I bought the Apple Watch Series 6 in excellent condition, and it truly lives up to that description. The watch arrived in great shape, it feels brand new. Everything works perfectly, performance is smooth, and the battery life is exactly what I expected.

Another fantastic refurbished purchase from Backmarket! The watch was labeled as “fair,” but I can’t find any noticeable blemishes. More importantly, it operates flawlessly. This purchase confirms why I keep coming back to Backmarket. Thanks for a great product at an amazing price.

This was such a great deal and it looks brand new! Can’t even tell it’s refurbished. It came pretty quick too I ordered it 7/19 and received it 7/23. Originally the watch came with a black band but I switched it out with a different one.

Previous FitBit user, first time Apple Watch and I was surprised by all it can do. When it started vibrating with my Maps app, I was a little frightened until I figured it out! It works great but the charge only lasts a day, as I understan

I just want to say I am absolutely happy with my purchase! When i customized my order I chose “fair” and allowed my expectations to be set very low despite the price I was paying. When it was delivered it came a day early. When I opened the box the Apple Watch was BRAND NEW! Not one single mark, scratch or anything on this device. It also came with an Apple Watch band charger and you could tell it was new because it still had the plastic covering the front screen. I will always choose to purchase from back market! I will always trust “A4C” electronics for my refurbished items!

The watch does everything I need it to do. Wish I had payed a few extra bucks to get one in good shape. The watch looks and performs great minus the battery life. ( you get what you payed for ) overall I’m extremely happy with the purchase and the business I do with backmarket.com

I absolutely love my new watch. It performs perfectly, it came in excellent condition. It truly is an amazing watch. I was blown away with just how easy it is to use. This is my 5-6th purchase from Backmarket. They set the bar on refurbished electronics. They have a great selection, prices and tech support. I also enjoy reading their tips and suggestions. Thank you Backmarket!

Monitor even more of your health with the Apple Watch Series 6. The Series 6 adds pulse oximetry to measure your blood's oxygen levels (SpO2) in just 15 seconds, as well as showing you your VO2 Max (maximum oxygen consumption) score. These indicators can provide early warnings of possible respiratory conditions. They are joined by an optical heart rate monitor and the ability to record your own ECG (electrocardiogram). The Series 6 can even detect and help you with healthy habits, such as hand-washing detection, which displays a 20-second animated countdown as you scrub. Fitness is a large part of staying healthy, and the Apple Watch has a variety of ways to assist you in reaching your goals. Activity Rings displays three rings that correspond to movement, exercise, and standing. Stay mobile throughout the day to hit new personal bests as you close the rings. You can also choose from a variety of workouts, such as running, swimming, yoga, cycling, and more; with the watch recording and tracking their specific metrics. Whether inside or outdoors, the Series 6 can guide you via GPS and even provide continuous elevation updates on screen. Fitness and health metrics can be viewed, customized, and tracked on the Apple Watch's curved watch face that houses an always-on LTPO OLED Retina display. Even in direct sunlight, you can view the screen with just a glance. As you move, choose from a variety of music, podcasts, and audiobooks to entertain and motivate you. For added fun, share your activity rings with friends and challenge them to 7-day activity competitions. Throughout the day, the Apple Watch Series 6 keeps you connected with the world around you. When paired with your iPhone, you can make calls and send texts directly from your wrist, navigate your surroundings with Maps, buy items with Apple Pay, and use your voice to interact with Siri. Made to last in almost any kind of weather, the Apple Watch Series 6 is water-resistant up to 164'. Use its 32GB of built-in storage for apps, watch faces, music, and more.
