Samsung Galaxy Watch 4 40mm WiFi (Renewed)

The Amazon Renewed program offers customers pre-owned or refurbished products that have been professionally inspected and tested to work and look like new. When a customer buys a new product and returns it or trades it in for a newer or different model, that product is then inspected and tested by Amazon-qualified suppliers to ensure it meets the standards of an Amazon Renewed item. If the product passes the inspection and testing process, it is then sold on Amazon as an Amazon Renewed product.

The Samsung Galaxy Watch4 is one such product that can be purchased through the Amazon Renewed program. This smartwatch features a 1.2-inch (30.2mm) Super AMOLED display with a resolution of 396 x 396 pixels and a pixel density of approximately 330 ppi. The watch is powered by a dual-core 1.15GHz processor and has a 247mAh battery. It runs on the Android Wear OS and features Samsung's One UI Watch 3 interface.

The Galaxy Watch4 is equipped with a range of sensors, including an accelerometer, barometer, gyro sensor, geomagnetic sensor, light sensor, optical heart rate sensor, electrical heart sensor, and a bioelectrical impedance analysis sensor. These sensors allow the watch to track various health and fitness metrics, including blood oxygen (SpO2) levels.

The watch's design is durable, featuring a glass front made of Gorilla Glass DX+ and a MIL-STD-810G compliant build. It is also water-resistant up to 50m (IP68) and compatible with standard 20mm straps. Additionally, the Galaxy Watch4 is ECG certified and has a blood pressure monitoring feature.

The Amazon Renewed Galaxy Watch4 is compatible with Android devices and supports Samsung Pay, making it a versatile smartwatch option. If you're not satisfied with your purchase, Amazon Renewed products are eligible for replacement or refund under the Amazon Renewed Guarantee.
