Samsung Galaxy Watch9 40mm Smartwatch, Graphite

The Samsung Galaxy Watch9 40mm in Graphite is a smartwatch designed exclusively for Android devices. It runs on the Snapdragon Wear Elite Platform and Wear OS, providing access to the Google Gemini assistant and tracking daily activity. The watch features a 1.3-inch Super AMOLED always-on touchscreen with a peak brightness of 3000 cd/m². It includes 32 GB of internal storage. The watch does not have cellular connectivity, relying instead on Bluetooth 6.0, Wi-Fi, and NFC for data synchronisation and contactless payments.

The 40.4 mm case comes with a removable Graphite silicone band. An integrated accelerometer, gyroscope, electronic compass, and altimeter track movement across various sports modes, while a built-in barometer monitors atmospheric pressure changes during elevation-based activities. The watch tracks sleep quality, steps, and calorie expenditure based on user-defined goals. Built-in microphones, speakers, and a haptic engine provide audio prompts and alerts for notifications.
