What They Have in Common
Both are tier-3 budget watches under $200, no subscription required, with free course updates. Both show front/center/back distances, hazard yardages, green view, and digital scoring. Neither has heart rate, smartwatch notifications, music, or slope mode. Both weigh in around 34–35 grams (body-only). Tournament legal out of the box.
Where They Differ
Display: Readable vs. Pretty
The S12 uses a MIP display — monochrome, no color, not touchscreen, but genuinely excellent in bright sunlight. If you've ever tried to read a phone screen on a sunny day and failed, MIP is the opposite of that problem. You navigate with buttons, which takes about one round to learn and then becomes second nature.
The W11 flips this: 1.3-inch full-color TFT-LCD touchscreen at 240×240. It's bigger, it's color, and you tap to navigate. The tradeoff is that LCD displays can wash out in direct sun — that's not unique to GolfBuddy, it's just the physics of the display type. I don't have confirmation either way on how the W11 handles glare specifically, but if you play a lot of afternoon rounds in bright conditions, it's something to keep in mind before assuming color = better.
Battery: Night-and-Day Difference
This is the sharpest divide between these two watches. The S12 gets 30 hours in GPS mode. That's a round and a half without charging, or a full weekend trip without touching a cable. It's the longest GPS battery in Garmin's golf lineup and one of the best in the category.
The W11 spec table says 10 hours in GPS mode. (The marketing page says 13 — trust the spec table.) Ten hours covers a single round with some margin, but not much. If you're playing 36 in a day, you're probably charging between rounds. If you're forgetful about plugging in the night before, you'll feel it.
Green Contours: The W11's Real Advantage
Here's where the W11 earns its keep. Green undulation — actual slope visualization on the putting surface — is not a common feature at this price. Most watches at $150–$179 give you a basic green outline and a pin. The W11 shows you which way the green tilts, at least on courses where that data is available (the majority of US courses, per GolfBuddy). That's a feature you'd normally pay subscription fees to unlock on a Garmin or Shot Scope.
The S12 has green view — you can see the shape and move the pin — but no contour data. You're reading slopes the old-fashioned way.
Whether green contours actually help your putting depends entirely on how you use that information. Some golfers find it genuinely useful for pre-shot read confirmation. Others ignore it. Worth knowing it's there, though.
Shot Tracking: One-Sided
The S12 is compatible with Garmin's CT10 sensors — small clips that attach to your club grips and log every shot automatically. You have to buy them separately (around $170 for a full set), but the integration is there if you want it. Manual shot marking is also available directly from the watch.
The W11 has no shot tracking at all. No manual marking, no sensor compatibility, no stat capture. Scorecard only.
Who Should Buy Which
Get the Garmin Approach S12 if:
- You play 36 holes occasionally, or just don't want to think about charging
- You play in bright sun and want a display that doesn't make you squint
- You're already in the Garmin ecosystem and might add CT10 sensors later
- You prefer button navigation over touchscreen (many golfers do, especially with gloves on)
- Battery reliability matters more than green visualization
Get the GolfBuddy aim W11 if:
- You play one round at a time and charge after every session — 10 hours is fine for that
- Green contours are genuinely interesting to you and you don't want to pay a subscription to get them
- You prefer a color touchscreen and a bigger display face
- You're price-sensitive and can find it below the S12's $199 MSRP (worth checking — the W11's street price isn't listed by GolfBuddy directly)
One note on the W11: GolfBuddy has less brand presence than it used to, which affects things like warranty support and long-term app updates. Not a dealbreaker, but worth factoring in if you're the type to keep a watch for four or five years.
The Bottom Line
Two no-subscription budget watches, one meaningful tradeoff. The W11 gives you green undulation and a color touchscreen — things you'd expect to cost more. The S12 gives you a 30-hour GPS battery and Garmin's ecosystem reliability. For most golfers, the battery gap is the deciding factor. Forgetting to charge a watch with 30 hours left is forgivable. Forgetting to charge one with 10 is a problem.
