Garmin quatix® 8 AMOLED Marine GPS Smartwatch
The quatix 8 is Garmin’s flagship marine smartwatch — built on the fēnix 8 platform with dedicated marine features including chartplotter voice control, boat data streaming, helm remote, and sailing race tools. Available in 47mm ($1,199.99) and 51mm ($1,299.99) with a 1.4-inch AMOLED display, sapphire lens, titanium bezel, built-in speaker and mic, LED flashlight, multi-band GPS, ECG, and up to 29 days of battery life.
Our Take: The quatix 8 is the marine smartwatch for people who actually use their boat electronics. Chartplotter voice control, boat data streaming, autopilot remote, Fusion stereo control, and trolling motor remote — all from your wrist. The built-in speaker and mic (new vs quatix 7) means you can take phone calls and bark chartplotter commands without reaching for the helm. The 1.4-inch AMOLED is gorgeous and sunlight-readable, the sapphire lens handles salt spray without scratching, and the 40m dive rating with leakproof buttons means you can jump in without thinking twice. Off the water, it’s a full fēnix 8: multi-band GPS, ECG, Body Battery, Sleep Coach, 100+ sport profiles, music, Garmin Pay. The only reason to step up to the quatix 8 Pro is if you need satellite messaging and SOS via inReach without your phone.
Why you’d choose this model
- Control your compatible Garmin chartplotter with voice commands via Bluetooth. Make and take phone calls when paired with your smartphone. Use your phone’s voice assistant to respond to texts from your wrist.
- See speed, depth, wind, heading, and engine data streamed from compatible Garmin marine electronics right on your wrist. Remote control chartplotters, autopilots, Fusion stereos, and Force trolling motors.
- A vivid 454×454 AMOLED display protected by scratch-resistant sapphire crystal and framed by a durable titanium bezel. Always-on mode available. Excellent readability in direct sunlight on the water.
- Water-rated to 100 meters with a 40-meter dive rating. Leakproof metal buttons and a metal sensor guard protect internals during scuba and apnea dive activities.
- Multi-band GNSS (L1 + L5) with SatIQ technology provides the best position accuracy Garmin offers — critical for offshore navigation, waypoint marking, and returning to fishing spots.
- A true integrated LED flashlight with adjustable intensity and a red light mode for preserving night vision at the helm. Activated with a double-tap of the top button.
- The 51mm model delivers up to 29 days in smartwatch mode and 84 hours in GPS. The 47mm model offers 16 days smartwatch and 42 hours GPS. Both dramatically outlast any competing marine smartwatch.
- Gen 5 HR sensor with ECG for atrial fibrillation detection. Body Battery energy monitoring, HRV Status, Sleep Coach, nap detection, Pulse Ox, stress tracking, and Jet Lag Advisor.

Who this watch is perfect for
- Boat owners who want wrist-based helm control — chartplotter, autopilot, Fusion stereo, trolling motor — without walking back to the console.
- Sailors who want tack assist, race start guidance, regatta timer, and anchor/tide alerts on their wrist.
- Anglers who want to mark waypoints, stream depth/fish data, and control Force trolling motors from anywhere on the boat.
- Active mariners who also run, cycle, swim, and train on land and want a single watch that does everything.
You may prefer a different Garmin if…
- You need satellite messaging and SOS without your phone — the quatix 8 Pro adds inReach satellite + LTE connectivity.
- You don’t need marine features and want the same platform for less — the fēnix 8 AMOLED shares the same core hardware at ~$100 less.
- You want a marine watch at a lower price and don’t need AMOLED, speaker/mic, or dive rating — the quatix 7 is a capable previous-gen option.

What is the difference between the quatix 8 and the quatix 8 Pro?
