Honestly, most people buying a smartwatch are just looking for a tiny phone on their wrist. They want the notifications. They want the pretty OLED screen. They want to reply to a text while standing in line at a grocery store. But if you’ve ever tried to use a standard "lifestyle" smartwatch to track a 20-mile trail run in the deep woods, you know exactly where the wheels fall off. It’s the battery life. It’s the GPS drift. It’s the fact that touchscreens hate sweat. That is precisely why the Garmin watch with GPS remains the gold standard for anyone who actually cares about the integrity of their movement data.
GPS is hard. People forget that. Your watch is communicating with a satellite 12,000 miles away while you are moving, sweating, and likely under a canopy of trees. Garmin has been doing this since before most of us had cell phones.
The multi-band frequency obsession
You’ve probably heard the term "Multi-band GNSS" or "L1 + L5" tossed around in gear reviews. It sounds like marketing fluff. It isn't. Traditional GPS watches used a single frequency, which is fine if you're standing in the middle of a literal desert. But the moment you enter a "city canyon" (think NYC or Chicago) or a dense forest, those signals bounce off buildings and rock faces. This creates "multipath interference." Your watch thinks you’re running through a brick wall or hovering over a river.

Garmin’s higher-end units, like the Epix Pro or the Fenix 7 Pro, utilize SatIQ technology. This is actually pretty clever. Instead of draining your battery by constantly hunting for every available satellite, the watch toggles between GPS modes based on your environment. If you're in an open field, it sips power. If you hit a technical trail under heavy cover, it ramps up the accuracy.
It’s about reliability. You don't want to finish a marathon and see 25.8 miles on your wrist. That’s heartbreaking.
Why physical buttons actually matter
I’ve used plenty of watches with beautiful, responsive touchscreens. They are great for scrolling through Spotify. They are absolute garbage when your hands are wet, you’re wearing gloves, or you’re pushing through a high-intensity interval session. Garmin keeps the five-button layout for a reason. You can operate a Garmin watch with GPS without ever looking at the screen. You feel the "click." You know you’ve lapped your run. You know you’ve paused the workout.
The screen technology is another weirdly divisive topic. Most Garmin fans swear by the Memory-in-Pixel (MIP) displays. They aren't bright. They aren't "pretty" in the traditional sense. But the crazier the sunlight gets, the easier they are to read. Plus, they stay on 24/7 without murdering your battery. While your friend's watch died three hours ago, your Forerunner is still chugging along with 14 days of juice left.
The ecosystem is the real product
When you buy a Garmin, you aren't just buying hardware. You're buying Garmin Connect. Unlike some competitors that charge a monthly "Pro" subscription to see your own health trends (looking at you, Fitbit and Oura), Garmin just gives you the data.
- Training Readiness: This is a score that looks at your sleep, recovery time, and recent stress. It tells you if you should crush a workout or stay on the couch.
- Body Battery: It sounds gimmicky. It’s surprisingly accurate. It uses Heart Rate Variability (HRV) to show your energy levels throughout the day.
- Acute Load: This tracks your exercise intensity over the last week to make sure you aren't overtraining and heading for an injury.
It’s a lot of data. Maybe too much for some. If you just want to count your steps, a $500 Garmin is overkill. But if you’re training for a PR, that data becomes a roadmap. You start to see patterns. You realize that two beers on a Friday night absolutely trashes your recovery score for the entire weekend. The watch doesn't judge you, but the numbers don't lie.
Maps that actually work offline
Most watches "tether" to your phone for navigation. If your phone dies or loses service, your map is gone. High-end Garmin watches come with TopoActive maps pre-loaded. These are real, topographical maps stored locally on the device. You can see contour lines, trail names, and points of interest.
I’ve been in situations in the backcountry where my phone was a paperweight because of the cold. My watch still knew exactly where the trailhead was. That’s not just a feature; it’s a safety tool. Features like "Back to Start" or "TracBack" can literally save your life if you get disoriented in the fog or after dark.
The "which one do I get" problem
Garmin’s biggest flaw is their product lineup. It’s a mess. There are dozens of models, and the naming conventions are confusing.

The Forerunner series is for runners. It’s light, plastic, and focused on pace. The 255 or 265 is the "sweet spot" for most people. The Fenix series is for the "outdoorsy" crowd—hikers, skiers, people who might accidentally bang their watch against a rock. It’s built like a tank. Then you have the Venu, which is their attempt at a lifestyle watch. It has the pretty screen, but it sacrifices some of the hardcore recovery metrics.
Then there's the Instinct. It looks like a Casio G-Shock from the 90s. It’s monochrome. It’s ugly to some, beautiful to others. But it’s nearly indestructible and the solar versions can theoretically have "infinite" battery life if you spend enough time outside.
What most people get wrong about accuracy
No wrist-based heart rate monitor is perfect. Optical sensors use light to measure blood flow, and that's prone to error. If you’re doing CrossFit or heavy lifting, the "cadence lock" can make your watch think your heart rate is your step count. Garmin knows this. That’s why their watches play so nicely with external chest straps. If you want 100% accuracy, you buy a HRM-Pro strap. The watch just acts as the brain.
Making the data work for you
Buying a Garmin watch with GPS won't make you faster. It won't make you lose weight. It’s a tool, not a magic wand. The value comes from the long-term trends. After six months of wearing it, you'll know your baseline. You'll know when you're getting sick before you even feel the symptoms because your resting heart rate will spike by 5-10 beats per minute.
If you’re ready to stop guessing and start measuring, here is how to actually use the thing:

- Ignore the first two weeks: The watch needs time to learn your physiology. Your "Training Status" will be "No Status" for a while. Let it calibrate.
- Wear it to sleep: Garmin’s sleep tracking is the foundation for almost all of its other metrics. If you don't wear it at night, the "Body Battery" and "Training Readiness" scores are useless.
- Customise your data screens: Don't settle for the factory settings. If you’re a runner, you might want "Lap Pace," "Average Pace," and "Heart Rate Zone" all on one screen. You can change this in the app.
- Sync with Garmin Connect: Check the "Reports" section on the web version of Garmin Connect. The desktop site offers way more deep-dive info than the mobile app.
- Use the "Courses" feature: If you’re traveling to a new city, use the Garmin Connect heatmaps to find out where the locals run. Upload the route to your watch and let it give you turn-by-turn directions.
Stop looking at your watch as a phone accessory. Start looking at it as a piece of specialized equipment. It's built for the 5 AM track sessions, the rain-soaked trails, and the data-heavy training blocks. If that sounds like you, the investment pays for itself in the first hundred miles.
