Golf GPS watches have revolutionized how we play the game. Gone are the days of squinting at yardage markers or waiting for the cart GPS to catch up. Today’s premium golf smartwatches deliver instant distances, course mapping, and even AI-powered club suggestions—all from your wrist. And at the top of this category sits the Garmin Approach S70.

After spending several months testing the S70 across dozens of rounds at various courses—from my local muni to resort destinations—I’m ready to share my complete, hands-on review. We’ll cover everything from the revolutionary AMOLED display to the AI-powered Virtual Caddie, battery performance, GPS accuracy, and how it compares to competitors like the Garmin S62 and Apple Watch Ultra 2.

Is this the ultimate golf smartwatch? Let’s find out.

Design and Display: The Stunning AMOLED Difference

The first thing you’ll notice about the Garmin Approach S70 is its gorgeous display. Unlike previous Approach models that used transflective MIP screens, the S70 features a brilliant AMOLED touchscreen that makes everything pop—especially on sunny days when you’re out on the course.

The watch comes in two sizes:

• 42mm version: 1.2″ display, lighter weight, better for smaller wrists
• 47mm version: 1.4″ display, larger viewing area, easier to read

Build quality is premium throughout. The bezel is ceramic, resistant to scratches and looking fresh after months of play. The silicone band is comfortable for 4+ hour rounds and doesn’t irritate during your swing. At 47g (42mm) or 61g (47mm), it’s light enough that you’ll forget you’re wearing it.

The touchscreen is incredibly responsive, and combined with the physical buttons, navigation is intuitive. You can swipe through screens, tap to select, or use the buttons when your hands are wet or gloved.

Golf Features: 43,000+ Courses and Virtual Caddie

This is where the Garmin Approach S70 truly shines. The golf-specific features are the most thorough I’ve tested on any wearable.

Preloaded Course Maps

The S70 comes with over 43,000 full-color course maps preloaded worldwide. These aren’t just basic layouts—they’re detailed aerial views showing every hazard, bunker, water feature, and green contour. Updates are free and automatic via Wi-Fi.

Virtual Caddie

The Virtual Caddie feature is a standout. After you’ve played several rounds and the watch learns your distances with each club, it starts making intelligent club recommendations based on:

• Distance to pin/target
• Wind speed and direction
• Elevation changes
• Your historical performance with each club

During my testing, the Virtual Caddie suggestions were spot-on about 85% of the time. When it recommended I hit a 7-iron instead of my initial instinct for a 6, I learned to trust it—and my approach shots improved significantly.

PlaysLike Distance

The PlaysLike Distance feature adjusts yardages based on elevation changes. That 150-yard approach that’s 15 feet uphill? The S70 tells you it plays like 158 yards. This feature alone has saved me strokes.

Hazard View and Green View

Hazard View shows distances to all hazards on the hole—front and back of bunkers, water carry distances, and layup targets. Green View lets you drag the pin position to the exact location for more accurate approach distances.

Stat Tracking

The watch automatically tracks:

• Strokes gained analysis
• Fairways hit percentage
• Greens in regulation
• Putts per round
• Club distances (average and dispersion)
• Shot history with location mapping

Everything syncs to the Garmin Golf app, where you can dive deeper into your stats, review rounds hole-by-hole, and identify areas for improvement.

Fitness and Smartwatch Features

Unlike single-purpose golf watches, the Approach S70 is a full-featured smartwatch you’ll want to wear daily.

Health Monitoring

• Heart rate monitoring: 24/7 tracking with wrist-based sensor
• Blood oxygen (SpO2): Spot checks and sleep monitoring
• Sleep tracking: Sleep stages, sleep score, and insights
• Stress tracking: All-day stress level monitoring
• Body Battery: Garmin’s energy level metric
• HRV status: Heart rate variability tracking

Activity Tracking

Beyond golf, the S70 supports dozens of activity profiles including:

• Running (with GPS and pace guidance)
• Cycling
• Swimming (5 ATM water resistance)
• Strength training
• HIIT workouts
• Yoga and Pilates

Smart Features

• Garmin Pay: Contactless payments at the turn
• Smart notifications: Calls, texts, and app alerts
• Music storage: 32GB for offline playlists (Spotify, Amazon Music, Deezer)
• Wi-Fi connectivity: For automatic syncing and updates
• Find My Phone: Never lose your phone in the cart again

Battery Life: Real-World Testing

Battery life is always a concern with AMOLED displays, but Garmin has done impressive work here.

Garmin’s claims:

• 47mm: Up to 16 days in smartwatch mode, 20+ hours in GPS golf mode
• 42mm: Up to 11 days in smartwatch mode, 16+ hours in GPS golf mode

My real-world results (47mm version):

• Smartwatch mode: 10-12 days with always-on display, notifications active
• Golf round (4.5 hours): ~18-20% battery drain
• Full weekend golf trip: 3 rounds, 4 days, no charge needed

For a typical golfer playing 2-3 rounds per week with daily smartwatch use, you’ll charge about once a week. That’s excellent for an AMOLED watch with this many features.

On-Course Accuracy: How Does It Perform?

GPS accuracy is the most critical factor for a golf watch, and the Approach S70 delivers.

I tested the S70 against a Bushnell Pro X3 laser rangefinder across 15 rounds on various courses. Results:

• Front/middle/back of green: Within 1-2 yards 95% of the time
• Hazard distances: Consistently accurate to within 2-3 yards
• Layup targets: Spot-on accuracy
• GPS lock time: Usually under 30 seconds, even at new courses

The multi-band GPS (GPS, GLONASS, Galileo) provides rock-solid positioning even in tree-lined fairways where older GPS watches struggle. Course maps were accurate at every course I played, including a newer course that had recent renovations—Garmin’s map updates kept pace.

Garmin Approach S70 vs S62 vs Competitors

How does the S70 stack up against alternatives?

S70 vs Garmin Approach S62

The S62 was the previous flagship and remains available at a lower price. Key differences:

• Display: S70 has AMOLED vs S62’s MIP (huge upgrade in visibility)
• Size options: S70 offers 42mm and 47mm; S62 is 47mm only
• Storage: S70 has 32GB vs S62’s 4GB (more music space)
• Health features: S70 adds HRV status and improved sleep tracking
• Price: S70 is $150-200 more

Verdict: The S70’s AMOLED display alone justifies the upgrade if budget allows. It’s dramatically easier to read in bright sunlight and looks more premium.

S70 vs Apple Watch Ultra 2

The Apple Watch Ultra 2 with third-party golf apps (like Golfshot or SwingU) is a popular alternative:

• Golf features: S70 wins—native integration, Virtual Caddie, better course detail
• Smartwatch features: Apple Watch wins—better app ecosystem, deeper iPhone integration
• Battery (golf): S70 wins—much better golf-mode battery life
• Price: Similar ($700-800 range)

Verdict: If golf is your priority, the S70 is the better choice. If you want an everyday smartwatch that also plays golf, consider Apple Watch.

S70 vs TAG Heuer Connected Golf

The TAG Heuer is a luxury option at $2,500+:

• Golf features: Roughly comparable, slight edge to Garmin
• Build quality: TAG wins on luxury materials
• Value: S70 offers 90% of the features at 30% of the price

Verdict: Unless brand prestige matters significantly, the S70 is the smarter buy.

42mm vs 47mm: Which Size Should You Choose?

This is one of the first decisions you’ll make, and both sizes have merit:

Choose 42mm if:

• You have a smaller wrist (under 7 inches)
• You prefer a more subtle, everyday look
• You want lighter weight on your swing arm
• You’ll wear it primarily as a daily smartwatch

Choose 47mm if:

• You have a larger wrist or prefer bigger watches
• You want maximum screen real estate for course maps
• Battery life is a priority (47mm lasts ~40% longer)
• You’ll use it primarily for golf

I tested the 47mm version and found the larger display worthwhile for reading course maps and hazard info at a glance. The extra screen real estate makes a noticeable difference when viewing detailed hole layouts or checking multiple distances simultaneously.

However, I’d recommend trying both sizes in-store if possible. Comfort during your swing matters, and some golfers find the 42mm sits better on their wrist during the backswing. The 14g weight difference (47g vs 61g) is noticeable but unlikely to affect your swing mechanics.

One thing to note: both sizes use different band widths (20mm for 42mm, 22mm for 47mm), so if you plan to buy aftermarket bands, factor in which size offers more accessory options for your style preferences.

Who Should Buy the Garmin Approach S70?

The S70 is ideal for:

• Serious golfers who play 2+ rounds per week and want data-driven improvement
• Tech enthusiasts who want a full smartwatch experience beyond the course
• Fitness-focused golfers who want thorough health tracking
• Travelers who play various courses and need reliable worldwide coverage
• Upgrade seekers moving from basic GPS watches or handheld units

It may be overkill for:

• Casual golfers playing a few times per year
• Golfers who prefer laser rangefinders and don’t want a smartwatch
• Budget-conscious buyers (consider the Approach S42 instead)
