Can a Garmin golf watch connect to your home simulator? Yes. The Garmin Approach S70 and S62 sync with the R10 and R50 launch monitors through the Garmin Golf app, creating a unified data ecosystem. Every shot you hit in your garage uploads to the same profile that tracks your on-course rounds. The watch doesn’t connect to the monitor directly — it connects to the same Garmin account, so your practice data and your real-round data live in the same place. This means you can see whether that swing change you’ve been grinding on in the sim is actually showing up on the course.
Every Garmin Approach launch monitor owner eventually wonders about the watch. It’s sitting there in the Garmin Golf app, under “Devices,” asking if you’d like to add one. The R10 or R50 is the centerpiece of your sim setup, and Garmin keeps pushing you toward the full ecosystem.
The question is whether the S70 or S62 actually adds anything useful for someone who already has a launch monitor. Or is it just a GPS yardage display that happens to share a brand name?
The answer is more interesting than you’d expect.
The Watch Is Not the Sim Interface
Let’s clear up the most common misconception first. The Garmin Approach watch does not control your R10. It does not display your sim data during a practice session. It does not replace your phone or tablet as the R10’s display. If you’re looking for a wrist-mounted monitor for your garage sessions, this isn’t it.
The Garmin S70 and S62 are course-side tools. You wear them when you play actual golf. They give you distances to the front, middle, and back of the green. They track your shots automatically. They recommend clubs based on your swing history and the conditions. They display green contours and hazard layouts.
The connection to your sim setup is data-level, not operational. When you hit balls on the R10, the data goes to the Garmin Golf app. When you play a round with the S70 on your wrist, that data also goes to the Garmin Golf app. Both data streams live in the same account, under the same profile, in the same analytics dashboard.
The watch is the on-course data collector. The launch monitor is the practice data collector. The Garmin Golf app is the place where both talk to each other.
What the Data Loop Actually Does
Here’s what happens in practice. You spend January through March in the garage, hitting 200 balls a day on the R10. You’re working on a specific swing change — shallowing the club, shallowing the attack angle, whatever. The R10 captures every shot. The Garmin Golf app builds a trend line of your club path, face angle, and spin rate over weeks of practice.
April comes. You play your first real round. You wear the S70. The watch tracks every shot automatically — no tags, no sensors, no manual logging. It knows which club you hit and how far it went. It logs the dispersion, the accuracy, the green hit rate.
After the round, you open the Garmin Golf app. Both data sets are there. You can look at your practice swing path trend from March and compare it to your on-course dispersion from round one. You can see whether the mechanical change you made in the garage is producing different shot shapes on the course.
That’s the data loop. It’s not about the watch being a sim accessory. It’s about the watch being the verification tool — the thing that tells you whether your practice is actually working.
S70 vs S62: Which One Matters for Sim Owners
The S62 is the older model. It launched in 2020 and retails around $399. It has a 1.3-inch MIP display, 42,000 preloaded courses, automatic shot tracking, green contour maps, and a virtual caddie that factors in wind. GPS accuracy is within two yards of a laser rangefinder, which is effectively identical to the S70 in every condition I’ve tested.
The S70 is the current flagship. It launched in 2023 at $599. The big upgrade is the 1.4-inch AMOLED display — noticeably sharper, brighter in direct sunlight, and better looking as a daily watch. The virtual caddie adds elevation compensation on top of wind, which the S62 doesn’t have. It also has Wi-Fi for faster course updates, music storage, and more comprehensive health tracking (VO2 max, HRV, sleep stages).
For the sim owner specifically, the golf differences between the two are negligible. Both watches sync to the same Garmin Golf app. Both track shots automatically. Both feed data into the same practice-vs-course comparison. The S70’s AMOLED display is a genuinely better screen, and the virtual caddie with elevation is a nice upgrade. But neither changes the ecosystem experience.
The real question is whether you wear the watch as a daily device. If you already own a fitness tracker or a smartwatch and you only want golf-specific data, buy the S62 at $399. It does everything the S70 does for golf within 5%. If you’d wear the watch every day as your primary smartwatch, the S70’s screen and health features justify the $200 premium.
The Garmin Ecosystem Is the Moat
The reason to buy a Garmin watch over a Bushnell or a GolfBuddy or a random GPS watch is not the hardware. The hardware is fine — the S70 has a great screen, the S62 is a proven workhorse. But the hardware is not the point.
The point is that the R10 and the S70 share the same data pipeline. Every shot from your garage practice session and every shot from your Sunday round flow into the same analytics engine. The Garmin Golf app’s insights improve as both data sources accumulate. A month of garage practice plus a season of on-course rounds produces a performance profile that no single device can build on its own.
Bushnell has a version of this with the LINK ecosystem. FlightScope has it with the FSX platform. But Garmin is the only company that has a credible launch monitor AND a golf watch AND a unified app experience under the same brand. The R10 costs $599. The R50 costs $1,999. The S70 costs $599. The whole ecosystem — launch monitor, watch, app, course library — is under $3,000 for the full setup. That’s less than a single GC3.
The Real Reason to Buy
The S70 is a good golf watch. The S62 is a better value. The Garmin app ecosystem is genuinely useful. None of that is controversial.
Here’s the real argument for the watch: it makes your practice mean something. Without the on-course data, your R10 practice sessions are just numbers on a screen. You can see that your club path changed from 3 degrees out-to-in to 1 degree. But you don’t know whether that change produced better on-course results until you verify it with real round data. The watch is the verification tool.
If you hit 10,000 balls in the garage this winter and don’t have a way to measure whether it translated to the course, you wasted a lot of time. The S70 or S62 gives you that measurement. It’s not a sim accessory. It’s the piece that completes the feedback loop.
You can buy the S62 at $399 or the S70 at $599. Either one closes the loop. The question is whether you want to know if your practice is working.
