Used Redmi Watch 4 Black by Xiaomi, used for about two months. There are no issues with its operation. A film (PDA Kobo Perfect Shield Plus) was applied immediately after purchase. I will send it with the film attached. In addition to the original band, I will include two replacement bands. One is gray (worth about 900 yen), and the other is navy blue, a type that can be attached and detached with one touch (worth about 1500 yen). Please purchase with the understanding that this is a used item.
