Samsung Galaxy Watch 8 40mm LTE Smartwatch - Graphite

The Samsung Galaxy Watch 8 40mm LTE in Graphite is Samsung's 2025 everyday smartwatch, with a cushion design that is just 8.6 mm thick and an Armor Aluminum case weighing 30.0 g. The 3.4 cm Super AMOLED display (438 x 438 pixels) reaches up to 3,000 nits under sapphire glass, and the watch is rated 5 ATM and IP68 and tested to MIL-STD-810H.

A 3nm five-core processor with 2GB of RAM and 32GB of storage runs One UI 8 Watch with Google Gemini built in. Dual-band GPS (L1+L5) tracks runs accurately, and Running Coach builds a plan from a running test. Samsung Health adds Bedtime Guidance, Vascular Load, the Antioxidant Index, Energy Score, ECG, blood pressure and body composition, with fall detection and SOS for emergencies. The eSIM lets you take calls and stream music without your phone.

Samsung rates the 325 mAh battery at up to 40 hours with Always On Display off and up to 30 hours with it on. The watch works with Android 12 or later, and ECG and blood pressure need a Samsung Galaxy phone. It suits swimming but not diving or high-pressure water sports, and LTE needs a carrier that supports watch eSIMs.

Charge the watch on the wireless charger first. On your Android phone, install or update the Galaxy Wearable app, turn on Bluetooth and follow the pairing steps in the app. To use LTE, add a watch eSIM plan from your carrier during setup or later in the Galaxy Wearable app.

Galaxy Watch 8 with its band fitted and a wireless charger with a USB-C connector. A power adapter is sold separately.

Samsung India covers this watch with a 12-month manufacturer warranty from the date of purchase. Keep your invoice for any service request at a Samsung service centre.
