Apple Watch SE (2nd Gen) Review: The Best Budget Fitness Smartwatch?

Quick Verdict

The Apple Watch SE (2nd gen) sits in an awkward but appealing middle ground — it has almost everything most people actually use on a smartwatch, minus the bells and whistles that drive up the price of the Series 9. After wearing the renewed GPS + Cellular model for three weeks across gym sessions, morning runs, and a few pool laps, I can tell you where it genuinely excels and where the compromises show. Score: 4.5/5 — especially compelling at renewed pricing.

What Is the Apple Watch SE (2nd Gen)?

The Apple Watch SE is Apple's entry point into its smartwatch ecosystem, positioned below the Series 9 and the Ultra. This second-generation model launched in 2022 and shares the same S8 SiP processor as the Series 8, which means it feels just as snappy navigating menus and launching apps. The 40mm Starlight aluminum case I'm reviewing here is the smaller of the two case sizes, and paired with the included Sport Band it wears light — I honestly forgot it was on during a two-hour meeting one afternoon.

The "renewed" designation means this unit was inspected, tested, and certified by Apple or an Apple-authorized refurbisher. Functionally it performs like a new watch. The outer shell may have light marks from previous use, but the battery health on my review unit sat at 97%, which is better than many brand-new units I've encountered.

Key Features

• S8 SiP processor — the same chip inside the Series 8, delivering smooth watchOS 10 performance
• GPS + Cellular — make calls, stream music, and use maps without your iPhone
• 50m water resistance — safe for pool swims, ocean dips, and post-workout showers
• Fall Detection and Crash Detection — automatically contacts emergency services if you can't
• Heart rate monitoring with irregular rhythm notifications
• Apple Fitness+ trial — 3 months free with the watch
• Family Setup — pair the watch with an iPhone for kids or elderly relatives who don't have their own iPhone
• Swimproof design with dedicated Open Water and Pool swim modes
• Sleep tracking built into watchOS 10

Hands-On Review

I took the SE on a 5K run along my usual riverside route on a windy Thursday morning. Without my phone in my pocket — a first for me — the cellular connection held a stable LTE signal and Spotify kept playing through my AirPods. The GPS lock took about 45 seconds on a cold start, which is faster than I expected. By mile two I was checking my pace and heart rate zones with a quick wrist flick, and the display responded instantly every time.

What surprised me was the workout summary afterward. The Activity app broke down my run into splits, estimated my cardio fitness level, and logged it all automatically to Apple Health. I didn't open a single app — it just worked. That seamless integration with the Apple ecosystem is the part nobody talks about enough. If you're already in the iPhone-Mac-iPad loop, the Apple Watch doesn't feel like an add-on. It feels like a missing piece clicking into place.

Around the house and office, the watch handled notifications without being overwhelming. I turned off most social app pings early on — a habit I recommend everyone try for at least a week. Calls through the cellular radio sounded clear on my end during a quick check-in with my partner while grocery shopping, which addressed my main hesitation about the 40mm speaker being too small. It isn't.

Sleep tracking was a pleasant addition I didn't expect to rely on. I've used dedicated fitness bands for sleep before, but waking up to see my deep vs. light sleep percentages on my wrist first thing felt more actionable than digging into an app. Battery held up fine through the night — dropped from 82% to 61% after seven hours of sleep tracking, which left plenty of room for a morning walk and afternoon gym session.

Who Should Buy It?

You're upgrading from an older Apple Watch or switching from a basic fitness band and want the full Apple ecosystem experience without the Series 9 price premium. The cellular feature genuinely changes how you exercise — no phone bouncing in your pocket during runs or bike rides. Active individuals who run, swim, or hit the gym regularly will get the most out of the workout app and health monitoring. Parents and caregivers will appreciate Family Setup, which lets you manage an SE for a child or elderly relative who doesn't yet have their own iPhone.

Skip this if you need advanced health metrics like blood oxygen saturation, ECG outside the standard rhythm check, or temperature sensing for cycle tracking — those features are Series 9 and Ultra exclusive. And if you don't own an iPhone XS or later, this watch simply won't work for you, regardless of how tempting the renewed price looks.

Alternatives Worth Considering

Apple Watch Series 9 (refurbished) — If you can stretch the budget, the Series 9 adds an always-on display, blood oxygen sensing, a faster S9 chip, and the Double Tap gesture. The price gap narrows considerably when buying renewed through Apple.

Samsung Galaxy Watch 6 — A strong alternative for Android users, though you lose Apple Health integration and the polished watchOS app ecosystem entirely.

Garmin Forerunner 265 — For serious runners and triathletes who prioritize training load metrics, VO2 max accuracy, and multi-band GPS over smart features, Garmin's platform is still the gold standard. But you'll sacrifice cellular calling and the seamless Apple notification experience.

FAQ

Final Verdict

The Apple Watch SE (2nd gen) renewed is the smart buy for anyone who wants Apple's proven fitness tracking, safety features, and ecosystem integration without paying Series 9 prices. The cellular connectivity alone justifies the GPS + Cellular variant if you exercise without your phone, which most serious fitness users do at least a few times a week. Yes, the display is only 60Hz, and yes, you're missing blood oxygen and temperature sensors — but those matter far less in daily use than Apple's software polish, the reliable heart rate sensor, and that seamless handoff between your watch, phone, and Mac. At renewed pricing, this is the Apple Watch most people should actually buy.
