The Samsung Galaxy S23 Ultra remains a compelling high-end smartphone in 2025, offering a superb camera, powerful performance and the unique S Pen. The slightly older status often means more affordable prices, especially on platforms like Back Market.

Watch has been great, better than expected. I get so much out of it, it kind of feels to good to be true. I've tried many apps to control my lifestyle the watch has got everything I need. It's given me a good insight how I can make little changes to my lifestyle. You guys really make everything affordable for everyone. I only buy from Backmarket and let anyone know who looks at my technology. Including trade in off old technology.

The watch was delivered quickly. It looks clean and nice. But the battery ran out quickly. I charged it up 100% before I started using it, and the only thing I did was setting up the app. The battery went flat next day. I have to charge the watch everyday. Other than that, the watch is in good condition.

Item itself is in immaculate condition however I paid extra for the stated excellent condition which to me includes all original packaging. This came in a brown backmarket box. Great when it was meant to be a gift. I've found this to be hit or miss with backmarket as to whether you get the original packaging. Wish they'd just state if it's original box or not.

The Samsung Galaxy Watch 4 marks Samsung's transition to Wear OS, bringing comprehensive health tracking and Google ecosystem integration together. Choosing a refurbished Galaxy Watch means accessing advanced features like body composition analysis whilst making a more sustainable choice. Find the smartwatch that delivers serious health insights at an accessible price point.

What are the key features of the Galaxy Watch 4?

Super AMOLED display: vibrant always-on screen available in 40mm and 44mm sizes
Body composition analysis: measures body fat percentage, skeletal muscle, BMI, and more using bioelectrical impedance
ECG and blood pressure monitoring: heart health tracking with irregular rhythm notifications
Advanced sleep tracking: monitors sleep stages with snoring detection and blood oxygen during sleep
Continuous heart rate monitoring: 24/7 tracking with alerts for abnormal readings
Built-in GPS: accurate route tracking for outdoor activities
Water resistant to 50m: suitable for swimming with 5ATM and IP68 ratings
Wear OS powered by Samsung: access to Google Play Store apps alongside Samsung Health
Compatible with Android: works with Android 6.0 or later

What are the differences between a refurbished and a used Galaxy Watch 4?

A used smartwatch is resold without professional verification or guaranteed performance. By contrast, a refurbished Galaxy Watch 4 from Back Market has been thoroughly tested by trusted refurbishers according to our Quality Charter. Each watch undergoes comprehensive checks covering the display, rotating bezel (on Classic models), buttons, health sensors, GPS accuracy, charging functionality, and water resistance seals.

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

Who is the Galaxy Watch 4 best for?

The Galaxy Watch 4 suits users seeking comprehensive health tracking without premium pricing:

Android users: seamless integration with Android phones, especially Samsung Galaxy devices, provides the best experience
Fitness-focused individuals: body composition analysis offers insights typically found on dedicated scales, making it valuable for tracking training progress
Health-conscious users: ECG, blood pressure monitoring, and advanced sleep tracking appeal to those monitoring cardiovascular health
First-time smartwatch buyers: the Watch 4 offers strong features at an accessible price point, particularly when refurbished
Samsung ecosystem users: integration with Galaxy Buds, Samsung Pay, and SmartThings creates convenient daily workflows

Which Samsung Galaxy Watch should you choose?

Samsung's smartwatch lineup has evolved significantly since the Watch 4's introduction. The Galaxy Watch 4 was the first Samsung smartwatch to combine Wear OS with body composition analysis, ECG, and blood pressure monitoring. It offers comprehensive health tracking at an attractive price point, available in standard and Classic versions (the Classic includes a physical rotating bezel for navigation). The watch works well for users wanting serious health features without needing the latest refinements.

The Galaxy Watch 5 improves upon the Watch 4 with sapphire crystal glass for better scratch resistance, enhanced GPS accuracy, improved skin temperature sensing, and faster charging. It's worth considering if durability and temperature tracking matter to you. The Galaxy Watch 5 Pro adds titanium construction, advanced GPS navigation, and route tracking for outdoor enthusiasts. The Galaxy Watch 6 offers further refinements with larger displays and improved heart rate accuracy.

If you're budget-conscious and want comprehensive health tracking including body composition analysis, the Galaxy Watch 4 delivers excellent value. The Watch 5 suits those prioritising durability improvements, whilst outdoor adventurers should consider the Watch 5 Pro. All models share core health sensors, so your choice depends on budget and specific feature requirements.

Buy a refurbished Galaxy Watch 4 at the best price on Back Market

Back Market offers the Galaxy Watch 4 refurbished at competitive prices without sacrificing quality. Each watch is tested and verified by trusted refurbishers, complete with a minimum 12-month warranty. You'll benefit from excellent value on Samsung's health-focused smartwatch whilst supporting a more circular economy.

Our professional refurbishers conduct thorough quality checks, examining everything from the display and bezel (on Classic models) to sensor accuracy and charging performance. 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 Samsung technology has never been more straightforward.

What's the difference between Galaxy Watch 4 and Galaxy Watch 4 Classic?

The Galaxy Watch 4 and Watch 4 Classic share identical internal specifications, health sensors, and software features. The key difference is design: the Classic features a physical rotating bezel around the display for intuitive navigation through menus and apps, whilst the standard Watch 4 uses a digital touch bezel. The Classic has a more traditional watch aesthetic with a raised bezel and slightly bulkier profile, appealing to those who prefer classic watch styling. The standard Watch 4 offers a sleeker, more minimalist design that sits flatter on the wrist. Both come in 40mm and 44mm sizes (42mm and 46mm for the Classic). Choose the Classic if you value tactile navigation and traditional styling, or the standard Watch 4 for a more streamlined appearance.

How does body composition analysis work on Galaxy Watch 4?

The Galaxy Watch 4 uses bioelectrical impedance analysis (BIA) to measure body composition. Place two fingers from your other hand on the two buttons whilst wearing the watch on your wrist. A small, safe electrical current passes through your body, and the watch measures the resistance to calculate body fat percentage, skeletal muscle mass, body water, bone mass, BMI, and basal metabolic rate. For accurate readings, take measurements at consistent times, ideally in the morning before eating or drinking. Hydration levels, recent meals, and exercise affect results, so focus on long-term trends rather than daily variations. You'll need to input your height, age, and sex in Samsung Health for accurate calculations.

Does the Galaxy Watch 4 work with iPhone?

No, the Galaxy Watch 4 is designed exclusively for Android devices and does not support pairing with iPhones. You'll need an Android phone running Android 6.0 or later to set up and use the watch. Samsung watches work best with Samsung Galaxy phones, offering full feature access including body composition analysis, ECG, and blood pressure monitoring. Other Android brands can use most features, though some Samsung-specific functions may be limited. If you're an iPhone user looking for a smartwatch, the Apple Watch series provides equivalent ecosystem integration for iOS.

Can you monitor ECG with Galaxy Watch 4?

Yes, the Galaxy Watch 4 includes ECG (electrocardiogram) functionality through the Samsung Health Monitor app. To take an ECG reading, sit comfortably, place your watch arm on a flat surface, and rest a finger from your other hand on the watch button for 30 seconds. The watch analyses your heart rhythm and can detect signs of atrial fibrillation (AFib), a type of irregular heart rhythm. ECG availability varies by region due to regulatory requirements—it's available in many countries but not all. Results are intended for personal wellness tracking, not medical diagnosis. If the watch detects irregular rhythms or you have concerns about your heart health, consult a healthcare professional.

Are refurbished Galaxy Watch 4 devices covered by warranty?

Yes, all refurbished Galaxy Watch 4 devices on Back Market come with a minimum 12-month warranty. This warranty covers functional defects in essential components including the display, rotating bezel (on Classic models), buttons, body composition sensors, ECG sensor, heart rate monitor, GPS, charging system, 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 Galaxy Watch.
