What are the differences between a refurbished and a used Apple Watch?
A used Apple Watch is resold without professional inspection or warranty. Health sensors can degrade from daily wear, water resistance seals may be compromised from swimming and showering, and battery health can be significantly reduced. A refurbished Apple Watch from Back Market has been thoroughly tested by trusted refurbishers following our Quality Charter.
Each watch undergoes comprehensive inspection of all health sensors (ECG, blood oxygen, heart rate), GPS accuracy, display condition and brightness, battery health, water resistance seals, digital crown and button operation, and charging capability. Every device comes with a minimum 1-year warranty and 30-day returns. You get reliable health tracking and fitness features without the premium new price, while keeping quality electronics in circulation longer.

- Active families: cellular models let you stay connected during activities without carrying your iPhone
Which Apple Watch should you choose?
Apple Watch Series 8 is the most feature-complete option in this lineup with temperature sensing for cycle tracking and crash detection for vehicle accidents. It includes all the health sensors: blood oxygen monitoring, ECG, heart rate tracking, and sleep analysis. The 41mm and 45mm displays are 20% larger than Series 6 with crack-resistant crystal and IP6X dust resistance. Choose Series 8 if you want the most advanced health monitoring including temperature sensing or need crash detection for safety.
Apple Watch Series 7 offers nearly identical features to Series 8 minus temperature sensing and crash detection. It brought the larger display (20% bigger than Series 6) with crack-resistant front crystal, faster charging (33% quicker than Series 6), and IP6X dust resistance. It includes blood oxygen, ECG, Always-On Display, and comprehensive fitness tracking. Choose Series 7 if you want the larger screen and improved durability at better refurbished prices than Series 8, and temperature sensing doesn't matter to you.
Apple Watch Series 6 introduced blood oxygen monitoring and features an Always-On Display that's 2.5x brighter outdoors than Series 5. It includes ECG, fall detection, and always-on altimeter for continuous elevation tracking. The display is smaller than Series 7 and 8, and it charges slightly slower. Choose Series 6 if you want blood oxygen monitoring and ECG at the most affordable price point among Always-On Display models, and the smaller screen works fine for you.
Apple Watch SE 2 (2nd generation) is the budget-friendly option that launched alongside Series 8. It includes crash detection and fall detection but lacks Always-On Display, blood oxygen monitoring, ECG, and temperature sensing. It has the same S8 processor as Series 8 for smooth performance and the larger display size from Series 7/8. Choose SE 2 if you want recent features like crash detection and fast performance without paying for advanced health sensors you may not use.
Apple Watch SE (1st generation) is the original budget model from 2020. It provides essential fitness tracking, heart rate monitoring, fall detection, and GPS without Always-On Display or advanced health sensors. It uses the older S5 processor. Choose the original SE if you want the absolute lowest entry price into the Apple Watch ecosystem and only need basic fitness tracking and notifications.
Feature comparison summary: Series 8 has everything. Series 7 matches Series 8 minus temperature and crash detection. Series 6 adds blood oxygen to the essential features. SE 2 has essentials plus crash detection. SE 1 covers basics only.

What's the main difference between Apple Watch Series and SE models?
Series models (6, 7, 8) include advanced health sensors—ECG, blood oxygen monitoring, and Always-On Display—that SE models lack. Series watches also have more premium case materials available (stainless steel, titanium) beyond aluminum. SE models focus on essential fitness tracking: heart rate monitoring, GPS, fall detection, workout modes, and notifications without the advanced wellness sensors. SE models use slightly older processors but still handle daily tasks smoothly. If you want comprehensive health monitoring including ECG and blood oxygen, choose a Series model. If you primarily want fitness tracking, notifications, and Apple ecosystem integration without advanced sensors, SE models provide excellent value.
Do all Apple Watch models have Always-On Display?
No, only Series 5 and newer Series models (Series 6, 7, 8, 9) include Always-On Display. The Apple Watch SE and SE 2 do not have this feature—you need to raise your wrist, tap the screen, or press the digital crown to wake the display. Always-On Display keeps the time and complications visible at a dimmed brightness when your wrist is down, mimicking traditional watches. Many users find it convenient for checking the time at a glance. Others don't miss it and appreciate that SE models still provide all the health tracking and fitness features without this display technology.
Which Apple Watch has the best battery life?
All Apple Watch models in this lineup (Series 6, 7, 8, SE, SE 2) offer similar battery life—approximately 18 hours of typical use with standard settings. The Series 8 and SE 2 have slightly more efficient processors but don't translate to dramatically longer battery. During continuous GPS use for workouts, expect 6-8 hours across all models. Series 7 and 8 charge faster than Series 6 and SE models, which partially compensates for similar capacity. If you want significantly longer battery life (multiple days), you'd need to look at Garmin or other fitness-focused watches. All Apple Watches require charging roughly once daily with typical use.
Can I track sleep with all Apple Watch models?
Yes, all Apple Watch models from Series 6, 7, 8, SE, and SE 2 include sleep tracking that monitors sleep duration, sleep stages (REM, Core, Deep), heart rate, and respiratory rate. Sleep data syncs to the Health app. Series 8 adds temperature sensing during sleep for additional cycle tracking insights. All models need at least 30% battery to track sleep through the night, so you'll charge at another time during the day. The sleep tracking experience and accuracy are similar across all these models—the main difference is Series 8's temperature data for reproductive health tracking.
Do I need cellular connectivity on my Apple Watch?
Cellular connectivity (GPS + Cellular models) lets you make calls, send texts, stream music, and use apps without your iPhone nearby. You'll need a compatible wireless plan from your carrier, typically adding $5-15 monthly. GPS-only models require your iPhone within Bluetooth range for these features but can still track workouts with GPS independently. Choose Cellular if you want to leave your phone at home during runs, workouts, errands, or want emergency calling capability when separated from your phone. Choose GPS if you always carry your iPhone and want to avoid the extra monthly cost—you'll still get full fitness tracking and all features when your phone is nearby.
How long will these Apple Watch models receive software updates?
Apple typically supports Apple Watch models with watchOS updates for 4-6 years after release. Series 8 (2022) will likely receive updates through 2027-2028. Series 7 (2021) through 2026-2027. Series 6 (2020) through 2025-2026. SE 2 (2022) through 2027-2028. SE (2020) through 2025-2026. These are estimates—Apple doesn't officially announce end-of-support dates. Newer models (Series 8, SE 2) will receive updates longer. After support ends, the watch continues functioning but won't receive new features or security updates. If you want the longest software support, prioritize Series 8 or SE 2. For immediate use, all these models remain fully functional with current watchOS versions.
Can I use any Apple Watch with an Android phone?
No, all Apple Watches require an iPhone to set up and use. They only work within the Apple ecosystem and won't pair with Android devices. You need an iPhone 6s or later (specific iOS version varies by watch model). If you have an Android phone, consider Samsung Galaxy Watch, Google Pixel Watch, Garmin, or other Wear OS smartwatches designed for Android compatibility. Apple Watch integration is one of its strengths for iPhone users but means it's not an option for Android users.
What's the difference in display size between these models?
Series 7 and 8 have nearly 20% larger displays than Series 6 thanks to thinner borders—the 41mm and 45mm cases have more screen area. Series 6 comes in 40mm and 44mm with slightly smaller displays and thicker bezels. Both SE models match the Series 7/8 display sizes (40mm and 44mm options on SE, 40mm and 44mm on SE 2). The larger screens on Series 7, 8, and SE 2 make text easier to read and buttons easier to tap, especially during workouts. If you found older Apple Watches cramped, the Series 7/8/SE 2 screen expansion makes a noticeable difference. Series 6 is still perfectly usable but offers less screen real estate in similar case dimensions.
