Marine Smartwatch with Health Features and More!
Engineered for life on the water, the Garmin Quatix® 8 is a rugged, high-performance marine smartwatch built to enhance every boating, fishing, and outdoor adventure. Featuring a large 1.4” AMOLED touchscreen with ultra-clear visuals, it’s protected by sapphire crystal and wrapped in a 51mm titanium bezel for durability in harsh marine environments. With a 10 ATM water rating (100 meters) and extended battery life of up to 16 days in smartwatch mode, it's ready for long days on the water.
Designed with advanced marine technology, the Quatix 8 comes preloaded with features that make boating smarter and safer. The Anchor Drag Alarm lets you set a custom drift radius and view a real-time map display, so you can anchor with confidence. Fish Forecast uses celestial data and your location to recommend the best days and times to fish, giving you a strategic edge out on the water.
Take full control of your marine setup with voice-enabled helm control, thanks to a built-in microphone and speaker. Use Bluetooth® connectivity to control compatible Garmin chartplotters, autopilots, Force® trolling motors, Fusion® marine stereos, and more—right from your wrist. Whether you're navigating open seas or trolling your favorite inland lake, this watch keeps you connected to your vessel.
Navigate with precision using multi-band GPS and SatIQ™ technology, which automatically optimizes accuracy and battery life. Paired with an altimeter, barometer, and 3-axis electronic compass, the Quatix 8 helps you confidently explore on and off the water. It also comes with TopoActive maps with relief shading, and supports optional BlueChart® g3 coastal charts and LakeVü™ g3 inland maps for comprehensive on-screen navigation.
Beyond marine tools, this smartwatch offers powerful everyday features. Stay connected with smart notifications, Garmin Pay™, and on-device music storage (including Spotify® and Amazon Music). Track your health and performance with wrist-based heart rate monitoring, Pulse Ox, sleep tracking, stress tracking, and more. Plus, it supports multiple activity profiles like sailing, paddleboarding, strength training, and swimming.
The Garmin Quatix 8 is more than a marine tool—it’s your all-in-one command center for adventure, wellness, and navigation. Whether you're charting new waters, casting lines, or enjoying a sunset at anchor, this watch delivers the performance and reliability Garmin is known for.
