Galaxy Watch8 (4.4cm) Review: The Sleek AI Health Companion
The new Galaxy Watch8 (4.4cm) represents the pinnacle of Samsung’s design philosophy, fusing its thinnest, most comfortable form factor with a powerful layer of artificial intelligence. As of September 2025, it’s driven by a powerful 3nm processor that brings Galaxy AI to your wrist. This intelligence unlocks proactive coaching for sleep and fitness, an ultra-bright 3000-nit Super AMOLED display, and revolutionary new health sensors. Starting from ₹35,999.00, the Galaxy Watch8 is the new benchmark for a sleek, intelligent health companion.
1. Ultra-Slim Design & Display Excellence
Thinnest Galaxy Watch Ever
The Watch8 is the slimmest Galaxy Watch yet, measuring just 8.6mm thick. Its reimagined cushion design and lightweight Armor Aluminum frame provide unparalleled comfort for 24/7 wear.
Dynamic Lug System
A new Dynamic Lug System integrates the band seamlessly, allowing for a more snug and stable fit. This enhances comfort and improves the accuracy of health sensors.
3000-Nit Super AMOLED Display
The display is a major highlight, featuring a peak outdoor brightness of 3,000 nits. This makes the large 3.73 cm (1.5″) Super AMOLED screen exceptionally clear and readable even in direct sunlight.
2. AI-Powered Performance & Coaching
Efficient 3nm Processor
At its core is a new Penta-Core 3nm chip that delivers faster processing and greater power efficiency, ensuring every interaction is fluid and responsive.
Galaxy AI & Gemini
Galaxy AI provides proactive coaching for sleep and fitness, while integrated Google Gemini allows you to get answers, manage tasks, and access information with your voice.
Proactive Health Coaching
The watch learns your habits to provide personalized guidance. The Bedtime Guidance feature suggests optimal sleep times, and the Running Coach creates tailored training plans.
3. Next-Generation Health Suite
Antioxidant Index
A world-first feature that uses the BioActive Sensor to measure carotenoid levels in your skin, offering a unique estimation of your body’s antioxidant capacity and diet quality.
Vascular Load & Energy Score
The watch monitors cardiovascular stress during sleep (Vascular Load) and generates a daily Energy Score to help you plan your activities.
Core Health Monitoring
Includes a full suite of vital sensors for ECG, Blood Pressure, Body Composition (BIA), and SpO2. It also features Irregular Heart Rhythm Notifications (IHRN) for proactive heart health awareness.

Pros & Cons at a Glance
The exceptionally thin 8.6mm profile makes it one of the most comfortable smartwatches for 24/7 wear.
Tools like the Antioxidant Index and AI Energy Score offer unique health insights unavailable elsewhere.
A peak brightness of 3,000 nits ensures the screen is perfectly readable even in direct sunlight.
Lacks the Titanium case and 10ATM water resistance of the Ultra model, making it less suitable for extreme sports.
The 40-hour battery is sufficient for daily use and sleep tracking but falls short of the Ultra’s multi-day endurance.
Final Verdict
The Galaxy Watch8 (4.4cm) masterfully balances cutting-edge technology with everyday wearability. It packs nearly all the revolutionary AI and health features of its larger siblings into Samsung’s slimmest and most comfortable design yet. For the user who wants a powerful health companion that excels in daily life, fitness, and professional settings without the bulk of a ruggedized watch, the Galaxy Watch8 is the clear and intelligent choice. It’s the perfect blend of style, comfort, and next-generation smarts.
