Selling an Apple Watch Series 4 GPS 40mm with a black wrist band. The watch is in great condition and works perfect. It comes with the box and all accessories, including an additional wrist band and charger. There are a few very minor scratches, as expected with a slightly used product. I bought the series 5, which is why I am selling this one.
