What are the differences between a refurbished and a used Apple Watch?
A used smartwatch is resold without professional inspection or guaranteed functionality. By contrast, a refurbished Apple Watch from Back Market has been thoroughly tested by trusted refurbishers according to our Quality Charter. Each watch undergoes comprehensive checks covering the display, Digital Crown, buttons, health sensors, 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 seamlessly into your daily routine whilst reducing electronic waste. Choosing refurbished means accessing Apple's health ecosystem with confidence and peace of mind.
Who are Apple Watches best for?
Apple Watches suit a broad spectrum of users within the iPhone ecosystem:
- iPhone users: seamless integration makes Apple Watch the natural choice for anyone in Apple's ecosystem
- Health-conscious individuals: comprehensive sensors including ECG, blood oxygen, and temperature tracking provide meaningful health insights
- Fitness enthusiasts: from casual exercisers to endurance athletes, Apple Watch offers tracking for all activity levels
- Safety-focused users: Fall Detection and Crash Detection provide reassurance for older adults, cyclists, and drivers
- Outdoor adventurers: Apple Watch Ultra models deliver rugged durability and advanced navigation for extreme conditions
Which Apple Watch should you choose?
Apple's smartwatch lineup spans from essential tracking to professional-grade capabilities. The Apple Watch SE (2nd generation) delivers core smartwatch functionality including heart rate monitoring, Fall Detection, Crash Detection, GPS, and comprehensive fitness tracking at the most accessible price point. It's ideal for first-time smartwatch users, budget-conscious buyers, or those who don't need advanced health sensors like ECG or blood oxygen monitoring. The SE provides excellent everyday value.
The Apple Watch Series 9 represents Apple's mainstream smartwatch with comprehensive health sensors including ECG, blood oxygen, and temperature sensing for cycle tracking. It features the bright 2000-nit display, fast S9 chip, Double Tap gesture control, and on-device Siri processing. Available in 41mm and 45mm sizes, it suits most users wanting complete health monitoring with the latest Apple innovations. The Series 9 offers the best balance between features and wearability for everyday use.
The Apple Watch Ultra 2 targets extreme sports enthusiasts and outdoor adventurers with its 49mm titanium case, brightest display in the lineup, dual-frequency GPS for exceptional accuracy, depth gauge for diving to 40m, emergency siren, and Action Button for quick access to features. The Ultra 2 includes all Series health sensors plus enhanced durability, extended GPS precision, and specialised features for challenging environments. It's noticeably larger and heavier, making it less suitable for discreet wear but ideal for demanding outdoor activities, endurance sports, and professional use.
Choose the SE for essential tracking at the best value, the Series 9 for comprehensive health monitoring with everyday comfort, or the Ultra 2 for extreme durability and specialised outdoor features. All require iPhones for setup and full functionality, with cellular models offering independence from your phone.

What health features do Apple Watches offer?
Apple Watches provide comprehensive health monitoring that varies by model. Series 4 and later (excluding SE) include ECG capability for detecting atrial fibrillation and irregular heart rhythms. Series 6 and later add blood oxygen (SpO2) monitoring for respiratory health insights. Series 8 and later feature temperature sensing for cycle tracking and retrospective ovulation estimates. All models include continuous heart rate monitoring with high, low, and irregular rhythm notifications. Sleep tracking monitors sleep stages (REM, Core, Deep) with respiratory rate. Fall Detection uses accelerometers to detect hard falls, whilst Crash Detection (Series 8, SE 2nd gen, and later) identifies severe car accidents. The Compass app provides heading and elevation data. All health data syncs to the Health app for long-term trend analysis.
Do Apple Watches work without an iPhone?
Apple Watches require an iPhone for initial setup and full functionality. However, once configured, GPS models can function independently for fitness tracking, music playback (if content is synced), timer and alarm functions, and accessing downloaded apps when your iPhone isn't nearby. GPS + Cellular models offer significantly more independence, allowing you to make calls, send messages, stream music, use Siri, and access apps over mobile networks without your iPhone present. You'll need a compatible mobile plan from your carrier to activate cellular features, which typically costs £5-10 monthly. For core health and fitness tracking during workouts, all models work well on their own once set up.
What's the difference between Apple Watch Ultra and Apple Watch Series 9?
The Ultra and Series 9 target different users despite sharing core health sensors. The Ultra features a 49mm titanium case compared to Series 9's aluminium 41mm or 45mm options—the Ultra is noticeably larger and heavier. The Ultra's display reaches 3000 nits brightness versus Series 9's 2000 nits, with a flat sapphire crystal for durability. The Ultra includes dual-frequency GPS (L1 + L5) for exceptional accuracy in challenging environments, whilst Series 9 uses standard GPS. The Ultra adds a depth gauge for diving to 40m, water resistance to 100m (vs 50m), an 86-decibel emergency siren, and a customisable Action Button. The Ultra's microphones and speakers are optimised for harsh conditions. Both include ECG, blood oxygen, temperature sensing, and Crash Detection. Choose the Ultra for extreme sports, outdoor adventures, and maximum durability. The Series 9 suits everyday wear with complete health tracking in a more refined, lighter package.
Can you swim with Apple Watches?
Yes, all current Apple Watch models are suitable for swimming. Apple Watch SE and all Series models are water-resistant to 50 metres (5ATM rating), designed for shallow-water activities like swimming in pools and open water. They include dedicated swimming workout modes that track laps, distance, and stroke types. The Apple Watch Ultra takes this further with 100m water resistance (10ATM), EN13319 certification for recreational scuba diving to 40m, a depth gauge, and water temperature sensor. After swimming, especially in chlorinated or salt water, rinse your watch with fresh water and dry it thoroughly. Use the water eject function (rotate the Digital Crown) to clear water from the speaker. Whilst suitable for swimming and showering, Apple Watches aren't designed for high-velocity water activities like jet skiing or deep diving beyond their rated depths.
Are refurbished Apple Watches covered by warranty?
Yes, all refurbished Apple Watches on Back Market come with a minimum 12-month warranty. This warranty covers functional defects in essential components including the display, Digital Crown, buttons, health sensors (ECG, heart rate, blood oxygen, temperature where applicable), GPS, accelerometer, 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.
