Garmin Forerunner 165 - Mist grey/Whitestone arrives as a versatile smartwatch designed for everyday athletes and tech-savvy users who want performance and style in one device.

The Forerunner 165 features a crisp 1.2" (3.05 cm) AMOLED colour touchscreen with a 390 x 390 pixel resolution and a 30.4 x 30.4 mm display area, offering vivid readability whether you are outdoors or in low light thanks to its ambient light sensor.

Built on a 43 mm polymer case in a subtle grey with a white silicone band, the round watch measures 43 x 43 mm with a thickness of 1.16 cm and weighs only 39 g, making it comfortable for all-day wear across a wrist range of 126–203 mm. The single prong strap buckle in silver secures the band for active use.

The watch is engineered for sport and health tracking: it includes an optical heart rate monitor, blood oxygen (SpO2) sensor, accelerometer, barometric altimeter, electronic compass, thermometer and stress monitoring. Activity tracking covers distance, calories burned and dedicated apps for running, cycling and swimming via Connect IQ.

Connectivity supports Android and iOS phones with Bluetooth and ANT+ for external sensors, integrated multiple satellite systems (GPS, GLONASS, Galileo) for precise positioning, and a mobile network connection for on-the-go features. It also offers smart notifications, calendar alerts, music controls and a Find My Phone function.

With robust protection, the Forerunner 165 is water resistant to 5 ATM, suitable for swimming and daily water exposure. The built-in rechargeable battery delivers up to 11 days in smartwatch mode and around 19 hours in GPS mode, and it ships with a USB Type-C cable and charger for quick recharging.

Typical use cases include training runs where accurate GPS and heart rate metrics matter, cycling rides paired with external sensors via ANT+, and multi-day activity tracking for outdoor adventures that benefit from barometer and altimeter readings. The watch’s lightweight build and comprehensive sensors also make it a solid companion for everyday health monitoring and productivity with PIM features like alarm clock, calendar, stopwatch and timers.

Key selling points: AMOLED 1.2" touchscreen, advanced health sensors (HR & SpO2), multi-GNSS positioning, 5 ATM water resistance, 11-day battery life, and lightweight 39 g design—ideal for athletes and active users seeking reliable performance and stylish wear.
