For those who live part of their life on the water — and the rest chasing adventure — Garmin Quatix 8 latest marine smartwatch, might just be the most complete wrist companion yet.
If you’re familiar with Garmin’s Quatix series, you already know it’s essentially the Fenix line, reimagined for boaters.
What makes the Quatix 8 stand out isn’t just a feature checklist — it’s how seamlessly it blends high-performance training tools with advanced marine tech.
Whether you’re steering a yacht, casting off on a weekend sail, or just love the maritime aesthetic, this watch is designed with you in mind.

A Familiar Look, with Smarter Muscle
Design-wise, the Garmin Quatix 8 isn’t trying to reinvent the wheel — and that’s a good thing.
Garmin has stuck with the rugged, tested design that Fenix fans love: a durable body, tactile buttons, and subtle nautical accents (hello, ocean blue trim).
Sizes confirmed so far include 47mm and 51mm, offering flexibility depending on your wrist and preference.
But the real magic starts with its stunning 1.4-inch AMOLED display. This vibrant, crisp screen makes marine charts pop and daily stats incredibly clear, even in direct sunlight. And that’s just the beginning of the smarter muscle under the hood.
Built on Fenix 8 DNA — With a Marine Upgrade
Garmin gave the Quatix 8 the same high-end hardware you’ll find in the Fenix 8 and Tactix 8 — so you’re getting all the latest tech under the hood, including:
✅ Elevate Gen 5 Heart Sensor
If you track heart rate seriously — especially during intense activity — this is Garmin’s best sensor yet. It’s more accurate in motion, during sweat-heavy workouts, and even underwater.
📞 Mic & Speaker? Yes, Really.
The phone call on your wrist? Yep. But here’s where it gets interesting — you can now control your Garmin chart plotter using voice commands. That means adjusting your heading or triggering functions without letting go of the helm. Pretty slick.
🤿 Upgraded Dive Rating
Now dive-rated to 40 meters, the Quatix 8 doesn’t just dip its toes in. It fully embraces both scuba and freediving features. Plus, those metal buttons? Leakproof and dive-ready.
🔦 LED Flashlight Built In
This one surprised me: a flashlight on your watch sounds minor — until you need it. Whether you’re checking lines before sunrise or navigating below deck at night, it’s incredibly practical. There’s even a red light mode for preserving night vision.
Quatix 8 Battery Life
The Garmin Quatix 8 offers impressive battery life to match any adventure. In standard smartwatch mode, expect up to 16 days (or 7 days with the always-on display). For extended periods, Battery Saver Watch Mode stretches this to 23 days.
When using GPS Only, it lasts up to 47 hours (37 hours always-on). For more robust tracking, All Satellite Systems provides up to 38 hours (30 hours always-on), while Multi-band tracking offers 35 hours (28 hours always-on)*.
If you add music, you’ll still get up to 10 hours. For truly epic journeys, Max Battery GPS extends to 81 hours, and Expedition GPS can last up to 17 days.
This versatile power ensures your Quatix 8 is ready for any journey, from daily wear to multi-week explorations.
Designed for Life on the Water
This is where the Garmin Quatix 8 truly pulls ahead, leveraging Garmin’s software evolution for unparalleled marine capabilities.
It’s not just a Fenix in a sailor’s suit — it’s a genuine, indispensable tool for water-based adventure, with features like:
