Apple Watch Series 3 Nike, Junk Item

This is something I received from an acquaintance.I used it for a while, but it stopped turning on and became unusable, so I'm listing it for sale.Would it be considered junk?I'm not very knowledgeable about it, so I don't know much about its functions or model.I will give the proceeds to my acquaintance.The blue band is an aftermarket addition, and the original black band is also included. superb for everyday use. first-class materials and excellent craftsmanship ensure long-lasting durability.
