You remember the hype. September 2016. Tim Cook stands on stage, and suddenly the "smartwatch as a toy" era ends. The Apple Watch Series 2 was the moment Apple stopped guessing and started doing. It wasn't just a slight bump over the original; it was the birth of the fitness-first wearable we know today.
But honestly? Using one in 2026 is a wild experience.
It’s slow. Like, "go make a coffee while the weather app loads" slow. Yet, there is something remarkably sturdy about this little square of aluminum and sapphire.
What the Apple Watch Series 2 actually changed
Before this model, the Apple Watch was basically a notification buzzer that died if you looked at a swimming pool. The Series 2 changed the math. It introduced built-in GPS, which meant you could finally leave your heavy iPhone 7 at home and still track your run.
It was a big deal.
Then there was the "Swimproof" rating. Apple didn't just say it was water-resistant; they rated it for 50 meters. They even engineered that quirky speaker that vibrates to spit out water. You’ve probably heard that high-pitched beeping—it started right here.
The Specs That Time Forgot
- Processor: The S2 Dual-Core. It felt lightning-fast in 2016. Today, it struggles with basic system tasks.
- Display: 1,000 nits. This was a massive jump. It made the screen actually readable under the afternoon sun.
- Battery: 273mAh (for the 38mm) or 334mAh (for the 42mm).
Let's talk about that battery for a second. Apple claimed 18 hours. In reality, back in the day, you could sometimes squeeze two days out of it if you weren't using the GPS. Now? If you find a used Series 2, that lithium-ion cell is likely chemically aged into oblivion. Most units in 2026 struggle to stay alive for a four-hour walk.
Is it still "usable" today?
Depends on what you mean by "usable."
If you want to run the latest apps, forget it. The Apple Watch Series 2 is stuck on watchOS 6.3. Apple cut off software support years ago. It won't pair with a modern iPhone running iOS 19 or 20 without some serious Bluetooth gymnastics, and even then, half the features will be broken.
No ECG. No Blood Oxygen. No Always-On display.

However, if you just want a digital watch that tracks your steps and vibrates when your mom texts you, it technically still does that. The heart rate sensor—while not as sophisticated as the Series 11—is surprisingly accurate for basic cardio.
I’ve seen people using these as dedicated "beater" watches for the gym. Why scratch a $400 Series 10 when a $30 Series 2 can still count your reps and time your rests?
The Ceramic Edition: A forgotten masterpiece
We have to talk about the White Ceramic. It was the "Edition" model for the Series 2, replacing the ridiculously expensive $10,000 gold version from the first generation.
It was stunning.
Four times harder than stainless steel. It had this milky, pearlescent finish that never scratched. Even in 2026, a ceramic Series 2 looks like a piece of modern art. It’s a tragedy Apple doesn’t offer a ceramic finish in the standard lineup anymore, usually reserving those high-end materials for the Ultra or special anniversary drops.
The GPS battery drain problem
The biggest "gotcha" with the Series 2 was always the GPS.
While it was the headline feature, it was also a battery vampire. If you started a workout with the GPS active, you had about 5 hours of life. Total. For a marathon runner, that was cutting it way too close.
In 2026, with a degraded battery, that GPS probably lasts 45 minutes. Basically, it’s a wired watch that isn’t plugged in.
Why some people still hold onto them
Collectors. That's the main group now. Or people who inherited one and don't want to contribute to e-waste.
There's also a weird nostalgia for the "thick" Apple Watch. The Series 2 was actually slightly thicker (about 0.9mm) than the Series 1 to accommodate the bigger battery and the GPS chip. It felt tool-like. Substantial.

What most people get wrong
People think the Series 2 and the "Series 1" (released at the same time) were the same. They weren't. The Series 1 had the dual-core chip but lacked the GPS, the 1000-nit screen, and the 50m water resistance. If you’re buying one for $20 on eBay, make sure you’re actually getting the Series 2. Look for the "GPS" engraving on the back casing.
Actionable steps for Series 2 owners in 2026
If you still have one of these sitting in a drawer, here is what you should actually do with it:
- Check the Battery Health: If it’s below 80%, it will likely shut down randomly during a workout. Apple won't "repair" these anymore; they’ll just offer you a recycling credit.
- Use it as a dedicated Sleep Tracker: Since the battery life is shot, wear it only at night to track sleep cycles and use the silent vibrating alarm to wake up without waking your partner.
- Reset and Strip it: To make it feel "fast," delete every third-party app. Keep it strictly for system functions like Alarms, Timer, and Heart Rate.
- Repurpose the Band: The 38mm/40mm/41mm and 42mm/44mm/45mm/49mm band compatibility has remained remarkably consistent. Your old Series 2 bands will fit a brand new Apple Watch Series 11 or Ultra 3.
- Recycle responsibly: If the screen is popping off (a sign of a swollen battery), stop using it immediately. Take it to an Apple Store for free recycling.
The Apple Watch Series 2 was a pioneer. It taught Apple that we didn't want a gold jewelry piece; we wanted a fitness tool that could survive a lap in the pool. It’s a legacy worth respecting, even if its processor can’t keep up with the modern world.
