The Galaxy Watch FE blends premium design with robust health and connectivity features. Housed in a 40 mm aluminum case and offered in Black, Pink Gold, and Silver finishes, it weighs just 26.6 g and measures 39.3 × 40.4 × 9.8 mm. Its 1.2-inch Super AMOLED display offers a crisp 396 × 396 pixel resolution, includes always-on display functionality, and is protected under sapphire-crystal glass for durability.

Under the hood, the Watch FE is powered by Samsung’s Exynos W920 dual-core processor clocked at 1.18 GHz, along with 1.5 GB of RAM and 16 GB of internal storage. It runs Wear OS (branded as “Wear OS Powered by Samsung”) with the One UI Watch 5 interface, enabling seamless compatibility with Android phones (Android 11 +).

Connectivity and sensors are comprehensive: you get Bluetooth (version 5.x), WiFi (2.4 GHz & 5 GHz), NFC for payments, GPS (with support for GLONASS, Beidou, Galileo), and in some models LTE/eSIM support. Health and fitness tracking is front and center: the watch includes a BioActive sensor that combines optical heart rate, electrical heart (ECG) measurement, and bioelectrical impedance analysis (BIA) for body composition tracking—alongside accelerometer, gyroscope, barometer, ambient light sensor and more. The build is also rated for durability: 5 ATM water resistance, IP68 dust & water ingress protection, and MIL-STD-810H standard compliance for ruggedness.

Battery capacity is 247 mAh with wireless charging support, and while this is modest compared to some larger watch models, it enables everyday use and integrates well with the compact design. Additionally, those heavily invested in the broader Samsung ecosystem will appreciate features like remote camera control for their phone, seamless “Find My Phone” integration, mobile wallet payments via Samsung Wallet, and smart pairing/interaction with Galaxy phones.

Color and variant note: All three color variants—Black, Pink Gold, and Silver—share identical core specifications. The differences are purely cosmetic (case color and strap combinations), so your selection can be based on personal style preference rather than technical capability.
