Apple Watch Series 6 Renewed Review: Is It Worth It in 2024?

Quick Verdict

The Apple Watch Series 6 renewed is a strong buy if you want flagship smartwatch features without flagship pricing. The 44mm GPS + Cellular model we tested delivered reliable fitness tracking, a genuinely useful blood oxygen sensor, and that crisp always-on display. It lost half a star in my book for the cellular battery drain and the sheer size of the case on narrower wrists. At its renewed price point, it earns a 4.2 out of 5 — especially for fitness-focused buyers who don't need the latest Series 9 silicon.

What Is the Apple Watch Series 6?

The Apple Watch Series 6 launched in 2020 as Apple's mid-range flagship, slotting between the budget SE and the premium Edition models. This renewed unit is the 44mm GPS + Cellular configuration in silver stainless steel, paired with the white Sport Band. Apple discontinued the Series 6 when the Series 7 arrived, so renewed units now represent the most affordable way to get a relatively recent Apple Watch with blood oxygen and ECG capabilities.

In plain terms: you're getting a 2020 flagship smartwatch with Apple's S6 SiP processor, an always-on OLED Retina display, and a full suite of health sensors — all at a discount. The catch is that you're buying something someone else has used, even if it's been inspected and certified functional. For some shoppers, that's a dealbreaker. For others, it's smart spending.

Key Features

• Blood Oxygen Monitoring: Built-in sensor measures blood oxygen saturation levels for wellness insights
• Always-On Retina Display: Brighter OLED panel visible in direct sunlight without raising your wrist
• ECG and Heart Monitoring: Electrical heart sensor supports FDA-cleared ECG app plus continuous heart-rate tracking
• Advanced Fitness Tracking: Tracks workouts, active calories, stand hours, and 100+ exercise types via Apple Fitness+
• Integrated GPS: Records distance, pace, and route maps for outdoor runs and cycling without an iPhone nearby
• GPS + Cellular: LTE connectivity for calls, messages, and streaming music away from your phone

Hands-On Review

I unboxed this on a Tuesday morning — the renewed packaging was clean, not Apple-sterile, but everything inside was accounted for: watch, band, charging cable, and documentation. The silver stainless steel case had one faint hairline scratch on the left edge that wasn't photographed in the listing, which I'll admit irritated me for about ten minutes before I strapped it on and forgot about it entirely.

The setup process took under fifteen minutes, including pairing with my iPhone 13 and letting watchOS download updates. By day two, the blood oxygen readings felt routine — I'd check it after my morning walk, sometimes in the evening if I felt sluggish. The numbers aren't medical-grade, but they're consistent enough to notice when something feels off. The ECG app ran without issue, and the irregular rhythm notification feature is genuinely reassuring if you're monitoring cardiovascular health.

What surprised me was the always-on display. I expected it to be a minor convenience. Instead, it fundamentally changed how I used the watch — glancing at the time in a meeting, checking my step count mid-stride, reading a timer while cooking. It sounds obvious, but the difference between tapping to wake and just looking is sharper than I anticipated.

Here's the thing though: cellular mode is a battery killer. I streamed music on a four-hour hike last Saturday, left LTE on for the whole outing, and watched the battery indicator crawl from 100% to 18% by the time I got back to my car. GPS-only days are fine — I routinely hit 36 hours between charges. But if you buy this for the cellular connectivity and plan to use it, bring a battery pack or a charger for day two.

Who Should Buy It?

Active users who want health data — Runners, cyclists, and gym-goers who want GPS tracking, heart-rate zones, and blood oxygen monitoring in one device will get real use from the Series 6's fitness suite.

iPhone owners who avoid high prices — If you're on iOS and want a premium smartwatch experience without paying Series 9 prices, the renewed Series 6 hits a sweet spot of features and cost.

Wellness-focused older adults — The ECG and heart monitoring features offer genuine peace of mind, and the fall-detection capability is a practical safety layer for active seniors.

Skip this if you have very small wrists and find 44mm watches too heavy, or if you need the fastest processor and newest health sensors — the Series 9 or Ultra 2 would serve you better, though at significantly higher cost.

Alternatives Worth Considering

Apple Watch SE (2nd gen, renewed) — Lacks blood oxygen and ECG but runs the same watchOS and costs $50–80 less renewed. Fine trade-off if you don't need those specific health features.

Apple Watch Series 7 renewed — A larger display (45mm vs 44mm, same body), slightly faster charging, and a more durable front crystal make it the better choice if you can find it within $30–50 of the Series 6 price.

Samsung Galaxy Watch 6 (refurbished) — Android users shouldn't buy an Apple Watch at all. Samsung's health ecosystem is robust, and the Galaxy Watch 6 offers comparable fitness tracking on Android hardware.

Final Verdict

The renewed Apple Watch Series 6 earns its recommendation for fitness-focused iPhone users who want a proven smartwatch at a reasonable price. The blood oxygen sensor, always-on display, and integrated GPS all perform as advertised on a renewed unit, and the silver stainless steel case still looks the part two years after launch. The cellular battery life and 44mm bulk are honest trade-offs worth considering before you buy. For around $100 less than new, it's a精明 purchase — provided you buy from a seller with a solid renewal grade and a reasonable return window.
