Apple Watches deliver comprehensive health monitoring and seamless iPhone integration across designs ranging from everyday fitness tracking to extreme adventure capability. Choosing a refurbished smartwatch gives you access to Apple's wellness ecosystem while making an environmentally conscious decision. Find the Apple Watch that matches your lifestyle from casual wellness tracking to demanding outdoor pursuits.
What are the key features of Apple Watches?

- Safety features: fall detection, crash detection, and Emergency SOS with international calling

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 including ECG, temperature sensing, and blood oxygen monitoring can degrade from daily wear. Water resistance seals may be compromised, and battery health often suffers from charging cycles. 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, temperature, heart rate), GPS accuracy, display condition and brightness, Digital Crown and button operation, battery health, water resistance seal integrity, charging capability, and overall functionality. Every device comes with a minimum 1-year warranty and 30-day returns. You get Apple's advanced health tracking without premium pricing, while reducing electronic waste.

Which Apple Watch should you choose ?
Apple Watch Ultra is the premium adventure watch engineered for extreme conditions and serious outdoor athletes. The titanium case with sapphire crystal provides maximum durability against impacts and scratches. Battery life extends to 36 hours in normal use and 60 hours in Low Power Mode, far exceeding standard Apple Watch models. The 49mm display is the brightest Apple offers, readable even on glaciers and open water. The Action Button provides customizable quick access to workouts, compass waypoints, dive modes, or other functions. Dual-frequency GPS (L1 and L5) delivers superior accuracy in challenging environments. The Ultra is certified for recreational diving to 40 meters with the Oceanic+ app. The siren feature (86 decibels) helps attract attention in emergencies. Choose the refurbished Apple Watch Ultra if you're a mountaineer, trail runner, triathlete, diver, or adventure athlete needing maximum durability, extended battery, and specialized features for demanding pursuits. Choosing between generations? Our Apple Watch Ultra 3 vs Ultra 2 breakdown has you covered.
Apple Watch SE is the most accessible entry point into the Apple Watch lineup, covering the health and safety features most people actually need at a fraction of the Series price. On Back Market, you'll find both the SE 2 (2022) and the refurbished Apple Watch SE 3 (2025).
The SE 2 includes heart rate monitoring, crash detection, fall detection, Emergency SOS, and built-in GPS. It doesn't have an Always-On display, ECG, or blood oxygen monitoring.
The SE 3 adds an Always-On display, wrist temperature sensing, sleep score tracking, sleep apnea notifications, fast charging, and a crack-resistant display that's 4x tougher than earlier SE generations. It uses 100% recycled aluminum and comes in Midnight and Starlight. ECG and blood oxygen monitoring remain exclusive to the Series lineup across all SE models.
Pre-owned Apple Watch SE models on Back Market start from [STARTING PRICE: verify in CMS].
Choose the Apple Watch SE if you want Apple's essential health and safety features at the lowest price point on Back Market, you're buying for a younger user or as a gift, or ECG and blood oxygen monitoring aren't priorities for you.
Apple Watch Series 6, 7, 8 and 9: the mid-range sweet spot
These generations represent the most popular pre-owned Apple Watches at Back Market, offering flagship health features at accessible prices. Here's how they differ:
- Apple Watch Series 6 (2020): The first Apple Watch to combine ECG, blood oxygen monitoring, and an Always-On Retina display. A reliable, feature-complete choice at the lowest price in the premium tier.
- Apple Watch Series 7 (2021): A larger, crack-resistant display (41mm/45mm options), fast charging, ECG, blood oxygen monitoring, and always-on display. A meaningful upgrade in screen size and durability.
- Apple Watch Series 8 (2022): Adds crash detection and wrist temperature sensing for cycle tracking. Functionally close to the Series 7, but with significant safety and health upgrades.
- Apple Watch Series 9 (2023): The S9 chip brings on-device Siri processing, Double Tap gesture control, and a brighter 2,000-nit display. The strongest spec-to-price ratio before the Series 10.
All Series 6 through 9 models include ECG, blood oxygen monitoring, always-on display, built-in GPS, water resistance to 50 meters, and full Apple Pay and iPhone integration. Series 8 and 9 also include crash detection and fall detection.
Apple Watch Series 10 is Apple's thinnest Watch ever at 9.7mm, available in 42mm and 46mm cases, slightly wider than the Series 9's 41mm and 45mm. Released in September 2024, the Series 10 carries the full health suite: ECG, blood oxygen monitoring, wrist temperature sensing, crash detection, fall detection, and sleep apnea notifications via watchOS 11. The always-on Retina display reaches 2,000 nits of peak brightness. Fast charging brings the battery to 80% in around 30 minutes. The S9 chip delivers on-device Siri processing and Double Tap gesture control.
Choose the Apple Watch Series 10 if you want near-current Apple health technology at a pre-owned price well below a new model, or you prefer the larger, slimmer design over the Series 9. Curious about how it compares to Apple's newest model? We've done that comparison.
Apple Watch Series 11 is Apple's current flagship, released in September 2025. It's the first Apple Watch to offer possible hypertension notification, which can detect signs of chronic high blood pressure and alert you directly on your wrist. The Series 11 also introduces a Sleep Score feature for tracking and improving sleep quality, and Workout Buddy, which delivers personalized, audible real-time encouragement during exercise. The display is 2x more scratch resistant than Series 10, making it the toughest glass in any smartwatch. Battery life reaches up to 24 hours of typical use, and 5G cellular brings faster connectivity on the go. Available in aluminum and titanium, it includes the full health suite: ECG, blood oxygen monitoring, temperature sensing, crash detection, and fall detection.
Choose the Apple Watch Series 11 if you want Apple's most advanced health features (including hypertension notification), the most durable display in the Series lineup, and the longest software support ahead. Read the full Apple Watch Series 11 review to see whether the upgrade makes sense for you.
