Samsung Galaxy Watch8 40mm LTE

Samsung Galaxy Watch8 40mm (LTE)

The thinnest Galaxy Watch Samsung has made, and a genuine redesign rather than an iteration. The Watch8 moves to a squircle case at just 8.6mm thick and 30g, with a new cushion design and the Dynamic Lug System for a closer, more comfortable fit on the wrist.

The 1.3-inch Super AMOLED display runs at 438×438 behind sapphire crystal and reaches 3,000 nits peak brightness — a substantial jump that makes it genuinely readable in direct sunlight. Underneath sits the 3nm Exynos W1000, with 2GB RAM and 32GB storage running Wear OS 6 with One UI 8 Watch.

The LTE model is the key distinction here. With an eSIM you can make calls, send messages, stream music and receive notifications with your phone nowhere nearby — useful for running, cycling or anywhere you’d rather not carry a handset. It pairs to your existing number through your carrier’s plan sharing.

Health tracking is comprehensive: heart rate, ECG, blood oxygen, skin temperature, sleep tracking with bedtime guidance, and automatic stress monitoring with alerts and guided breathing. The Watch8 adds the Antioxidant Index and an Advanced Glycation End-products reading for metabolic trend tracking, plus proactive coaching across sleep, running and general health. Galaxy AI features run throughout, with Gemini available on-watch.
