Garmin Approach S70 vs Apple Watch Ultra for Golf: Which One Actually Wins on the Course?

Here’s a question that comes up a lot at the first tee: should I buy a dedicated golf GPS watch, or just load a golf app on my Apple Watch Ultra? It’s a fair question — the Apple Watch Ultra is a genuinely impressive piece of hardware, and the Garmin Approach S70 costs almost the same amount of money. So why would you pick one over the other?

The short answer: it depends entirely on what you want from a device on your wrist. But the long answer is way more interesting, and it’s going to save you from making a $700+ mistake. We’ve put both watches through real rounds to give you the honest breakdown — no marketing fluff, just what actually matters when you’re standing 178 yards out with a crosswind and a forced carry over water.

The Core Question: Dedicated Golf Watch vs. Smartwatch with Golf Apps

Before we get into specs, it’s worth framing what these two devices actually are, because they’re built with completely different philosophies.

The Garmin Approach S70 is purpose-built for golf. Garmin has been making GPS golf devices for over 15 years, and the S70 represents the apex of that experience. Every feature, every menu, every data point was designed with golfers in mind. You strap it on, walk to the course, and it just works — course maps load automatically, hazard distances appear without any button mashing, and the battery laughs at 18 holes.

The Apple Watch Ultra, on the other hand, is a premium general-purpose smartwatch that happens to support golf apps. It’s an extraordinary piece of technology built for athletes, adventurers, and Apple ecosystem users — but “golfer” isn’t the persona Apple had in mind when they designed it. You can absolutely play golf with it using apps like Golfshot, Arccos, or SwingU. But you’re layering golf functionality on top of a device that was built for everything else first.

That distinction drives almost every difference we’re about to discuss. Neither approach is wrong — but one is going to fit your life better than the other.

Garmin Approach S70: What You’re Actually Getting

The S70 comes in two sizes — 42mm and 47mm — both featuring a stunning AMOLED color touchscreen display. The 47mm is the one most golfers opt for since more screen real estate means more data at a glance, though the 42mm is a solid choice if you prefer a smaller profile on your wrist or a lower price point.

Course Coverage and Maps

This is where the S70 simply runs away from the competition. It comes preloaded with maps for 43,000+ golf courses worldwide — that’s essentially every course you’ll ever play, plus ones in countries you’ll probably never visit. The maps aren’t just basic pin positions either. You get full-color, detailed overhead views of each hole with:

• Green Contour maps — slope and break data to help you read putts
• Hazard distances — front and back of every bunker, water hazard, and forced carry
• PlaysLike distance — adjusted yardages that account for elevation change, so that 165-yard uphill shot shows as the 175 it actually plays
• Dogleg distances — layup yardages to corners on blind or bending holes

You can scroll around the hole map, zoom in on the green, and check multiple hazard distances — all with glove-friendly swipes or button presses. The interface is genuinely fast. There’s no waiting, no loading spinners, no “refreshing data” messages mid-round.

Shot Tracking and Scoring

The S70 has Automatic Shot Detection — it uses the accelerometer to detect when you’ve made a swing and auto-logs your position. When you get to your ball, it calculates how far you hit it. At the end of the round, you have a complete shot-by-shot map of your entire game. This is huge for identifying patterns: which club is consistently leaving you in trouble, where on the course you’re hemorrhaging strokes, what your actual carry distances are (not what you think they are).

The Virtual Caddie feature takes all this data and makes club recommendations based on your shot history, current wind, and hole layout. It’s not magic — it’s statistics applied sensibly — but over time it becomes genuinely useful, especially for golfers still dialing in their distances.

Scoring is handled right on the watch. You can log your score hole by hole, track putts, mark fairways hit, and review your stats post-round. Sync to the Garmin Golf app and you’ve got a full history of every round you’ve ever played.

Battery Life

The S70 delivers 20+ hours in GPS golf mode. That’s not a typo — you can play back-to-back 18-hole rounds and still have battery to spare. For a casual golfer playing once or twice a week, you might charge it once every couple of weeks. In smartwatch mode (without active GPS), battery life stretches to multiple days.

This isn’t a minor point. Battery anxiety during a round is real, and the S70 completely eliminates it.

The 42mm vs. 47mm S70 Decision

If you’re deciding between the two S70 sizes, here’s the practical breakdown:

• 47mm — Bigger display, easier to read at a glance, more data on screen simultaneously. This is the one most golfers want. It’s the ASIN referenced in this article (B0C5YSFSLR).
• 42mm — Lighter on the wrist, slightly lower price, better for smaller wrists. Same core golf features, just in a more compact package.

If you’re on the fence, go 47mm. The larger screen genuinely matters when you’re reading a green contour map or glancing at hazard distances without pulling your reading glasses out.

Health and Fitness Beyond Golf

The S70 isn’t a one-trick pony. It tracks sleep, heart rate, Body Battery energy levels, stress, and supports activities like running, cycling, and swimming (it’s water-rated). It’s a solid daily wear watch. But let’s be honest — you’re not buying the S70 for its smartwatch features. You’re buying it for golf.

Apple Watch Ultra: The Other Side of the Argument

The Apple Watch Ultra (currently in its second generation) is a remarkable piece of hardware. It’s built for extreme sports and adventure — a titanium case, a flat sapphire crystal display, dual-frequency GPS (L1 + L5), up to 60 hours of battery in low-power mode, and a design that can handle serious punishment. It’s also deeply integrated into the Apple ecosystem in ways that no Android device or dedicated GPS watch can match.

Golf on Apple Watch Ultra: The App Reality

Here’s the deal: the Apple Watch Ultra has no native golf mode. To golf with it, you need a third-party app. The main options are:

• Golfshot — The most popular golf app for Apple Watch. GPS yardages, shot tracking, scoring, handicap tracking. Requires a subscription (~$30/year for GPS features).
• Arccos Caddie — The best shot-tracking system available, period. Requires Arccos sensors in your grips (~$229 for a set) plus a subscription. The Apple Watch app is a companion display.
• SwingU — Freemium option with solid GPS yardages and basic features at no cost, premium features behind a paywall.

These apps work. Golfshot’s GPS is accurate, and Arccos Caddie is genuinely the most sophisticated club tracking system on the market — arguably better than anything Garmin does natively. But there are real-world trade-offs:

• App launch time eats into your pre-round routine
• Golf apps drain battery significantly faster than Garmin’s optimized golf mode
• Course map quality varies by app — none are as polished as Garmin’s native experience
• Green Contour data and PlaysLike distances aren’t available in most golf apps
• You’re adding subscription costs on top of an already-expensive watch

Battery Life on the Course

This is the Apple Watch Ultra’s biggest weakness for golf. In normal GPS mode, the Ultra gets around 36 hours — impressive for a smartwatch. But GPS-intensive golf apps push that number down considerably. Running Golfshot with active GPS tracking for 18 holes can pull 3-5 hours of battery life depending on your pace and settings. If you’re playing 36 holes over a golf trip weekend, you’re charging between rounds.

Apple introduced a Low Power Mode that extends battery significantly, but you can’t use it while running a GPS-heavy golf app. It’s a real limitation.

Where Apple Watch Ultra Actually Wins

The Ultra is a better device for everything that isn’t golf-specific. Full stop.

• Notifications — Texts, calls, emails, Slack messages. All on your wrist, natively, without any weirdness.
• Apple Pay — Pay for your post-round drinks at the clubhouse bar without touching your wallet.
• Fitness tracking — Apple’s Activity rings, advanced workout metrics, VO2 max, ECG, blood oxygen. Best-in-class health features.
• Cellular connectivity — Leave your phone in the cart and stay connected. Call for a ride, check your tee time, whatever.
• Third-party app ecosystem — Thousands of apps. Spotify, navigation, calendar, everything.
• Apple ecosystem integration — If you’re deep in Apple (iPhone, AirPods, MacBook, iPad), the Watch Ultra ties everything together in ways Android or Garmin simply can’t replicate.

If you’re a golfer who also runs, cycles, hikes, travels, and spends your non-golf life as an Apple power user, the Ultra makes a compelling case as a single device for all of it.

For golf app purchases and the Apple Watch Ultra hardware, we recommend buying directly from Apple.com or Best Buy — both offer reliable stock, easy returns, and AppleCare+ options that are worth considering at this price point.

Head-to-Head Comparison

GPS Accuracy: Is There Actually a Difference?

Both watches are accurate enough for golf. The Apple Watch Ultra’s dual-frequency GPS (L1 + L5) is technically more advanced hardware — it’s designed for precision in challenging environments like dense urban canyons or tree cover. On a golf course, that precision advantage mostly disappears. Both devices will give you yardages that are accurate to within a yard or two of the actual distance, which is well within the margin of what matters on the course.

Where the Garmin has a consistent edge isn’t raw GPS accuracy — it’s data quality. Garmin’s team has physically mapped and verified tens of thousands of courses. The hazard positions, green shapes, and pin locations in Garmin’s database are more comprehensive and consistently updated than what most golf apps pull. That matters less for front/center/back yardages and more for precise hazard carry distances and accurate green contours.

For an objective look at how GPS accuracy compares across dedicated golf devices, the MyGolfSpy GPS watch testing methodology is one of the more rigorous independent analyses available.

Ease of Use on the Course

This is where the experience gap is most pronounced. The Garmin Approach S70 is designed so that every piece of information you need is accessible within one or two button presses. You never have to navigate menus during a round — the watch surfaces the right data at the right time automatically. Distance to the pin: right there. Hazard distances: swipe. Green contour: tap. It’s frictionless in a way that matters when you’re trying to stay in your routine and not overthink your shot.

The Apple Watch Ultra with a golf app requires a bit more active management. You’ll be tapping the screen, navigating to the right screen in the app, and sometimes waiting for data to refresh. It’s not difficult, but it adds a small layer of cognitive load that compounds across 18 holes. On a busy Saturday with a group behind you, that friction feels more significant.

There’s also the notification problem. With the Apple Watch Ultra, you’re wearing a fully connected smartwatch. When your buddy texts you during your backswing window or a work email pops up between shots, the Watch is going to let you know. This is either a feature or a bug depending on your personality. Some golfers want to be fully disconnected during a round. Others genuinely need to stay reachable. Know which one you are before you decide.

Price: What Are You Actually Paying?

Let’s be direct about the total cost of ownership:

Garmin Approach S70 (47mm): ~$699. The Garmin Golf app is free for basic features. Premium Garmin Golf (more stats, competition features) runs ~$9.99/month or ~$99/year — optional, not required for core functionality.

Apple Watch Ultra: ~$799 for the watch alone. Add a Golfshot GPS subscription (~$30/year) or SwingU premium (~$40/year) and you’re at $830–$840+ before AppleCare or a new band. If you want Arccos Caddie (genuinely the best shot-tracking available), add another ~$229 for sensors plus a subscription. The Apple Watch Ultra’s golf setup can easily eclipse $1,000 once you account for the apps that make it actually useful on the course.

The S70 wins on pure golf value. The Ultra’s higher total cost is justified only if you’re using it for substantially more than golf.

Who Should Buy the Garmin Approach S70

The S70 is the right call if:

• You play golf regularly — at least a few times a month — and want the absolute best golf-specific experience on your wrist
• You care about Green Contour maps, PlaysLike distances, and comprehensive hazard data
• Battery life anxiety during a round is something you want to eliminate completely
• You want automatic shot tracking without needing grip sensors or a subscription
• You don’t have strong feelings about being deeply integrated into the Apple ecosystem
• You want a daily wear watch that handles basic notifications and fitness without needing to be your primary smartwatch

If golf is the primary reason you’re buying a GPS watch, the Garmin Approach S70 is the better golf watch. It’s not even a close call on pure golf features.

Who Should Buy the Apple Watch Ultra

The Apple Watch Ultra makes more sense if:

• You’re deep in the Apple ecosystem and already use an iPhone, AirPods, and other Apple devices
• Golf is one of several activities you want covered — you also run, hike, cycle, or swim seriously
• You want one device for everything: smartwatch, fitness tracker, golf GPS, cellular connection
• You already use Arccos Caddie (the Ultra is a great companion display for that system)
• Staying connected — calls, messages, notifications — during your round is important to you
• You care about the daily smartwatch experience as much or more than golf-specific features

The Apple Watch Ultra is a great watch for a golfer. It’s just not a great golf watch first. That’s an important distinction.

The Pairing Play: Can You Use Both?

Here’s a take worth considering: some serious golfers use a dedicated Garmin on the course and an Apple Watch (or other smartwatch) as their daily wear. The Garmin handles the golf experience perfectly, and the Apple Watch handles everything else. If you’re already invested in the Apple ecosystem and want the best golf experience money can buy, this two-watch strategy isn’t as crazy as it sounds — especially since you could use the S70 42mm (lower price point) and a standard Apple Watch Series 10 instead of the Ultra.

That said, most people want one device. Which is exactly why this comparison exists.

Final Verdict

For Garmin Approach S70 vs Apple Watch Ultra golf, the winner depends on who you are as a golfer — and as a person.

If your wrist real estate is going to a device that lives on the golf course and happens to also work great as a daily wear fitness tracker, the Garmin Approach S70 is the right choice. The course coverage, green contour maps, battery life, PlaysLike distances, and seamless in-round experience are genuinely in a different league than what you can replicate with an Apple Watch and a golf app. At $699, you’re getting purpose-built excellence for the game.

If you’re a passionate golfer but also an Apple power user who wants one device to rule them all — calls, messages, fitness, golf — the Apple Watch Ultra is a legitimate option. Pair it with a strong golf app like Golfshot or invest in the Arccos ecosystem, and you’ll have a capable on-course companion. Just go in with realistic expectations about battery life and the golf experience ceiling.

Either way, you’re putting serious technology on your wrist. Make sure it’s working for how you play.
