Garmin fēnix 9 Pro – 51mm Premium Multisport GPS Smartwatch

Built for serious athletes and outdoor adventurers who want the biggest display and longest battery life in the AMOLED fēnix 9 Pro family, the Garmin fēnix 9 Pro – 51mm combines a lightweight titanium construction with advanced training, comprehensive mapping and a huge 1.5-inch AMOLED display.

This Carbon Gray DLC Titanium with Black/Pebble Gray Silicone Band edition features a scratch-resistant sapphire lens, rugged titanium case, integrated LED flashlight and up to 31 days of battery life in smartwatch mode.

Garmin's Largest fēnix Display

The 51mm fēnix 9 Pro features Garmin's largest-ever display on a fēnix smartwatch — a 1.5-inch AMOLED display capable of reaching up to 3,000 nits of brightness.

That extra screen space makes maps, performance data and everyday smartwatch functions easier to view at a glance, particularly during outdoor activities. A scratch-resistant sapphire lens protects the display, while the titanium case keeps the watch strong without unnecessary weight.

Built for Serious Training

Access more than 100 activity profiles together with Garmin's advanced training and performance tools.

Training Readiness considers factors including sleep quality, recovery and training load to help determine whether you're ready for another demanding workout. Training Status provides insight into whether your training is productive, peaking or strained, while enhanced Stamina Metrics help visualise how your endurance is changing over time.

Additional tools include VO2 max, Endurance Score, Hill Score, recovery time, Visual Race Predictor, PacePro, ClimbPro, wrist-based running dynamics and adaptive Garmin Coach plans.

Made for Multisport Athletes

Whether you're running, cycling, swimming or combining multiple disciplines, fēnix 9 Pro is designed to follow.

Dedicated profiles support triathlons, duathlons, brick workouts and swim/runs, while downloadable workouts cover strength, HIIT, cardio, yoga, Pilates and mobility. You'll also find specialised features for skiing, snowboarding, surfing, mountain biking, rowing, rucking and more.

The watch is also rated for recreational scuba and apnea diving to 40 metres, supported by leakproof metal buttons.

Advanced Maps & Navigation

Take your adventures further with multicontinent TopoActive maps and a comprehensive range of navigation features.

Dynamic Round-Trip Routing lets you enter how far you want to travel and generates a suggested route back to your starting point. If you move off course, the watch can automatically map a new route while targeting the same planned mileage.

You'll also have SatIQ technology, NextFork, Up Ahead, ABC sensors, turn-by-turn directions, SkiView maps and more than 43,000 preloaded golf course maps.

Integrated LED Flashlight

A built-in LED flashlight gives you convenient illumination directly from your wrist.

Choose between dimmable white, red or green light, making it useful for running before sunrise, navigating after dark, camping or everyday situations where you need quick access to a light.

Built-In Speaker & Microphone

When paired with a compatible smartphone, the fēnix 9 Pro lets you make and receive calls directly from your wrist.

The built-in speaker and microphone also let you record voice notes and interact with your smartphone's voice assistant.

24/7 Health & Recovery Insights

Training effectively also means knowing when to recover.

The fēnix 9 Pro provides continuous health and wellness insights, including HRV Status for understanding recovery trends. Sleep Coach provides personalised recommendations to help improve sleep and prepare your body for upcoming activities.

Garmin Epic

With Garmin Epic, you can turn a multi-day adventure into one complete story.

Combine several days of activities with photos, health information and performance statistics in Garmin Connect — ideal for documenting races, hiking expeditions, cycling tours and longer adventures.
