Garmin Quatix 8 Marine GPS Smartwatch

They share the same hardware platform — the Quatix 8 is the marine edition. On top of everything the Fenix 8 does (multisport training, maps, health tracking), the Quatix 8 adds dedicated boating features: autopilot control with a compatible Garmin chartplotter or GHC 50, boat data streaming from compatible chartplotters, sail racing assistance with tack assist and regatta timer, anchor drag and tide-change alarms, and remote control of Garmin trolling motors and Fusion stereos. If you spend time on the water, the Quatix 8 is the one built for you.

The Quatix 8's headline upgrade over the 7 series is the built-in speaker and microphone — take calls, use voice commands, and control a compatible chartplotter by voice from the wrist. Beyond that, the bright AMOLED display and LED flashlight are now standard on every model (previously only the higher-end Quatix 7 variants had them), on Garmin's newest sensor platform. If you own a base Quatix 7, the jump is significant; from a 7 Pro or Sapphire it is more incremental unless the voice features appeal to you.

The Quatix 8 comes in 47mm and 51mm case sizes. Both use Garmin's QuickFit band system — 22mm bands for the 47mm case and 26mm bands for the 51mm case — so you can swap between the included band and any compatible QuickFit strap without tools.

Yes — more than most people expect. The Quatix 8 is dive-rated to 40 meters (EN 13319) with leakproof buttons and includes scuba and apnea activity profiles with a genuine Buhlmann decompression model, so it handles snorkeling, freediving, and single-gas recreational scuba within 40 meters. For air integration with the T2 transceiver, multi-gas or technical diving, a 200-meter rating, and SubWave features, step up to Garmin's dedicated Descent series.

Yes, and it is standard on every Quatix 8 model. On the Quatix 7 series a built-in LED flashlight was reserved for the higher-end variants, so this is one of the clearest upgrades in the new generation. It is genuinely useful on a boat at night or rigging gear before a dawn dive.

Yes. The built-in speaker and microphone are the Quatix 8's headline upgrade over the Quatix 7 series, letting you take calls, use voice commands, and control a compatible Garmin chartplotter by voice straight from your wrist. On a boat, hands-free chartplotter control is the feature that actually changes how you use the watch.

Yes, within the Garmin marine ecosystem. The Quatix 8 gives you autopilot control with a compatible Garmin chartplotter or GHC 50, streams boat data from compatible chartplotters, and remotely controls Garmin trolling motors and Fusion stereos. You can also drive a compatible chartplotter by voice through the watch's microphone. All of it depends on having compatible Garmin marine electronics on board.

Yes. The Quatix 8 includes sail racing assistance with tack assist and a regatta timer, plus boat data streaming from compatible Garmin chartplotters. Those racing tools are part of what separates the Quatix from the otherwise identical Fenix 8 hardware.

Yes. The Quatix 8 has a dedicated anchor drag alarm, along with a tide-change alarm, as part of its marine feature set. They are the kind of small, boat-specific alerts you do not get on a Fenix 8, and they are a big reason boaters pick the marine edition.

Yes. The Quatix 8 is built on the same hardware platform as the Fenix 8 and does everything the Fenix 8 does, including multisport training, onboard maps, health tracking, music, Garmin Pay, and the full golf feature set, then layers the marine features on top. Nothing is removed to make room for the boating tools.

No. Every Quatix 8 model ships with the bright AMOLED display, which is now standard across the range along with the LED flashlight. If you specifically want a solar-charging display for maximum time between charges, that option lives in the Fenix 8 line, which offers Solar variants in 47mm and 51mm.

Every quatix 8 has a built-in speaker and microphone, so the 47 mm and 51 mm AMOLED models can make and take calls when paired with a compatible smartphone. The quatix 8 Pro goes further with built-in inReach technology for LTE and satellite connectivity, which allows messaging and LiveTrack location sharing away from a phone. LTE and satellite service requires a subscription and coverage varies.

The quatix 8 Pro, offered in 47 mm, adds built-in inReach technology for satellite and LTE connectivity, with messaging, LiveTrack sharing and interactive SOS through the Garmin 24/7 Response center up to 50 miles offshore (subscription required). The standard quatix 8, in 47 mm and 51 mm, shares the same 1.4-inch AMOLED display, titanium bezel, sapphire lens, leakproof metal buttons and 40 m dive rating, but has no satellite or LTE connectivity.

In smartwatch mode, Garmin rates the 47 mm quatix 8 Pro at up to 15 days, the 47 mm quatix 8 at up to 16 days and the 51 mm quatix 8 at up to 29 days. All models use a built-in rechargeable lithium-ion battery. Charge the watch between 0 and 45 C (32 to 113 F) for best results.

That option bundles the 47 mm quatix 8 Pro with a Garmin Voice Control Cable. The watch itself ships with a charging/data cable and documentation.
