It is 2026. You’ve probably seen the sleek, bezel-less curves of the Series 11 or the chunky, titanium frame of the Ultra 3 on people's wrists at the gym. But then, you spot it. A square-ish, slightly thicker silhouette with a distinct red dot on the crown. The Series 3. Honestly, seeing one in the wild today feels a bit like spotting a well-maintained 1990s Honda Civic. It’s not flashy, but it refuses to die.
I get asked a lot if the apple watch 3 features still hold water today. Some people think it’s a paperweight. Others swear by it for basic step tracking. The truth is somewhere in the messy middle. While Apple officially cut off software support years ago—the watch is permanently stuck on watchOS 8.8.1—there is a weirdly resilient subset of users who won't let go.
The Features That Defined an Era
When this thing dropped back in 2017, it was a massive deal. Like, "holy crap, I can leave my phone at home" kind of deal. This was the first time Apple successfully crammed a cellular radio into a watch. They used the actual screen as an antenna, which was pretty wild tech at the time. If you have the LTE version, you’ve got that iconic red cap on the Digital Crown. It’s basically a badge of honor now.
But let's look at what's actually under the hood.
The S3 chip was a beast in its day. It was 70% faster than the Series 2. That jump meant Siri could finally talk back to you through the speaker instead of just showing text like a shy robot. You also got a barometric altimeter. This was huge for hikers and people who take the stairs because it finally allowed the watch to track elevation gain. Before this, your watch basically guessed how many flights of stairs you climbed based on arm swings.
GPS was standard, too. You could go for a run, track your route, and the heart rate sensor—though not the fancy "medical grade" ones we have now—was surprisingly accurate for steady-state cardio.
What You’re Actually Getting (and What You’re Not)
If you are looking at the apple watch 3 features from a 2026 perspective, you need to be realistic. This isn't a modern smartwatch. It’s a fitness tracker with a screen.
- The Screen: It’s a Retina OLED, but it’s small. You have those chunky black borders (bezels) around the edges. It doesn't have the "Always-On" display that started with the Series 5. When you drop your arm, the screen goes black.
- Heart Health: You get high and low heart rate notifications. You do not get the ECG app or blood oxygen monitoring. If you’re worried about AFib, this isn’t the device for you.
- Water Resistance: It’s rated for 50 meters. You can swim with it. Just don't go scuba diving or high-speed water skiing. The seals on these old units can dry out over time, so if you've had one sitting in a drawer for five years, maybe don't jump into a pool immediately.
- Battery Life: Apple claimed 18 hours. In 2026, most Series 3 batteries are chemically aged. Expect maybe 10-12 hours if you're lucky, or much less if you use the GPS for a long workout.
Honestly, the biggest headache isn't the hardware. It's the storage. The GPS-only model has a measly 8GB of space. Back when it was getting updates, you often had to factory reset the entire watch just to install a software patch because there wasn't enough room. It was a nightmare. Now that updates have stopped, that's less of an issue, but don't expect to store a massive Spotify library on your wrist.
Why Do People Still Use It?
You’d think everyone would have upgraded by now. But the Series 3 has this "Goldilocks" vibe for a specific kind of person.

I know a guy, a marathon runner, who refuses to switch. Why? Because it’s light. The 38mm aluminum version weighs next to nothing. He doesn't care about "Double Tap" gestures or sleep apnea detection. He wants to see his pace, his distance, and his heart rate. The Series 3 does that perfectly.
Plus, there’s the cost. You can find these at garage sales or on eBay for the price of a decent lunch. For a kid's first watch or a "beater" watch for construction work, it makes a lot of sense. If you break it, you don't cry. You just move on.
The Compatibility Trap
Here is where things get tricky. If you’re thinking about buying one today, check your phone.
The Series 3 needs an iPhone running at least iOS 11. But here's the catch: if you buy a refurbished one that was updated to watchOS 8, you'll need a much newer iPhone to pair with it. It’s a weird software limbo. Most modern iPhones will still talk to it, but the setup process can be... finicky. You might spend an hour staring at a "Connecting" screen.
Also, many modern apps simply don't support watchOS 8 anymore. Big names like Starbucks or certain weather apps might not even show up in your watch’s App Store. You’re basically stuck with the built-in Apple apps: Mail, Messages, Workout, and Activity.
Making the Most of a Series 3 Today
If you have one or just picked one up, don't expect it to be a mini-iPhone. Treat it like a fancy Casio.
Turn off "Wake on Wrist Raise" if you want to save battery. Use a simple watch face with minimal complications. The "Modular" face is probably your best bet for utility. If you use it for workouts, try to keep them under an hour if you want the battery to last until dinner.
And for the love of all things tech, don't try to load it up with photos. That 8GB of storage is precious. Use it for the OS and maybe one small playlist of "emergency" running music.
Quick Actions for Series 3 Owners:
- Check Battery Health: Go to Settings > Battery > Battery Health. If it’s below 80%, the watch will likely throttle performance or die randomly during a workout.
- Optimize Complications: Stick to the basics like Weather and Activity. Heavy third-party complications will lag the interface.
- Clean the Sensor: Old sweat and grime can interfere with the heart rate LEDs. Use a damp, lint-free cloth. No soap!
The apple watch 3 features were groundbreaking once. Today, they are basic. But basic isn't always bad. If you just want to close your rings and get a buzz when your mom texts you, this old workhorse still gets the job done. Just don't expect it to keep up with the Series 11 in a sprint.
If your battery is truly shot, look into local electronics repair shops that specialize in battery swaps, as Apple's out-of-warranty service fee for this model often exceeds the actual value of the watch. Alternatively, consider using the device as a dedicated "sleep tracker" or a backup for when your primary watch is charging.
