What are the differences between a refurbished and a used Apple Watch Series 3?
A used Apple Watch Series 3 is resold without professional inspection or warranty. Given the Series 3's age (released in 2017), used units may have degraded batteries, worn water resistance seals, or scratched displays from years of use. A refurbished Apple Watch Series 3 from Back Market has been thoroughly tested by trusted refurbishers following our Quality Charter.
Each watch undergoes comprehensive inspection of heart rate sensor accuracy, GPS functionality, battery health, water resistance seals, digital crown operation, touchscreen responsiveness, and charging capability. Every device comes with a minimum 1-year warranty and 30-day returns. You get reliable basic health tracking and Apple Watch features at the most accessible refurbished price, while extending the life of functional electronics.
Who is the Apple Watch Series 3 best for?
The Apple Watch Series 3 serves specific types of users well:
- Budget-conscious iPhone users: entry point into the Apple Watch ecosystem without paying for features you may not need
- First-time smartwatch buyers: learn whether you'll actually use a smartwatch before investing in more expensive models
- Casual fitness trackers: basic workout tracking, heart rate monitoring, and activity rings cover everyday fitness needs
- People wanting simple notifications: receive texts, calls, and app alerts on your wrist without overwhelming complexity
- Swimmers needing basic tracking: pool and open water swim modes track distance and duration reliably
- Users with older iPhones: if your phone can't support the latest Apple Watch models, the Series 3 remains compatible
- Parents buying for kids or teens: provides safety features like emergency calling without the expense of newer models
Apple Watch Series 3 vs newer models: what are you missing?
The Apple Watch Series 3 lacks several features found on newer models. There's no Always-On Display—you need to raise your wrist or tap the screen to see the time. It doesn't include blood oxygen monitoring, ECG capability, temperature sensing, or fall detection. The screen is smaller with thicker bezels compared to Series 4 and later models that expanded display size in the same case dimensions.
Storage is limited to 8GB (GPS model) or 16GB (Cellular), which can fill up quickly with watchOS updates, limiting app installation space. The S3 processor is noticeably slower than newer chips when opening apps or processing Siri requests. Crash detection, double tap gestures, and other recent innovations aren't available.
However, the Series 3 still handles core Apple Watch functions well: fitness tracking with GPS, heart rate monitoring, swim tracking, Apple Pay, notifications, music control, and third-party apps (though limited by storage). Battery life remains solid at roughly 18 hours of typical use.
Choose the Series 3 if you want basic Apple Watch functionality at the lowest price and don't need advanced health sensors or the latest features. Consider newer models (SE, Series 8, Series 9) if you want Always-On Display, larger screen, ECG, blood oxygen monitoring, or faster performance—these features significantly improve the daily experience.

Is the Apple Watch Series 3 still supported by Apple?
As of 2026, the Apple Watch Series 3 (released in 2017) is approaching the end of official software support. Apple typically supports devices for about 5-7 years with watchOS updates. The Series 3 may not receive the latest watchOS versions, which means you'll miss new features and eventually security updates. However, the watch continues to function with its current software for basic fitness tracking, notifications, and core Apple Watch features. If you want guaranteed long-term software support, consider newer models like the SE, Series 8, or Series 9. The Series 3 works well for current needs but has limited future update potential.
Does the Apple Watch Series 3 have fall detection?
No, the Series 3 doesn't include fall detection. This safety feature was introduced with the Apple Watch Series 4 in 2018. Fall detection uses advanced motion sensors to identify hard falls and automatically call emergency services if you're unresponsive. If fall detection matters for safety—for older users, people with medical conditions, or athletes doing activities with fall risk—consider the Series 4 or newer models that include this feature.
Can I take an ECG with the Apple Watch Series 3?
No, the Series 3 doesn't include ECG capability. The electrocardiogram feature was introduced with the Apple Watch Series 4. The Series 3 monitors heart rate continuously and can send high/low heart rate notifications, but it can't perform ECG readings to check for atrial fibrillation or irregular heart rhythms. If ECG functionality matters for heart health monitoring, you'll need a Series 4 or newer model.
What's the battery life on the Apple Watch Series 3?
Expect up to 18 hours of typical use including notifications, occasional workout tracking, and heart rate monitoring. This matches Apple's battery estimate for most Apple Watch models through Series 8. During continuous GPS tracking for running or cycling, expect roughly 4-5 hours before needing to recharge. Given the Series 3's age, refurbished units may have slightly reduced battery capacity compared to when new—batteries naturally degrade over time. Back Market refurbishers test battery health, but very old batteries may not hold as much charge as newer models. Most users still get through a full day with typical use.
Can I track swimming with the Apple Watch Series 3?
Yes, the Series 3 is water-resistant to 50 meters and includes swim tracking for both pool and open water swimming. Pool mode tracks laps, distance, and calories based on your set pool length. Open water mode uses GPS to track swimming distance in lakes or oceans. The watch can detect different stroke types and provides basic swim metrics. After swimming, dry the watch and clear water from the speaker by swiping up from the watch face and tapping the water droplet icon to eject trapped water.
Does the Apple Watch Series 3 have Always-On Display?
No, the Series 3 doesn't include Always-On Display. The screen turns off when you lower your wrist and requires raising your wrist, tapping the display, or pressing the digital crown to wake. Always-On Display was introduced with the Series 5 in 2019, allowing the watch face to remain visible at all times with dimmed brightness. If you want to see the time without raising your wrist, consider Series 5 or newer models. Many users adapt to the Series 3's wake-on-wrist-raise, but it's a noticeable difference if you're used to traditional watches.
Can I use Apple Pay with the Apple Watch Series 3?
Yes, the Series 3 fully supports Apple Pay for contactless payments. You can add credit, debit, and transit cards to the Wallet app and pay by double-clicking the side button and holding the watch near a payment terminal. This works independently of your iPhone, so you can make purchases even if you leave your phone at home. Apple Pay functionality is identical across all Apple Watch models—the Series 3 handles contactless payments just as well as newer watches.
What's the storage capacity on the Apple Watch Series 3?
The GPS model has 8GB of storage while the GPS + Cellular model has 16GB. After the operating system, you typically have 3-5GB (GPS) or 8-10GB (Cellular) available for apps, music, photos, and data. This is significantly less than newer models with 32GB. Storage limitations can be frustrating—watchOS updates consume space, leaving little room for music downloads or many third-party apps. If you plan to store music or download many apps, the limited storage may be restrictive. For basic fitness tracking, notifications, and a few essential apps, it's manageable.
