I have wanted an Apple Watch for ages, so when I decided I was gonna buy one I instantly went to Back Market. I was thinking it wasn’t gonna be the best quality seeing as it’s only fair condition, but I guess I have been proved wrong, you can barely see any scratches (there aren’t many scratches anyway). And the packaging was incredible, I don’t think anything could have broken the watch with that packaging quality. Overall I am extremely impressed and happy with my purchase. Thank you again Back Market.😁

I had one issue with the device when I received it there was an Issue with the screen. I raised my concern to the company straight away and within minutes I had a returns label in my inbox. I sent it back and within a few days I received the same device back fixed so I have no issues with it whatsoever.

Having never had an Apple Watch before it took me a moment to orientate but once I got the hang of it, it was great. The one thing that bothered me was the strap was just the right length. I’m on the Last hole. But luckily, I will lose weight around my wrist rather than gain it. Full marks for another great product.

The watch arrived quickly, very well packaged, and looked practically brand new — I honestly couldn’t even tell it was refurbished. Setting it up was super easy and it works perfectly with all the features I wanted. The price was much better than buying new, and I really like that it’s also a more sustainable option. Overall, great value, excellent condition, and a smooth shopping experience. I’ll definitely be using Back Market again in the future!

Arrived on time as described on site. Condition barely shows previous wear. Set-up took little over an hour to confirm her phone compatible, but this had no bearing on the purchase of the watch or BackMarket. Daughter is over the moon with her first Apple Watch.

If I hadn’t known otherwise I would have sworn this was brand new, it came boxed with all the accessories including the film to keep the screen clean during transit. So I got the full unboxing experience! Watch is pristine and works perfectly. I couldn’t be happier. Good to know I’m getting a bargain as well as doing my bit to give older tech a second chance.

The Apple Watch Series 6 introduced blood oxygen monitoring to Apple's health-focused smartwatch lineup, expanding wellness insights beyond heart rate tracking. Choosing a refurbished Apple Watch Series 6 means accessing comprehensive health sensors and the always-on display whilst making a more sustainable choice. Find the smartwatch that delivers meaningful health data at an accessible price point.

What are the key features of the Apple Watch Series 6?

Brighter always-on display: 2.5 times brighter outdoors when wrist is down compared to Series 5

What are the differences between a refurbished and a used Apple Watch Series 6?

A used smartwatch is resold without professional inspection or guaranteed functionality. By contrast, a refurbished Apple Watch Series 6 from Back Market has been thoroughly tested by trusted refurbishers according to our Quality Charter. Each watch undergoes comprehensive checks covering the always-on display, blood oxygen sensor, ECG sensor, heart rate monitor, Digital Crown, buttons, GPS accuracy, and water resistance.

All our products come with a minimum 12-month warranty and a 30-day return period. You receive reliable technology that integrates smoothly into your daily routine whilst reducing electronic waste. Choosing refurbished means accessing Apple's health monitoring technology with confidence and peace of mind.

Who is the Apple Watch Series 6 best for?

The Apple Watch Series 6 suits users seeking comprehensive health monitoring at accessible refurbished pricing:

Health-conscious individuals: blood oxygen monitoring, ECG, and heart rate tracking provide valuable respiratory and cardiovascular insights
Altitude enthusiasts: SpO2 monitoring helps track acclimatization during hiking or travel to high-elevation destinations
Always-on display users: those wanting a constantly visible watch face with improved outdoor brightness
Fitness trackers: comprehensive workout modes and GPS tracking suit regular exercisers
Budget-conscious buyers: access to advanced health sensors at more affordable pricing when refurbished compared to newer models

Which Apple Watch should you choose?

Apple's smartwatch lineup has continued evolving since the Series 6's 2020 release. The Apple Watch Series 6 was the first model with blood oxygen monitoring, alongside introducing a brighter always-on display and faster S6 chip. It includes ECG, heart rate monitoring, compass, and Fall Detection. The Series 6 remains highly capable for users wanting these health sensors at an accessible refurbished price.

The Apple Watch SE (2nd generation) offers newer S8 chip technology and Crash Detection but removes the always-on display, ECG, and blood oxygen monitoring to achieve a lower price point. The Apple Watch Series 8 adds temperature sensing for cycle tracking and Crash Detection whilst maintaining all Series 6 health sensors. The Apple Watch Series 9 brings the significantly brighter 2000-nit display, even faster S9 chip, Double Tap gesture, and on-device Siri processing.

If blood oxygen monitoring and ECG are your priorities alongside the always-on display, the Series 6 offers excellent value when refurbished. Those wanting temperature tracking for cycle monitoring should consider the Series 8 or 9. Users who don't need advanced health sensors might find better value in the SE model. The Series 6 strikes a strong balance between comprehensive health features and affordability.

Buy a refurbished Apple Watch Series 6 at the best price on Back Market

Back Market offers the Apple Watch Series 6 refurbished at competitive prices without compromising on quality. Each watch is tested and verified by trusted refurbishers, complete with a minimum 12-month warranty. You'll benefit from excellent value on blood oxygen monitoring and ECG capability whilst supporting a more circular economy.

Our professional refurbishers conduct thorough quality checks, examining everything from the blood oxygen sensor to ECG accuracy and display brightness. Choose from different cosmetic grades (Pristine, Excellent, Good) depending on your budget and aesthetic preferences. With fast delivery, secure payment, and responsive customer service, buying refurbished Apple technology has never been more straightforward.

How does blood oxygen monitoring work on Apple Watch Series 6?

The Apple Watch Series 6 measures blood oxygen saturation (SpO2) using red and infrared LEDs on the back of the watch alongside photodiodes. These work together to measure the colour of your blood, which indicates oxygen levels. You can take on-demand readings through the Blood Oxygen app, which takes about 15 seconds with your arm resting on a flat surface. The watch also takes periodic background measurements during sleep and throughout the day. Normal blood oxygen levels typically range from 95-100%. Results are intended for general wellness purposes, not medical diagnosis. Factors like skin perfusion, tattoos, and how you wear the watch can affect accuracy. If you have concerns about respiratory health or consistently see low readings, consult a healthcare professional.

What's the difference between Apple Watch Series 6 and Series 7?

The Series 7, released in 2021, brought mostly design and display improvements rather than new health sensors. The Series 7 features a larger display with 20% more screen area due to smaller bezels and a redesigned front crystal, making text and complications easier to read. It offers faster charging (33% quicker than Series 6, reaching 80% in about 45 minutes) and increased durability with a thicker crystal and stronger geometry. The Series 7 includes IP6X dust resistance, absent from the Series 6. Both watches share identical health sensors: blood oxygen monitoring, ECG, heart rate tracking, and Fall Detection. The S7 chip in Series 7 offers similar performance to the S6. If larger display and faster charging matter to you, the Series 7 is worthwhile. For core health tracking functionality, the Series 6 offers essentially the same capabilities at better value when refurbished.

Can you track sleep with Apple Watch Series 6?

Yes, the Apple Watch Series 6 includes comprehensive sleep tracking capabilities through the Sleep app. The watch monitors your sleep duration, tracks sleep stages (REM, Core, and Deep sleep), measures respiratory rate, and can take blood oxygen readings during sleep. You can set sleep schedules and wind-down routines to establish consistent sleep habits. The watch provides sleep data in the Health app, showing trends over time. For optimal sleep tracking, you'll need to charge the watch at other times during the day, as wearing it overnight drains the battery. Many users charge their watch during their morning routine or evening relaxation time to ensure sufficient power for overnight tracking.

Does Apple Watch Series 6 have Crash Detection?

No, the Apple Watch Series 6 does not include Crash Detection. This feature was introduced with the Apple Watch Series 8, SE (2nd generation), and Ultra models in 2022. The Series 6 includes Fall Detection, which uses the accelerometer and gyroscope to detect hard falls and can automatically contact emergency services if you're unresponsive for 60 seconds. Fall Detection works well for detecting slips, trips, and falls during daily activities or exercise. If Crash Detection for severe car accidents is important to you, consider the Series 8, Series 9, or SE (2nd generation) models instead.

Are refurbished Apple Watch Series 6 devices covered by warranty?

Yes, all refurbished Apple Watch Series 6 devices on Back Market come with a minimum 12-month warranty. This warranty covers functional defects in essential components including the blood oxygen sensor, ECG sensor, heart rate monitor, always-on display, Digital Crown, side button, compass, GPS, and water resistance seals. You also benefit from a 30-day return period if the watch doesn't meet your expectations. Our customer service team is available to assist with any questions about your refurbished Apple Watch Series 6.
