Here’s the honest headline: these two Garmins give you the same distances from the same database — the only real difference is where you wear them. The Approach S12 is a wrist watch; the Approach G12 is a tiny clip-on. Both read front, center and back yardages to the green from Garmin’s 42,000+ preloaded courses, both carry that data with no subscription, both last up to a listed 30 hours in GPS mode, and neither reads to the flag the way a laser does. So this isn’t a contest about accuracy or features — it’s a question of format: do you want the number on your wrist, or clipped to your belt?
What both get right
Before the differences, it’s worth being clear how much these two share, because it’s nearly everything that matters. Both are built on the same sensible Garmin backbone: 42,000+ preloaded courses with free updates through the Garmin Golf app and, crucially, no subscription — you buy the device once and it keeps working, with none of the yearly-fee creep that shadows some distance apps. Both show you front, center and back numbers to the green plus basic hazard distances, which is most of what a recreational golfer actually uses. Both run a simple, low-power screen that drives one of the longest battery lives in the range — Garmin quotes up to 30 hours in GPS mode, several rounds between charges. And both share the fundamental GPS limit: they read to the mapped green, not the flag. In other words, the core experience is identical; the decision is entirely about the body it comes in.
Choose the Approach S12 if…
You’d rather glance at your wrist. A watch keeps the number always in your eyeline — you look down mid-stride and it’s there, no reaching for anything — which is why the wrist is the most popular way to get GPS distances. The S12 puts the front, center and back yardages on a clean monochrome display with button navigation, and for most players that always-there convenience is worth wearing a watch for. If you already wear a watch, or you like the number on your arm without a second thought, the S12 is the natural pick. Our full Garmin S12 review covers it on its own.
Choose the Approach G12 if…
You won’t wear a watch. Some golfers just don’t like a strap on the wrist, or find a watch face awkward to read mid-round — and for them the G12 is the answer: a tiny clip-on that attaches to a belt loop, pocket or bag and shows the same front, center and back numbers when you glance down. It’s one of the least fussy ways to get distances, with nothing to wear and nothing to hold. Pick the G12 specifically because you don’t want a watch — that’s its whole reason to exist — and see the full Garmin G12 review for the detail.
How they actually differ
The difference is the body, and two small things follow from it. The S12 is a wrist watch: the number is always in your eyeline, but you’re wearing a watch, and its monochrome screen with button navigation is a touch more of a “device” on your arm. The G12 is a clip-on: nothing on your wrist, but you do have to glance down at a belt or pocket rather than a raised arm, and its numbers-only screen is even more stripped-back. Neither has a color hole map or a touchscreen — both are deliberately simple, numbers-first devices — so the choice really does come down to wrist versus clip, not one being more capable than the other. Battery, database, accuracy and the no-subscription promise are the same on both.
Wrist vs clip-on, in daily use
Day to day, the split is smaller than it sounds, and both are easy to live with. The S12 on the wrist means the yardage is there the instant you look down, without reaching for anything — the fastest possible glance — at the cost of wearing a watch you might not otherwise want. The G12 clipped to a belt or bag means nothing on your wrist and nothing to hold, at the cost of a slightly deliberate glance down and a smaller, numbers-only readout. Walkers who like to travel light often prefer the clip; players who already wear a watch barely notice the S12. Both charge rarely thanks to that up-to-30-hour battery, both survive being knocked about, and both get out of the way once you’ve read the number — which is exactly what a budget GPS should do.
Skip the decision entirely if…
You want color hole maps, a touchscreen, or smartwatch features — because neither of these plain Garmins offers them, and the AMOLED Approach S44 is the upgrade that does (we weigh the two watches in Garmin S12 vs S44). Skip it, too, if the number you actually want is a pinpoint yardage to the flag: like every GPS, both the S12 and G12 read to the mapped green, not the pin, so for that you want a laser from the best rangefindersroundup. And if you want automatic shot tracking and free stats on top of the distances, a Shot Scope does that and these don’t. The whole subscription-free GPS field — watches and clip-ons alike — is ranked in our best GPS watches roundup.
The honest verdict
For most golfers the S12 is the easy default, simply because a wrist-glance is the most convenient way to get a distance — the number’s always there, and you never think about it. Choose the G12 instead when you specifically don’t want a watch: same distances, same battery, same no-subscription database, just clipped on rather than worn. There’s no wrong answer here and no value gap to agonise over — both are honest, subscription-free budget GPS devices that do the same job. Pick the format that matches how you’d rather carry it, and you’ve made the right call.
