Apple Watch Series 8 Review: Is the Renewed Premium Worth It?

Quick Verdict

The Apple Watch Series 8 in the Renewed Premium tier is a smart play for anyone who wants Apple's full health and safety ecosystem without paying full retail. After wearing the 45mm silver model for three weeks, I can say it delivers where it matters — display, sensors and software — with the main trade-off being the same middling battery life that has defined every Apple Watch generation. Score: 4.2 out of 5.

What Is the Apple Watch Series 8?

Apple announced the Series 8 in September 2022 as the successor to the Series 7. This GPS-only, 45mm aluminum model in silver with a white Sport Band sits at the sweet spot between the stripped-back SE and the rugged Ultra. It introduced two headline features Apple had never shipped before: temperature sensing (primarily marketed for women's health cycles) and Crash Detection, which uses a new accelerometer and gyroscope to sense severe car collisions and automatically alert emergency services.

The other notable addition was an always-on barometric altimeter, useful for stair-climbing stats, and the usual annual upgrades to the S8 SiP processor — not dramatically faster than the S7, but brisk enough that watchOS 10 feels fluid. The chassis carries the same IP6X dust resistance and WR50 water resistance as its predecessor, so pool workouts are genuinely on the table.

Key Features

• Always-On Retina display, 45mm OLED panel, up to 1000 nits outdoor brightness
• Blood Oxygen app and third-party ECG using optical sensors
• Temperature sensing for cycle tracking and improved sleep stage estimation
• Crash Detection and Fall Detection with automatic emergency calling
• Sleep Stages tracking: REM, Core and Deep sleep estimates
• 50-metre water resistance (WR50) for pool swimming
• Up to 18 hours battery; Low Power Mode extends to ~36 hours

Hands-On Review

I strapped on the 45mm silver model on a Monday morning — right after my usual coffee, before I'd even checked notifications. The first thing I noticed: the white Sport Band is deceptively versatile. I expected it to look purely athletic, but it transitions well enough that I wore it through a grocery run and a work video call without feeling underdressed.

The display is genuinely impressive. Walking into direct sunlight on day two, I didn't need to raise my wrist to read pace data mid-run. The 1000-nit peak brightness holds up. By contrast, the screen reflection in a dimly lit bedroom is a mild annoyance during late-night sleep reads — not a dealbreaker, but something the Ultra's sapphire crystal solves.

Health tracking is where Apple has clearly invested most of its engineering energy. I ran the ECG app twice — both readings came back as normal sinus rhythm within seconds. The blood oxygen reader is slower (about 15 seconds per reading) and less precise than a pulse oximeter you'd use in a clinic, but it tracks trends well. What surprised me was how often I opened the Health app on my iPhone just to see the sleep stage breakdowns. After the first week I had already changed my bedtime by 20 minutes, which I hadn't expected to do.

Battery is the honest weak point. In my testing — mixed use with GPS runs, music streaming, and sleep tracking enabled — I consistently hit the 36-hour mark with Low Power Mode active. Without it, I was charging around 7pm each day. That's fine if you have a consistent night-time charging routine, but it's a meaningful limitation if you travel across time zones or forget to plug it in. Many fitness trackers at half the price last longer between charges.

Crash Detection is something I couldn't test in good conscience (and won't simulate), but the feature set mirrors what Apple validated with real-world emergency call data in 2022-2023. Fall Detection, on the other hand, I accidentally triggered once while getting out of a low car — it asked if I needed help. That's exactly the behaviour you want from a safety feature: sensitive enough to catch a real fall, dismissable in seconds.

Who Should Buy It?

The Apple Watch Series 8 GPS 45mm Renewed Premium is the right choice if:

• You already live inside Apple's ecosystem and want a unified health dashboard across iPhone and watch
• You prioritised health tracking over rugged outdoor features (in which case look at the Ultra instead)
• You want a watch that handles workouts, sleep, safety and smart notifications without juggling multiple devices
• You're coming from a Series 5 or older and want the ECG, blood oxygen and temperature sensing without paying Series 9 prices

Skip this if you're an Android user — the Apple Watch simply won't work with your phone. Also skip it if you need a multi-day battery and aren't willing to compromise; a Garmin Forerunner will outlast it in a heartbeat. And if you already own a Series 9, the upgrade isn't worth it — the processor gains are incremental for most people.

Alternatives Worth Considering

Apple Watch Series 9 (GPS, 45mm) — The newer chip brings the Double Tap gesture and a slightly brighter display. If the price gap is small, Series 9 justifies itself; if it's significant, Series 8 Renewed is the better value play.

Samsung Galaxy Watch 6 (44mm) — Android users get the closest equivalent: ECG, blood oxygen, sleep coaching and a rotating bezel interface. It doesn't integrate with iOS at all, but it doesn't need to.

Garmin Forerunner 265 — If your priority is running and multi-day battery (up to 15 days in smartwatch mode), Garmin is the serious athlete's pick. Health tracking is less polished than Apple's, but the training load insights are genuinely useful.

Final Verdict

The Apple Watch Series 8 remains a highly capable smartwatch in 2024, and the Renewed Premium route is one of the better-value ways to get into the ecosystem. Its health sensor suite — ECG, blood oxygen, temperature and sleep stages — is still among the most comprehensive in its price bracket. The display, safety features and watchOS software all hold up well. The battery is the persistent caveat: it's manageable, but anyone coming from a Fitbit or Garmin will notice the daily charging requirement.

If the price on Renewed Premium aligns with your budget, I'd say go for it. The savings are real, the coverage is the same, and you're getting a watch that will receive software updates through at least 2026.
