even several years after launch. This smartwatch benefits from very accurate GPS, dependable heart-rate tracking and, above all, endurance that comfortably exceeds that of competing models. At a price below €165, this model becomes an unmissable option, so it is best to act quickly before it sells out.
